2015 Chicago Bears

The  Chicago Bears season was the franchise's 96th season in the National Football League, and the first season under head coach John Fox, the Bears' third head coach in four seasons.

The Bears entered the 2015 season with hopes of improving their 5–11 record in 2014. The team started the regular season on a poor note, losing their first three games. In the following six games, the team went 5–3, including a Thanksgiving win over the rivals Green Bay Packers. However, the Bears then lost the first three games in December, and were officially eliminated from playoff contention in week fourteen by the Minnesota Vikings. The following week against the Tampa Bay Buccaneers, the Bears improved upon their 2014 record with a 26–21 win. After losing in the final game of the season to the Detroit Lions, the Bears ended the season 6–10 and last in the NFC North.

Front office
After three years, general manager Phil Emery was fired on December 29, 2014. Later in the day, former Baltimore Colts, Cleveland Browns, and New York Giants general manager and presidential assistant of Bears' founder George Halas, Ernie Accorsi, was hired by the organization as a consultant to help the team find a new GM and head coach.

On December 29, NFL Network insider Ian Rapoport reported that the Bears had four candidates for the GM position: Kansas City Chiefs director of player personnel and former Bears' director of pro scouting Chris Ballard, Giants' vice president of player evaluation and 2012 finalist for the Bears' GM job Marc Ross, Tennessee Titans vice president of player personnel Lake Dawson, and Baltimore Ravens director of pro personnel Vince Newsome. Ravens' assistant general manager Eric DeCosta was also rumored to be a potential candidate by Dan Pompei, while Minnesota Vikings assistant GM George Paton declined an offer. DeCosta later announced his intention to remain with the Ravens. Later in the week, Chicago requested an interview with New Orleans Saints director of player personnel Ryan Pace and Houston Texans director of pro scouting Brian Gaine.

On January 6, the Bears conducted interviews for general manager with Gaine and Dawson. Ballard and Pace were interviewed the next day, and Pace was hired on January 8.

On January 13, director of pro personnel Kevin Turks was fired. The Bears hired former Saints area scout Josh Lucas as their director of player personnel on January 18.

In the scouting department, three scouts were hired on May 15. Ravens national scout Joe Douglas became the director of college scouting, Broncos assistant director of pro personnel Anthony Kelly as director of pro scouting and New York Jets area scout Christopher Prescott was hired in the same role.

Coaching
On the same day of Emery's firing, two-year head coach Marc Trestman was also fired, as was offensive coordinator Aaron Kromer. Quarterbacks coach Matt Cavanaugh's contract expired on the same day, and was not retained by the team.

In the hunt for a new head coach, the Bears requested interviews with Denver Broncos offensive coordinator Adam Gase, Arizona Cardinals defensive coordinator Todd Bowles, Seattle Seahawks defensive coordinator Dan Quinn, and Detroit Lions defensive coordinator Teryl Austin. The team also showed interest in Ravens' offensive coordinator Gary Kubiak and former Buffalo Bills head coach Doug Marrone. However, Kubiak announced on January 11 that he will stay with Baltimore.

The Bears went to Seattle on January 2 to interview Quinn, and the following day, interviewed Gase in Denver. Bowles was interviewed on January 8, while Austin and Marrone were interviewed five days later. On January 14, former Broncos' head coach John Fox, who had been released on January 12, was interviewed. Two days after his interview, Fox was hired, signing a four-year contract.

Looking for an offensive coordinator, the Bears requested an interview with Titans tight ends coach Mike Mularkey, but were denied. The Bears also showed interest in San Francisco 49ers quarterback coach Geep Chryst and former Kansas head coach Charlie Weis for the OC position. Gase was selected for the OC role on January 21. Defensively, 49ers DC Vic Fangio was hired on January 20, and brought 49ers defensive backs coach Ed Donatell to serve the same position, replacing Jon Hoke. At the NFL Scouting Combine, the Bears announced that they would be switching to a base 3–4 defense in 2015, a defensive scheme that Fangio had operated in San Francisco. Four of Fox's assistants with the Broncos were brought to Chicago: Broncos special teams coordinator Jeff Rodgers was hired on January 19, replacing Joe DeCamillis; the next day, assistant defensive backs coach Sam Garnes, offensive line coach Dave Magazu and assistant special teams coach Derius Swinton II were hired for the same positions they had served in Denver. The same day, defensive coordinator Mel Tucker, DeCamillis, tight ends coach Andy Bischoff, linebackers coach Reggie Herring and assistant special teams coach Dwayne Stukes were all officially released. To replace Cavanaugh and Herring, respectively, the Browns' Dowell Loggains and Atlanta Falcons' Glenn Pires were hired. Saints' assistant offensive line coach Frank Smith succeeded Bischoff at the tight ends coach spot after being hired on January 22. Three days later, defensive line coach Paul Pasqualoni left the Bears to join the Houston Texans, and Broncos DL coach Jay Rodgers was hired. Two days later, Bears assistant DL coach Clint Hurtt was reassigned to outside linebackers. On February 10, Ohio State running backs coach Stan Drayton joined the Bears to serve the same position. The next day, North Shore Senior High School assistant football coach and former NFL player Ben Wilkerson was hired as assistant OL coach, while incumbent OL coach Pat Meyer was not retained.

On January 21, strength and conditioning coach Mike Clark was fired. The next day, the Broncos' Jason George was hired to take his place. Broncos offensive quality control coach Bo Hardegree was hired as an offensive assistant on January 24. Three days later, Chicago offensive quality control coaches Carson Walch and Brendan Nugent were fired. On February 4, Central Michigan director of strength and conditioning Rick Perry was hired as an assistant strength coach. On February 10, the team announced they would not retain defensive quality control coach Chris Harris.

Roster changes
The Bears entered the new league year with 23 free agents, three of whom were exclusive rights free agents. The NFL's deadline to apply the franchise tag to players was on March 2, though the Bears did not tag any players. Free agency officially began on March 10.

Acquisitions
The first signing of 2015 was on January 28, when the Bears signed Toronto Argonauts receiver John Chiles to a reserve/future contract.

On the second day of free agency, the Bears signed Ravens linebacker Pernell McPhee to a five-year deal worth $38.75 million with $15.5 million guaranteed, and New York Giants safety Antrel Rolle ($11.25 million, $5 million guaranteed), and San Diego Chargers receiver Eddie Royal ($15 million, $10 million guaranteed) to three-year deals.

Afterwards, the Bears began signing players to one-year deals. On March 16, Vikings offensive lineman Vladimir Ducasse agreed to a contract; two days later, Chiefs long-snapper Thomas Gafford was signed. From March 24–27, the Bears added four defenders: defensive ends Jarvis Jenkins (Redskins) and Ray McDonald (49ers) on March 24, Tampa Bay Buccaneers linebacker Mason Foster on March 25, and Jacksonville Jaguars cornerback Alan Ball on March 27. On March 31, Falcons running back Jacquizz Rodgers joined the team. The first signing of April occurred on the first day, when Cardinals linebacker Sam Acho was acquired, and the next day, former Broncos center Will Montgomery was signed. Later in the month, on April 23, Falcons tight end Bear Pascoe was signed. June's first acquisition was also a one-year signing, when the team signed Tracy Porter on June 8.

On April 30, Chiefs safety Malcolm Bronson was signed to a two-year deal. On May 11, the Bears signed quarterback Pat Devlin, linebacker Kyle Woestmann and defensive tackle Terry Williams to three-year contracts. The next day, New York Jets tight end Chris Pantale was claimed off waivers. On June 18, safety Sherrod Martin and running back Daniel Thomas agreed to contracts of one year. Two days before the start of training camp, on July 27, the team signed Arizona Rattlers receiver/returner A. J. Cruz, while former Cardinals defensive lineman David Carter was acquired the next day.

Departures
On March 6, the Bears agreed to trade receiver Brandon Marshall to the Jets for a fifth-round draft pick; the trade did not become official until the start of free agency.

Defensive tackle Stephen Paea was the first of the Bears' free agents to leave the team, signing with the Redskins on March 10. Two days later, safety Chris Conte joined the Buccaneers. On April 9, cornerback Charles Tillman was signed by the Panthers. On May 13, 14 and 17, linebacker Darryl Sharpton, cornerback Danny McCray and receiver Josh Morgan departed the Bears to sign with the Cardinals, Cowboys and Saints, respectively.

On April 2, safety Anthony Walters and center Roberto Garza, who had been the team's longest-tenured player, were released after ten seasons. On May 11, linebacker Khaseem Greene and defensive lineman Austen Lane were released, and eleven days later, newly acquired defensive tackle Ray McDonald was released after being accused of domestic violence and child endangerment. On June 18, Pat Devlin and tight end Jacob Maxwell were released, as was Jonathan Brown ten days later.

Pre-draft
On March 26, NFL.com analyst Lance Zierlein wrote that the Bears' five biggest needs entering the draft were at outside linebacker, nose tackle, offensive line, safety, and wide receiver. The general consensus regarding the Bears' seventh-overall pick was to select an edge rusher like Vic Beasley (Clemson), Dante Fowler (Florida), Shane Ray (Missouri) and Randy Gregory (Nebraska), though WBBM-TV's Greg Gabriel believed the Bears should trade down from the pick, with players like Arik Armstead (Oregon), Danny Shelton (Washington), Eddie Goldman (Florida State), Jordan Phillips (Oklahoma) and Malcom Brown (Texas) being fits for the Bears' new 3-4 defense if the Bears were to trade down to a spot between 10th and 20th. Another suggested position to draft with the first-rounder was wide receiver, particularly Alabama's Amari Cooper, who, despite not being considered "a true need, a talent like his would be tough to pass up here." A defensive position considered for the pick was nose tackle; Sports Illustrated writer Andy Staples believed a 3-4 defense should focus on NT, and as a result, the Bears should draft Shelton, followed by a linebacker in later rounds, such as Eric Kendricks (UCLA), Benardrick McKinney (Mississippi State), Stephone Anthony (Clemson) and Paul Dawson (TCU) in the second round, and afterwards, draft a running back like Buck Allen (USC) or Mike Davis (South Carolina).

On April 6, Pittsburgh right tackle T. J. Clemmings visited the Bears. The Bears also hosted a visit for McKinney, Beasley, Gregory, Cooper, Fowler, Ray, David Irving (San Jose State), DeVante Parker (Louisville), Eli Harold (Virginia), Kevin White (West Virginia), Marcus Mariota (Oregon), Trae Waynes and Tony Lippett (Michigan State), Mario Edwards Jr. and Jameis Winston (Florida State), Breshad Perriman (UCF), Tyler Kroft (Rutgers), Byron Jones (Connecticut), Malcolm Agnew (Southern Illinois), Todd Gurley (Georgia), Bryce Petty (Baylor), Cornelius Edison (Portland State), Josh Shaw (USC), and D.J. Humphries (Florida). Of the 24 players, Irving was the only player to have a workout hosted. The team held a local Pro Day on April 7, which featured players from the Chicago area, including: Northwestern quarterback Trevor Siemian, safety Ibraheim Campbell and receiver Kyle Prater, quarterbacks Taylor Graham (Hawaii), Chandler Whitmer (Connecticut) and Matt Behrendt (Wisconsin-Whitewater), safety Corey Cooper (Nebraska), offensive lineman Arthur Ray Jr. (Michigan State) and tight ends Matt LaCosse (Illinois), James O’Shaughnessy (Illinois State) and E.J. Bibbs (Iowa State).

Draft class
The Bears attempted to trade quarterback Jay Cutler to the Titans for their #2 overall pick, but Tennessee was not interested. Eventually, the Bears drafted West Virginia receiver Kevin White with the seventh-overall pick; considered the top receiver in the 2015 draft class by NFL.com analyst Mike Mayock, White caught 109 passes for 1,447 yards and 10 touchdowns in 2014. In the second round, Florida State defensive lineman Eddie Goldman was selected; considered a first-round prospect who had fallen due to his toughness, the 2014 Associated Press All-American recorded 35 tackles, four sacks and eight tackles for loss in his final college season. With their third-rounder, Oregon center Hroniss Grasu was drafted; the 2013 and 2014 Rimington Trophy finalist, the Bears were convinced by guard Kyle Long to draft his former Oregon teammate. With White and Grasu's selections, this marked the first time since 2008 that the Bears drafted at least two offensive players with their first three picks. In the fourth round, Michigan State running back Jeremy Langford was selected; during his time with Michigan State, he recorded 2,967 rushing yards and 40 touchdowns on 577 carries, while also recording 18 games with 100+ rushing yards, the third-most in school history. He holds the Spartans' record for the most consecutive Big Ten Conference games with 100 rushing yards with 15, ending his college career with 16. The Bears drafted their second defensive player in the fifth round, Penn State safety Adrian Amos; having started 38 consecutive games for the Nittany Lions, Amos recorded 42 tackles and three interceptions in 2014, with career totals of 149 tackles, seven interceptions, three sacks and nine tackles for loss. The Bears' final pick of the draft was in the sixth round, drafting TCU tackle Tayo Fabuluje; the 2012 Big 12 Conference Newcomer of the Year, he skipped football in 2013 due to family issues before returning in 2014 to help TCU win the Big 12 title.

Each of the draft class members agreed to four-year deals with the Bears. Langford, Amos and Fabuluje were the first to sign, doing so on May 5. The following day, White and Goldman were signed. Grasu was the last player to sign a contract, agreeing to a deal on May 8.


 * Notes
 * The Bears traded their original 2015 fifth-round selection (No. 143 overall) along with their 2014 fifth-round selection to the Denver Broncos in exchange for the Broncos' 2014 fourth- and seventh-round selections.
 * The Bears traded wide receiver Brandon Marshall and their seventh-round selection (No. 224 overall) to the New York Jets in exchange for the Jets' fifth-round selection (No. 142 overall).

Undrafted free agents
After the draft, on May 3, the Bears signed 15 undrafted free agents. On offense, six players were signed: ECU quarterback Shane Carden, who completed 63.5 percent of his passes for 4,736 yards, 30 touchdowns and 10 interceptions in 2014; Coastal Carolina guard Chad Hamilton, who was named to first-team All-Big South Conference in 2013 and 2014; Arkansas tackle Cameron Jefferson, who was an honorable mention for the All-Mountain West Conference team while playing for UNLV; Illinois State receiver Cameron Meredith, who led the Redbirds with 66 receptions for 1,061 yards and nine touchdowns in 2014; Baylor receiver and punt returner Levi Norwood, who holds the school record for the most punt return touchdowns with two in 2013, while also catching 128 passes for 1,626 yards and 11 touchdowns; and Alabama tight end Brian Vogler, who recorded 17 catches for 125 yards and two touchdowns in four years. Defensively, seven players were signed: TCU linebacker Jonathan Anderson, who recorded 30 tackles and 4.5 tackles-for-loss in 2014; Rice cornerback Bryce Callahan, who recorded 145 tackles, 13 interceptions (second-most in school history), 14 tackles-for-loss, two sacks, two forced fumbles and a fumble recovery in 47 college games, including a career-best 43 tackles in 2014; East Central cornerback Qumain Black, a 2013 first-team All-Great American Conference member during his time at Northeastern Oklahoma A&M College, who had 25 tackles and an interception with East Central in 2014; UCF cornerback Jacoby Glenn, who recorded 48 tackles and seven picks in 2014, and was named second-team All-American (UCF's first All-American since 2007) and American Athletic Conference Co-Defensive Player of the Year; UCLA safety Anthony Jefferson, who led the Bruins with eight pass breakups while ranking third with 72 tackles, awarding him a spot on the second-team All-Pac-12 Conference roster; Miami defensive end Olsen Pierre, who recorded 96 tackles, nine tackles-for-loss, 2.5 sacks, two forced fumbles, a fumble recovery and six pass breakups in 44 college games; and Washington linebacker John Timu, who recorded 108 tackles, two interceptions, and two touchdowns in 2014. Chicago also signed two special-teamers: Toledo kicker Jeremiah Detmer, the 2013 Mid-American Conference Special Teams Player of the Year, who had an 84.4 conversion percentage during his career; and Old Dominion long snapper Rick Lovato, who didn't miss a game in college. However, Detmer was released on June 18.

Offseason activities
The Bears held a voluntary offseason program on April 13, with the players focusing on strength and conditioning. Due to having a new head coach, a voluntary veteran minicamp was held on April 28–30. A rookie minicamp was held on May 8–10, while ten organized team activities were scheduled, three of which were open to the media (May 27, June 3, June 10). Finally, a mandatory full-squad minicamp was held on June 16–18.

Players reported to Training Camp in Olivet Nazarene University in Bourbonnais on July 29, though practice officially began the following day. The camp lasted until August 16, though no practices were held on August 4, 9 and 12–14.

During the timespan of Training Camp prior to the first game of the preseason, various transactions occurred. On the first day of camp, rookie Chad Hamilton retired, and on July 31, Tyler Moore was signed to a three-year contract to take his place. On August 5, tight end Brian Vogler was released. Six days later, guard Ryan Groy was traded to the New England Patriots for linebacker Matthew Wells.

Schedule
The Bears preseason schedule was released on April 9. The team opened the preseason at home against the Miami Dolphins, who had defeated the Bears in their meeting in 2014, followed by visiting two 2014 playoff teams in the Indianapolis Colts and Cincinnati Bengals; the Bears had last faced the two teams in the season openers of 2012 and 2013, respectively. Chicago ended the preseason hosting annual preseason opponent Cleveland Browns, who the Bears had lost to in the 2014 preseason game.

Game summaries
The Bears struggled early in the preseason-opening game, starting with the Dolphins scoring on the opening drive with Ryan Tannehill's two-yard touchdown pass to Jarvis Landry, concluding a 14-play, 85-yard drive. On the first offensive play, tackle Jordan Mills was penalized for a false start, and after four plays, the Bears punted; Chicago would not score until early in the second quarter with Robbie Gould's 48-yard field goal. The Dolphins responded to the field goal with Caleb Sturgis' 31-yard field goal later in the quarter. With 1:02 left in the first half, backup quarterback Jimmy Clausen attempted to lead a two-minute drill, and the offense reached the Dolphins' 16-yard line, but with no timeouts and Josh Bellamy being unable to get out of bounds, the clock ran out. Early in the second half, cornerback Sherrick McManis pulled the ball away from Mike Gillislee, and recovered at the Dolphins' 37, which led to Gould's 23-yard field goal; after Miami punted, Gould narrowed the margin by one point with a 21-yard kick. On the Dolphins' next play, McLeod Bethel-Thompson was intercepted by John Timu; seven plays later, Ka'Deem Carey scored on a one-yard touchdown run to give the Bears the lead, followed by Clausen's two-point conversion pass to A. J. Cruz. In the fourth quarter, Bethel-Thompson was intercepted by Sam Acho on the Miami 13, which led to Gould kicking a 27-yard field goal; later in the quarter, the Bears increased their lead with Senorise Perry's 54-yard touchdown run, making the score 27–10. After the Dolphins turned the ball over on downs and the Bears punted, the game concluded with Miami's Josh Freeman being intercepted by Malcolm Bronson.

Against the Colts, the Bears led early with Gould's 50-yard and 38-yard field goals, and both teams traded the lead with each of their next scores in the half: Indianapolis scored on Andrew Luck's 5-yard touchdown run and eventual two-point conversion pass to Andre Johnson, which Chicago responded with Gould's 25-yarder, though the Colts ended the half with the 11–9 lead via Adam Vinatieri's 25-yard kick. During the first half, the Bears had a first quarter 12-yard touchdown scramble by Cutler nullified by lineman Kyle Long's holding penalty. The game's lone two interceptions occurred during the second quarter on consecutive drives: Indianapolis quarterback Matt Hasselbeck's pass for Donte Moncrief was intercepted by Terrance Mitchell, and Clausen's pass for Dante Rosario was underthrown, being intercepted by Sheldon Prince. The Bears reclaimed the lead on their first possession of the second half with Clausen's 12-yard touchdown pass to Bellamy, which was established after Jeremy Langford's 46-yard run. On the Colts' next driver, Hasselbeck was sacked by Acho, leading to Eddie Goldman recovering the ensuing fumble. The margin was increased on the fifth play of the Bears' next drive, with Langford scoring on a two-yard run.

Chicago's top four receivers, Alshon Jeffery, Eddie Royal, Marquess Wilson and Kevin White, were not active for the game in Cincinnati. During the game, Perry, Clausen, Tracy Porter, John Chiles and Jon Bostic also suffered injuries. Penalties were a concern for the Bears, who committed 12 for 117 yards; the offense also struggled on converting third downs, with only two of eleven successful. On defense, the Bears allowed the Bengals to score three unanswered touchdowns: in the first quarter with Andy Dalton's one-yard run, and in the second with A. J. McCarron's touchdown pass to Marvin Jones and Jeremy Hill's one-yard run. It would not be until the final six seconds of the half that the Bears scored, with Gould's 34-yard field goal. The first-team offense left the game during the third quarter, with all but one drive having ended in a punt, and on four of those drives, the unit failed to record a first down. Halfway through the final quarter, the Bears were able to make the score 21–10 after Ify Umodu blocked Kevin Huber's punt and returned it for an eight-yard touchdown.

Chicago scored first in the second quarter of the preseason-ending game against Cleveland with David Fales' 19-yard touchdown pass to Marc Mariani, after capitalizing on Lamarr Houston forcing Darius Jennings to fumble and Mitchell recovered. On the Browns' next drive, the Bears' Jonathan Anderson sacked Thad Lewis, leading to another fumble, this time recovered by Cornelius Washington; however, Gould missed a 43-yard field goal. In the third quarter, Fales was able to throw an 11-yard touchdown pass to Umodu after escaping Tank Carder's blitz. Later in the quarter, Sherrod Martin intercepted Lewis and scored on the ensuing 25-yard return. With 5:35 remaining in the game, Gould scored the final points of the game with a 28-yard field goal, as the Bears recorded the team's first preseason shutout since 1994. By the end of the game, the defense excelled, with seven sacks, three turnovers forced and limiting the Browns to 2.7 yards per play. The Bears concluded the preseason with a 3–1 record, while also not allowing a score in the second half across the four games; turnover-wise, the Bears forced ten, while allowing only one.

Schedule
The regular season schedule was released on April 21. Aside from the standard six games against NFC North teams, the Bears also played the AFC West and NFC West teams, along with the two last-place finishing NFC East (Washington) and NFC South (Tampa Bay) teams. The Bears' opponents had a combined record of 136–120 (.530), making their schedule the 13th-strongest in the league.

Week 1: vs. Green Bay Packers
The Bears opened the season hosting rival Green Bay Packers, the 191st meeting in the two teams' history and the third season opener in which both teams played each other in Chicago; the Bears held a 93–91–6 all-time lead, and also led the series in season opener record with 17–12–2. However, the Packers had won nine of the last ten games between the two, including the last game, a 55–14 victory at Lambeau Field. WBBM-TV analyst Jeff Joniak believed the Bears would have to run to gain an advantage against the Packers; when Chicago played Green Bay in week four last season, the latter had the 30th-ranked run defense, and allowed 235 rushing yards in that game. Additionally, the offense had to avoid drives that required long yardage, as the Bears had scored 74 points outside of the red zone (the 29th-best in the league), while also protecting Jay Cutler from Julius Peppers and Clay Matthews III. On defense, the new 3–4 defense faced a fast-paced Green Bay offense featuring Aaron Rodgers and Eddie Lacy. The Rodgers-led Packers, who led the NFC North in touchdowns with 58, along with having the highest average yards per play (6.17) in the NFL in 2014, also provided a challenge for the Bears defensive backs; blitzing Rodgers was also a liability, as he had a league-best 130.4 rating with 15 touchdowns and one interception against the blitz. However, the Packers did not have receiver Jordy Nelson, who had caught 13 touchdowns in 2014, as he had suffered an ACL tear during the preseason. David Fales, Tracy Porter, Ka'Deem Carey, Jon Bostic, Hroniss Grasu, Tayo Fabuluje and Cameron Meredith were inactive for the game.

The Packers won the coin toss, and elected to defer, meaning the Bears started the game with the ball. On the first possession of the game, the Bears offense reached as far as the Packers' eight-yard line, but ended with Robbie Gould kicking a 28-yard field goal. After the Packers punted, the Bears came close to allowing a turnover when Cutler was sacked by Peppers and fumbled, though the call was reversed. The next four drives of the game ended in scores for both teams: the Packers scored with Rodgers' 13-yard touchdown pass to James Jones, followed by the Bears reclaiming the lead in the second quarter with Matt Forte's one-yard touchdown run; the next two possessions concluded with field goals: Mason Crosby tied the game with a 37-yarder, though the Bears ended the first half with the 13–10 lead with Gould's 50-yarder. Prior to Forte's touchdown run, Gould had kicked a 27-yard field goal, but Sam Shields was offsides on the play, giving the Bears a 4th and 1, which the Bears capitalized with via Forte's one-yard run. The Bears then had two potential touchdowns nullified by Forte dropping a pass, and Alshon Jeffery's touchdown was canceled by Jermon Bushrod's holding penalty. The Packers also had a potential touchdown hurt by a penalty, as Rodgers had an eight-yard touchdown pass to Jones voided by holding penalties. In the second half, the Packers scored quickly with Jones' one-yard touchdown catch. The Bears responded with Gould's 44-yard field goal, but the Packers eventually scored again via Randall Cobb's five-yard touchdown catch. On Chicago's following drive, the offense drove to Green Bay's six-yard line to set up a first and goal situation. While Forte's four-yard run brought the Bears to the two, Cutler's passes to Eddie Royal, Jeffery and Royal again fell incomplete, leading to the Bears turning the ball over on downs. The Packers punted again, but the Bears failed to score when Cutler was intercepted by Matthews; the turnover set up Lacy's two-yard touchdown run to increase the score to 31–16 with 1:55 left in the game. With 34 seconds left, the Bears scored with Cutler's 24-yard touchdown pass to Martellus Bennett, narrowing the margin to eight points. However, Green Bay's Davante Adams recovered the onside kick, and the Packers ran out the clock to end the game.

Gould's first field goal of the game allowed him to set the franchise record for the most field goals with 244, breaking a tie with Kevin Butler. Forte recorded 184 rushing yards in the game, the most by a Bears running back in a loss since Walter Payton's 175 yards in a 1984 loss to the Packers.

Week 2: vs. Arizona Cardinals
Chicago hosted Arizona in week two, the 92nd meeting all-time; the Bears, who possessed a 58–27–6 record against the Cardinals entering the game, won the most recent meeting in 2012 28–13, though Arizona won the last game at Soldier Field in 2009 41–21. The Bears faced a 3–4 defense for the second consecutive week, and the Cardinals had a blitz-heavy defense. To attack it, Jeff Joniak wrote Matt Forte would have to be utilized. When passing, the Bears had to be wary of left-side cornerback Patrick Peterson; in 2014, Arizona's opponents only threw passes of at least ten yards to that side 29 times, the fifth-lowest in the NFL. As a result, teams attempted to throw ti the right, with 51 deep passes, though only 29.4 percent were completed, the sixth-lowest in the league. Defensively, the Bears had to provide pressure to Carson Palmer, who had excelled in the season opener against the Saints with a three-touchdown game, against a line that allowed no sacks in week one, while also focusing on challenging the speed of the Arizona receivers. Ego Ferguson, Ka'Deem Carey, Hroniss Grasu, Jon Bostic, Tayo Fabuluje were inactive for the game.

The Cardinals won the toss and decided to receive. On the opening kickoff, David Johnson returned it 108 yards for a touchdown. After both teams exchanged punts, Josh Bellamy caught a 48-yard touchdown pass from Cutler, his first career touchdown reception. On the Cardinals' ensuing drive, the Bears forced fourth down after Palmer's pass to Johnson went out of bounds, but was reversed after it was determined he had a knee and elbow inbounds. Two plays later, Arizona gained 42 yards on Palmer's pass to John Brown, added with a defensive pass interference penalty on Kyle Fuller, placing the offense at the Bears' 11-yard line. After two plays, Palmer threw a six-yard touchdown pass to Jaron Brown. On Chicago's next drive, Jeremy Langford scored on a one-yard dive. However, the Cardinals scored two touchdowns in 52 seconds: after Larry Fitzgerald's eight-yard touchdown reception, Tony Jefferson intercepted Cutler, scoring on the 26-yard return. Cutler tried to dive to tackle Jefferson, but landed on his right shoulder and suffered a hamstring injury; Jimmy Clausen replaced Cutler for the rest of the game. Despite losing Cutler, the Bears were able to score three points with Robbie Gould's 40-yard field goal, and got the ball back on the next drive with Jared Allen intercepting Palmer's pass intended for J. J. Nelson on the first play; however, the Bears had to settle for Gould's 23-yard field goal. In the third quarter, Clausen's pass for Marquess Wilson was intercepted by Patrick Peterson, with the Cardinals capitalizing on the turnover with Palmer's 28-yard touchdown pass to Fitzgerald. After the Bears punted, Arizona increased the score with Johnson's 13-yard touchdown run. Gould eventually kicked a 51-yard field goal to make the score 42–23, but Fitzgerald caught another touchdown pass, this time of nine yards, to widen the margin by 25 points, though Chandler Catanzaro's extra point was wide left.

The Bears fell to 0–2 for the first time since 2003, while the 48 points allowed were the most at home in team history.

Week 3: at Seattle Seahawks
The Bears' first away game of the season occurred in Seattle, who led the all-time series 10–6, including the last three regular season games. However, the Bears had won the last game in Seattle in 2009 25–19. The Bears offense, not featuring Jay Cutler nor Alshon Jeffery, faced a defense led by Kam Chancellor, who returned to the Seahawks after a holdout. Without Chancellor for the first two games of the season, the defense had allowed quarterbacks to complete 72 percent of their passes with a passer rating of 116.4. Jeff Joniak believed that to counter the Legion of Boom, the Bears had to balance the rushing and passing attacks, while watching for a blitz that pressured Aaron Rodgers 19 times in week two. On defense, the Bears had to watch for Russell Wilson, though he had struggled with pressure in the first two games, being sacked a total of eight times. Additionally, the run defense had to be aware of a running game led by Marshawn Lynch; the corps had averaged 121.5 yards per game. On special teams, the Bears had to stop speedy rookie Tyler Lockett, who had scored on a punt return earlier in the season. Asides from Cutler and Jeffery, Jon Bostic, Brandon Dunn, Tayo Fabuluje, Hroniss Grasu and Willie Young were inactive.

The Seahawks won the coin toss and kicked off. Before the Bears' first offensive play, they were penalized for delay of game, and eventually punted. After both teams each traded punts once, Seattle's Richard Sherman utilized a trick punt return, similar to one the Bears had utilized with Devin Hester and Johnny Knox in the past, to record a 64-yard return to the Bears' 19-yard line. Seattle eventually scored first with Steven Hauschka's 31-yard field goal. Five drives (all of which ended in punts for both teams) later, the Seahawks ended the first half with Hauschka's 21-yarder. Prior to the Seahawks' last drive, controversy over the Bears' last punt arose: after Pat O'Donnell punted, the ball started to bounce out of bounds, but it hit Seahawks linebacker Brock Coyle in the leg, making it available to recover, with Sherrick McManis taking advantage. However, the officials ruled the punt as downed by McManis, which led to John Fox challenging the call, though it stood. The Bears special teams struggles continued in the second half, when Lockett returned the opening kickoff 105 yards for the touchdown. The Seahawks increased the score with another touchdown later in the third quarter via Jimmy Graham's 30-yard touchdown catch from Wilson, followed by 45- and 48-yard field goals by Hauschka in the fourth quarter to make the final score 26–0.

The Bears were shutout for the first time in 194 games (a 15–0 loss to the Tampa Bay Buccaneers in week 17, 2002), which was then the sixth-longest streak in the league. After three games, the Bears had allowed 105 total points, the most since the 2003 season, when they allowed 111. Additionally, the Bears punted on all ten drives in the game, the first time since the data was first compiled in 1980. Despite the hardships, the defense improved, allowing only one touchdown after allowing five against the Cardinals; additionally, having the game as one of two teams without a sack, the Bears recorded four against Seattle, two each by Jarvis Jenkins and Pernell McPhee.

Week 4: vs. Oakland Raiders
Returning to Soldier Field for week four, the Bears hosted the Oakland Raiders, who held a 7–6 all-time lead entering the game. This was the first game between the two at Soldier Field since 2003, where the Bears won 24–21, and the first since 2011, when the Raiders won 25–20 in Oakland. The Bears offense faced a defense led by Khalil Mack, while the secondary is guided by 39-year old Charles Woodson, who possessed 61 career interceptions, and had sealed the Raiders' win the previous week against the Browns. However, the Raiders had struggled against tight ends, allowing five catches of at least 25 yards, with a total of 20 catches for 298 yards and five touchdowns across the first three games. On defense, Chicago was against Derek Carr, who led the Raiders offense to 74 combined points in the last two games, along with Amari Cooper, who had 20 receptions entering the game, while also recording a 68-yard touchdown in week two. Jeff Joniak wrote that the Bears had to prevent the Raiders from gaining yardage after touching the ball; the Raiders were seventh in yards after the catch, while Latavius Murray – who had recorded 139 rushing yards in week three, was ranked fourth in the league in rushing yards and was leading the AFC in yards per carry with 4.8 – ranked fifth in yards after contact. Cooper had 177 yards after the catch, the second-most in the league among wide receivers, while 53.7 percent of Carr's passing yards occurred due to these plays. In comparison, the Bears allowed the fewest yards after contact. David Fales, Patrick O’Donnell, Alshon Jeffery, Ka’Deem Carey, Hroniss Grasu, Jermon Bushrod and Jeremiah Ratliff were inactive.

The Raiders won the coin toss and deferred in the second half. The Bears managed to record an 80-yard drive to score on the opening possession via Jay Cutler's seven-yard touchdown pass to Eddie Royal. During the drive, lineman Charles Leno landed on center Will Montgomery's leg, injuring the latter and prompting Matt Slauson to replace him. Robbie Gould's extra point was blocked, and his struggles continued with the following kickoff when his squib kick bounced out of bounds. After the game's four next drives culminated with punts, the Raiders scored on Carr's 26-yard touchdown pass to Cooper; despite initially being ruled out of bounds, the Raiders challenged the call and the ruling was overturned. On the Bears' next series, Slauson botched the snap to Cutler, and the Raiders' Dan Williams recovered. Oakland capitalized on the takeaway with Roy Helu scoring on a four-yard touchdown reception, though the Bears responded with Cutler taking advantage of an open Martellus Bennett to score on a five-yard touchdown. On Oakland's next drive, Carr's swing pass to Murray was deflected and landed towards Pernell McPhee, intercepting the pass; Gould eventually kicked a 19-yard field goal. In the second half, the Raiders punted on the first drive, though they reclaimed the ball after Stacy McGee recovered Matt Forte's fumble. Oakland eventually took the lead with Sebastian Janikowski's 29-yard field goal. Gould eventually gave the Bears the lead back with Gould's 54-yard kick, and reclaimed possession of the ball with Murray dropping a pitch and Sam Acho recovered. However, the Bears gave the ball back when Cutler's pass for Bennett fell short and was intercepted by Woodson, leading to Janikowski's 41-yard field goal.

With 2:05 left in the game, Cutler began leading a two-minute drill: after a six-yard run by Forte, followed by a sack by Mack and incomplete pass to Josh Bellamy to bring up fourth down, Cutler successfully converted with a seven-yard pass to Bennett, who beat Keenan Lambert. Cutler's next pass to Marquess Wilson fell incomplete, and Forte's seven-yard run led to another third-down situation, which led to Cutler's first-down conversion of seven yards to Wilson with 56 seconds left. On the next set of downs, Cutler's pass for Cameron Meredith was overthrown, though a 12-yard pass to Royal allowed the offense to enter Oakland territory, where the Bears elected to use a timeout with 40 seconds remaining. The offense entered field goal range with Cutler's nine-yard pass to Wilson, followed by a two-yard run by Forte. With seven seconds left, the Bears used another timeout, and allowed Gould to attempt the 49-yard field goal; Gould successfully converted the field goal with two seconds remaining on the clock to give the Bears the 22–20 lead. In an last-second attempt to score, the Raiders attempted lateral passes on the kickoff return, but were penalized for an illegal lateral in the early stages of the play, and the Bears eventually recovered to clinch the win.

Gould was later named the NFC Special Teams Player of the Week, his third ST POTW honor and tying him with kickers Jeff Jaeger and Paul Edinger for the most in team history. The field goal was Gould's eleventh career game-winner. Forte ran for 91 yards in the game to increase his career rushing yards total to 8,071, becoming the 14th player in NFL history to record 8,000 and 3,500 career rushing and receiving yards, respectively, while becoming the second-fastest player to achieve the milestone with 111 games.

Week 5: at Kansas City Chiefs
For the fifth game of the season, the Bears visited Kansas City, who trailed the Bears 5–6 in the all-time series; the game was the first in Kansas City since 2003, which the Chiefs won 31–3. Entering the game, the Bears were plagued by injuries, with 16 players listed on the injury report: Jermon Bushrod (concussion) was ruled out, Antrel Rolle (ankle) was doubtful, and 13 others were questionable. Jeff Joniak wrote that the offense had to be cautious of Bob Sutton's 3–4 defense, particularly the front five guided by linebacking duo Tamba Hali and Justin Houston. However, the pass rush only had nine sacks in 2015. To combat the defense, the Chiefs' cornerbacks had to be targeted, particularly Jamell Fleming and rookie Marcus Peters, who was targeted the most among cornerbacks in the NFL and four touchdowns, respectively. Additionally, the Chiefs had allowed 15 touchdowns, the most in the NFL, and in the red zone, was ranked the worst in the league. Also, the Chiefs pass defense allowed eleven passing touchdowns and 295.5 passing yards per game (ranked 28th in the league), while recording only two interceptions. The Bears defense, which had recorded six sacks in the last two games, faced an offensive line that allowed a league-high 19 sacks. Despite the struggles on the OL, Chiefs quarterback Alex Smith had receivers like Jeremy Maclin, who had recorded 148 receiving yards in the previous game, though Smith had a 49.5 completion percentage to receivers, one of the worst in the league. In the rushing attack, the Chiefs had running back Jamaal Charles, who was tied with Matt Forte for the most rushes of ten yards or more in the NFL with eleven; however, Charles had fumbled 26 times in his career, including twice in 2015. On special teams, facing former Bears ST coordinator Dave Toub, the Kansas City return unit was led by Knile Davis (kickoffs) and De'Anthony Thomas (punts); Davis ranked fourth in the NFL in KR yards, while Thomas was tied for seventh in PR yards. The Bears' coverage unit took on Pro Bowl punter Dustin Colquitt, who was ranked fourth in gross punt average and third in net average, while allowing only 51 yards on the return, along with kicker Cairo Santos led the league in field goals. Bushrod, Rolle, Alshon Jeffery, Eddie Royal, David Fales, Patrick Omameh and Will Sutton were inactive.

The Chiefs won the toss and deferred until the second half. After the Bears and Chiefs' first drives ended with punts, the Bears' next possession started at their own nine-yard line after an 18-yard punt return by Marc Mariani was nullified by Jeremy Langford's holding penalty. Three plays into the drive, Chiefs Jaye Howard and Allen Bailey sacked Jay Cutler in the endzone, leading to a fumble that was recovered by Ramik Wilson and gave the Chiefs the touchdown. After getting the ball back, the Bears were able to score three points late in the first quarter with Robbie Gould's 44-yard field goal. The Chiefs eventually punted again, and the Bears were again pinned inside their own five-yard line; the drive stalled, and Pat O'Donnell punted from the endzone. Despite playing a team with offensive line struggles, the Bears failed to employ a pass rush during the Chiefs' next drive, and once they did on third down, Smith threw a pass to Thomas, who scored on the 19-yard play. Kansas City increased the margin to 17–3 with nine seconds left in the second quarter, with Santos' 35-yard field goal; Cutler kneeled to end the first half. On the Chiefs' first drive of the second half, the offense reached the Bears' nine-yard line, but Santos' field goal was blocked by Pernell McPhee, allowing the Bears to take over at their own 17. The first play of the Bears' drive was a ten-yard run by Forte for a first down, marking the Bears' first since the opening quarter, and the series concluded with Gould's 30-yard field goal. The next four drives of the game ended with punts, while one of the series, held by the Bears, concluded with a turnover on downs.

With 7:51 left in the game and down 17–6, Cutler attempted to lead another comeback for the second consecutive game. The first drive lasted eleven plays and 88 yards, concluding with Cutler throwing a 22-yard touchdown pass to Marquess Wilson in the corner of the left endzone. The Bears attempted to go for two, but Cutler's pass for Mariani was ruled out; after a challenge, the ruling was upheld. The Chiefs eventually punted again, with the Bears starting their next drive on their own 33. Cutler led the offense on an eight-play, 67-yard drive, concluding with a seven-yard touchdown pass to Forte despite dropping the snap. However, the Bears failed the two-point conversion. The Chiefs started their final drive on their own 33 with eleven seconds left in the game. Smith reached the Bears' 48 with a pass to Maclin, and on the next play, threw a nine-yard pass to Maclin. However, Maclin juggled the pass while going out of bounds. As a result, with two seconds left, the Chiefs elected to try a NFL record 66-yard field goal. However, Santos' kick fell short, giving the Bears the 18–17 win.

This was Chicago's first victory at Arrowhead since 1993 where the Bears won 18–17. Two team records were set during the game. After converting his second field goal of the game, Gould became the leader of the most points in franchise history with 1,168 points, surpassing Kevin Butler. The win was Cutler's 46th with the Bears, tying Jim McMahon for the most in team history.

Week 6: at Detroit Lions
The second NFC North game of the season took place in Detroit, when the Bears played the winless Lions. Although the Bears led the all-time series 96–69–5, the Lions had won the last four meetings. The Bears' offensive players had success against Detroit in the past: in 12 career games against the Lions, Jay Cutler threw for 2,669 yards, 17 touchdowns, seven interceptions and an 89.9 passer rating, while Matt Forte (in 14 games) had 1,066 rushing yards, six rushing touchdowns and four touchdown receptions, his most against any opponent. A potential weakness that Forte and the Bears rushing attack could exploit was the Lions' run defense; with the departures of defensive linemen Ndamukong Suh and Nick Fairley, the run defense, which had allowed a league-low 69.3 rushing yards per game in 2014, regressed in 2015, allowing 126.6 yards per game (ranked 27th in the league). The Lions pass defense also suffered during the season: the Lions allowed quarterbacks to complete 78 percent of passes and a league-high combined 128.7 passer rating, while also allowing the second-most plays of 20 yards or more, with 25. To take advantage of this, the Bears saw the returns of Alshon Jeffery, Eddie Royal and Martellus Bennett from injuries. As for the Bears defense, they faced an offense that recorded 4.9 yards per play, ranked 29th in the NFL. Lions quarterback Matthew Stafford had also struggled, having an average of 6.2 yards per pass, the worst in his six-year career, and had been benched in the Lions' week five game against Arizona. Detroit running backs also struggled, averaging only 2.8 yards per carry. As a whole, the Lions offense led the league in turnovers with 15. On special teams, the Lions led the league in kickoff returns of at least 20 yards, with running back Ameer Abdullah leading the NFL in the same category with nine. Terrence Mitchell, Antrel Rolle, Antone Smith, Shea McClellin, Nick Becton, Jermon Bushrod and Bruce Gaston were inactive.

The Bears won the toss and deferred. The Lions' opening drive concluded with a touchdown when Lance Moore beat Sherrick McManis to score on a 20-yard touchdown. Chicago retaliated with ten unanswered points via Robbie Gould's 27-yard field goal and Jeremy Langford's one-yard touchdown run, the latter occurring in the second quarter. The Lions reclaimed the lead with Stafford's eight-yard touchdown pass to Tim Wright, though the Bears managed to score three points with Gould's 23-yard kick. Late in the first half, the Lions reached the Bears' two-yard line, where Stafford threw a pass to Golden Tate; as he crossed the goal line, he was stripped by Kyle Fuller, with the pass being intercepted by Jonathan Anderson and ruled a touchback. However, referee Walt Coleman ruled the play as a touchdown, stating that Tate "took three steps and broke the plane." On Chicago's first drive of the second half, the offense, aided by Cutler's 46-yard pass to Marquess Wilson, reached the Detroit five, but Cutler's pass for Jeffery in the endzone was intercepted by Rashean Mathis. The Bears nearly regained the ball on the Lions' ensuing possession when Sam Acho stripped Abdullah, but Abdullah managed to recover. Eventually, the Lions punted, and when the Bears also punted on the next possession, T. J. Jones muffed it, and Josh Bellamy recovered. Gould later kicked a 38-yard field goal. On the Lions' next series, the Bears defense struggled, allowing Stafford to complete passes of 42 and 16 yards to Tate and Theo Riddick, respectively, followed by a 22-yard touchdown pass to Tate, though it was nullified by Calvin Johnson's holding penalty. The Bears were forced to punt again, but Pat O'Donnell's punt hit Corey Fuller in the leg and Chris Prosinski recovered. In the fourth quarter, the Bears scored on Cutler's 11-yard touchdown pass to Jeffery, and regained possession quickly when Stafford's toss to Riddick deflected off of his hand and Anderson intercepted it. The Bears gained the lead with Forte's two-yard run, followed by Cutler's two-point conversion pass to Forte. However, the Lions took the lead with their next two scores: Matt Prater's 32-yard field goal and Stafford's six-yard touchdown pass to Johnson. With 21 seconds left in the fourth quarter, the Bears drove 69 yards to the Lions' 11, where Gould tied the game with a 29-yard kick. In overtime, the first four drives ended with punts, and on the fifth, Prater kicked a 27-yard field goal to claim the 37–34 win.

The game featured three controversial officiating calls. Regarding the second quarter Tate touchdown, Fox NFL commentator Ronde Barber and Fox rules analyst Mike Pereira believed Tate had not controlled the ball while falling to the turf. On the contrary, NFL Vice President of Officiating Dean Blandino stated that Tate "controlled the pass right at the goal line. This is not a receiver who is going to the ground. He is taking his third step, he had demonstrated possession, had become a runner." Late in the fourth quarter, Pernell McPhee was penalized for roughing the passer when it appeared that he had been pushed into Stafford. During the Lions' game-winning drive in overtime, Willie Young was held, but no penalty was called. Due to the NFL's policies on criticizing officials, Cutler did not comment, while John Fox stated, "We’re not allowed to talk about officials."

Week 7: Bye week
The Bears entered the bye week with a 2–4 record, third in the division. To comply with the NFL's collective bargaining agreement, which required at least four straight off-days off for players on byes, the Bears only held practices on Tuesday and Wednesday.

Entering the bye, the Bears had the seventh-best third down conversion percentage with 43.68, while having 118 first downs converted, one more than that of teams that the Bears had played.

On October 22, Jeremiah Ratliff, who had been suspended for the first three games of the 2015 season, was released. Outside the Bears' training facility, he and Ryan Pace had "an animated exchange", forcing security to escort Ratliff out and Lake Forest police to report to the area; no police intervention occurred. Ratliff had reported to Halas Hall in poor condition, and when he was requested to leave and a relative to pick him up, he was "belligerent and insubordinate". To replace Ratliff, the Bears signed Jaguar Ziggy Hood later in the day.

Week 8: vs. Minnesota Vikings
The Bears returned from the bye week by hosting the 4–2 Minnesota Vikings. In their rivalry, the Vikings led the all-time series 55–51–2, the Vikings winning the last game 13–9, though the Bears won the last game at Soldier Field 21–13. Jeff Joniak wrote that the offense had to protect Jay Cutler; the Vikings defense sacked Matthew Stafford seven times in week seven, with a total of 17 in 2015. In eleven career games against Minnesota, Cutler excelled, throwing 23 touchdowns and 13 interceptions, with an 8-3 record. A player that Joniak believed Cutler could attack is cornerback Xavier Rhodes, who allowed four passing touchdowns and a league-worst ten penalties. Additionally, the running backs could target a defense that allowed six yards per carry, one of the worst in the NFL. On defense, the Bears had to watch for Adrian Peterson, who averaged 88 rushing yards per game, including two consecutive games with at least 120 yards in each. Another player was quarterback Teddy Bridgewater, who completed 25 passes to eleven players in week seven, while watching for the speed of the Minnesota receiving corps. Despite such successes, as a whole, the Vikings offense was averaging 325.5 yards per game, the third-least in the league. In the red zone, the Vikings scored touchdowns on 42.11 percent of their drives, among the worst in the NFL. Terrance Mitchell, Shea McClellin, Hroniss Grasu, Jermon Bushrod, Bruce Gaston, Ka'Deem Carey and Cameron Meredith were inactive.

The Bears won the coin toss and deferred until the second half. The Bears special teams unit struggled, with returner Marc Mariani muffing the return on both of the Vikings' first two punts. Despite this, the Bears took the lead with Robbie Gould's 55-yard field goal. However, Minnesota scored on Marcus Sherels's 65-yard punt return touchdown, the third return touchdown allowed by the Bears in 2015. Despite this, Sherels muffed his return on the ensuing punt; Blair Walsh eventually kicked a 43-yard field goal in the second quarter to make the score 10–3. After the game's next three drives ended in punts (twice by the Bears), the first turnover of the game occurred when Kyle Fuller intercepted Bridgewater's pass for Stefon Diggs. The Bears capitalized on the takeaway with Cutler's 21-yard touchdown pass to Alshon Jeffery, who jumped over Rhodes to make the catch in the left corner of the endzone. In the third quarter, the Bears reclaimed the lead with Gould's 33-yard field goal, and after the Vikings punted, had the chance to increase the margin to six points on Gould's 51-yard attempt. However, Gould's kick went wide left, his first miss of the season and ending a 17-kick streak. Minnesota took advantage by tying the game via Walsh's 48-yard field goal. The game's next two possessions ended with touchdowns for both teams: the Bears scored with Cutler, whose targets (Jeffery and Mariani) were unavailable, running four yards and colliding with safety Harrison Smith at the goal line for the touchdown. Afterwards, the Vikings tied the score with Bridgewater throwing a pass to Diggs, who escaped Sherrick McManis to score on the 40-yard play. With 1:49 left in the game, the Bears' next drive ended with a punt to the Vikings' 22-yard line. However, aided by Bridgewater's 35-yard pass to Charles Johnson, Walsh kicked a 36-yard field goal as time expired to seal the win.

On Cutler's touchdown pass to Jeffery, he tied Sid Luckman for the most touchdown passes in Bears history with 137. Defensively, Pernell McPhee recorded his fifth sack during the game, and he became the first Bears player since Brian Urlacher in 2000 to have at least five sacks and one interception in the first seven games. During the second half, Matt Forte suffered a knee injury, and along with Eddie Royal, were missed the following week's game. The loss of Forte had been crucial for the Bears, as he had been responsible for 32 percent of yards gained in 2015, the most among running backs.

Week 9: at San Diego Chargers
On Monday Night Football, the Bears traveled west to face the 2–6 San Diego Chargers. The two teams last met in 2011 at Soldier Field, the Bears winning 31–20, though their last meeting in San Diego was in 2007, which the Chargers won 14–3, and the last MNF game in San Diego was a Chargers 20–7 victory in 1984; in eleven games, the Bears led the series 6–5. Jeff Joniak wrote that the Bears offense could capitalize on a defense that allowed the most yards after the catch in the NFL. Additionally, offenses often started drives at 32-yard line, ranked 31st in the league, while the Chargers also had the least points off turnovers with seven. The Chargers were also allowing 6.34 yards per play, the second-worst in the NFL. To attack, the offense would balance passes that focused on favorable receiver/cornerback matchups and run with Jeremy Langford, who was making his first career start with Matt Forte out. Defensively, the Bears faced an offense struggling with injuries, particularly at the line: of the five positions, four have seen two or more players starting. However, quarterback Philip Rivers excelled despite the injuries, having thrown for 18 touchdowns and 7.9 yards per pass, both of which were among the highest in the NFL; Rivers' performance had also enabled him to be in position to overtake Peyton Manning's single-season passing yards record. The Chargers had the top-ranked offense in the NFL, and also ranked first in yardage after the catch. Another offensive player that the Bears faced was tight end Antonio Gates, who led the league in career touchdowns with 101. However, the San Diego running game was struggling, with 3.6 rushing yards per play, which ranked 30th in the league. Special teams-wise, both teams were among the worst in the NFL: the Chargers were ranked 30th in average return yardage allowed, while the Bears were 31st; the former also allowed a league-high ten returns of 30-39 yards. For the Chargers' punt return unit, they had only one yard in 2015. San Diego also had league-worsts in starting yard line after kickoffs with 19.3 yards, drives starting within their own 20-yard line (11) and average starting area (21). Forte, Eddie Royal, Harold Jones-Quartey, Shea McClellin, Hroniss Grasu, Tayo Fabuluje and Ziggy Wood were inactive.

The Chargers won the coin toss and elected to kick off. Despite reaching the Chargers' 28-yard line, two scoring opportunities were denied with Jason Verrett deflecting Jay Cutler's pass for Alshon Jeffery and Robbie Gould's field goal sailing wide left. Afterwards, the Chargers scored with Danny Woodhead's 14-yard touchdown catch from Rivers. On the Bears' next possession, the offense entered Charger territory again, reaching as far as the 10-yard line, where Cutler was sack-stripped by Melvin Ingram, with the ball being recovered by Eric Weddle, though the Chargers failed to capitalize and punted. After the Bears punted as well, they reclaimed the ball when Tracy Porter stripped Dontrelle Inman and Christian Jones recovered. However, after two plays, Verrett intercepted Cutler's pass for Jeffery, returning it 68 yards for the touchdown; the Chargers eventually missed the extra point, making the score 13–0. On the next drive, Cutler threw a one-yard touchdown pass to Martellus Bennett. After both teams exchanged punts, the Chargers scored the final points of the first half with Josh Lambo's 31-yard field goal. In the second half, after the Chargers punted, Gould's 34-yard field goal attempt hit the left upright. San Diego punted again, and the Bears engineered a 93-yard drive that culminated with Langford scoring on a one-yard run. The Chargers increased the margin to five points with Lambo kicking a 22-yard field goal. Guiding an 80-yard drive, Cutler threw a 25-yard pass to Zach Miller, who caught the pass with one hand as he scored the go-ahead touchdown. Afterwards, Langford scored on the two-point conversion. The Chargers' final drive fell apart with plays like Lamarr Houston's two sacks, and on 4th down and 23, Rivers' deep pass fell incomplete. With 1:09 left in the game, Cutler kneeled three times to end the game.

With Cutler's touchdown to Bennett, he overtook Sid Luckman for the most passing touchdowns in franchise history with 138. Additionally, his final touchdown marked his twelfth fourth quarter touchdown, the most in the league. Miller's touchdown catch was his first since the 2011 season.

Week 10: at St. Louis Rams
Week 10's game was on the road in St. Louis, where the Bears played the 4–4 Rams. Historically, the two teams have played each other often, with the Rams joining the Cardinals as the most common opponent outside of the NFC North; the Bears held the series lead 52–36–3, though the Rams won the last game in 2013 42–21. Chicago's offense faced a defense with a stingy pass rush that featured 14 players with at least .5 sacks and eight with at least two. The rush had the second-most sacks in the league with 27, while Robert Quinn, despite missing the previous week's game with a knee injury, led the Rams with five. The Rams blitzed often, with six sacks on first down and five on second and third, with the combined 16 sacks on blitzes being the most in the league. The St. Louis secondary starred Janoris Jenkins and Trumaine Johnson, who broke up a combined 18 passes and allowed only two touchdowns in 2015. As a unit, the Rams defense allowed no touchdowns in the last ten quarters, while also having the second-best scoring defense in the NFL with 13.8 points per game, while also being one of three teams to force at least 70 negative plays. Jeff Joniak wrote that the Bears had to excel on third down; the Bears' 30th-ranked third down offense took on a defense that was ranked fifth in the category. For the Bears defense, rookie running back Todd Gurley was a target; in his first four games, he averaged 141 rushing yards on 22 attempts, and by week ten, had the fourth-most rushing yards in the league and a league-high 5.6 yards per carry. Additionally, the defense had to pressure quarterback Nick Foles: in the red zone, he completed only 47 percent of his passes with two interceptions; on third down situations, he completed only 46 percent with four interceptions; when blitzed, he completed 54 percent with five sacks, though he also has five touchdowns. Like the Bears, the Rams' third-down offense struggled, being ranked last in third down conversions with 23.8 percent. Special teams-wise, the punt unit had to stop Tavon Austin, who scored one of the NFL's eight punt return touchdowns in 2015. To get to Austin, punter Pat O'Donnell's hang time of 4.56 seconds (third-best in the NFL) could allow the unit's gunners to reach him. In contrast, the Rams kick return team was struggling, being ranked 30th with nine starts after kickoffs within their own 20-yard line, while also ranking 23rd in kick return yards with 22.4. Rams kicker/punter duo of Greg Zuerlein and Johnny Hekker are among the best in the NFL: Hekker had a gross punt average of 48 yards, one of seven punters to do so, while also being ranked fourth in net average with 43.3; Zuerlein had kicked a 61-yard field goal against the Vikings in week nine, but was missing a league-high seven field goals, including two that were blocked. Eddie Royal, Matt Forte, Deonte Thompson, Harold Jones-Quartey, Hroniss Grasu, Ziggy Hood and Pernell McPhee were inactive.

The Bears won the coin toss and elected to kick off. The Rams scored on the opening possession with Gurley's six-yard touchdown run, but the Bears tied the score on a two-play drive; after Jeremy Langford was stopped for a one-yard loss, Jay Cutler threw a short pass to Zach Miller, who managed to break free and score on the 87-yard play. The next drive for the Rams saw the offense go three-and-out, but on the punt return, Marc Mariani was quickly hit by Bradley Marquez and fumbled, with the ball being recovered by St. Louis' Maurice Alexander. On the first play since the turnover, Austin scored on a 17-yard reverse, but the touchdown was nullified by Greg Robinson's holding penalty; the Rams eventually had to settle for Zuerlein's 26-yard field goal. After the Bears punted, they regained possession on the first play of the Rams' next drive, when Shea McClellin stripped Tre Mason and recovered the ball. Robbie Gould eventually kicked a 35-yard field goal to tie the score at the end of the first quarter. The Rams punted on their next drive, and the Bears took the lead with Cutler throwing a two-yard touchdown pass to Miller. St. Louis later punted again, and Chicago's next series started at their own 14-yard line due to Alan Ball's holding penalty on the punt return. After Langford's three-yard run, Cutler held off a blitzing defense to throw a screen pass to Langford, who scored on the 83-yard play. The two teams exchanged punts for the remainder of the half; the first three drives of the second half also ended in punts. Afterwards, the two teams traded field goals, Zuerlein's being 38 yards and Gould's being 33 yards. On St. Louis' next drive, the team elected to try a fake punt, but Hekker's pass to Cody Davis fell short. The Bears increased the lead to 17 points with Gould's 36-yard field goal, and after the Rams' turned the ball over on downs again, scored on Langford's six-yard touchdown run. The next two drives ended with turnovers for both teams: Willie Young intercepted Foles, but Ka'Deem Carey fumbled after being hit by Rodney McLeod, with the fumble being recovered by Aaron Donald. With 2:23 left in the game, the Rams reached the Bears' 28-yard line before time expired.

Miller's first touchdown was the longest catch by a tight end since Byron Chamberlain's 88-yard play in 1999 and the longest touchdown reception by a Bear since Matt Forte's 89-yard score in 2010. With the score and Langford's 83-yard touchdown, the Bears became the first team since the 2006 Buffalo Bills to score multiple touchdowns of at least 80 yards in a game.

Week 11: vs. Denver Broncos
John Fox, joined by coordinators Adam Gase and Jeff Rodgers and quarterback Jay Cutler, faced their former team in the Denver Broncos for week eleven. In 14 games, the two teams split the series, though the Broncos won the most recent game in 2011 13–10. In the last game at Soldier Field, the Bears won 37–34. The offense took on one of the league's top defenses, Denver's pass rush leading the NFL in sacks with 32, with twelve players with at least .5 sacks. The Broncos defense was allowing the fewest average yards with 277.3, while also allowing the third-least points per game with 18.7. Despite DeMarcus Ware being out with a back injury, the Broncos still had Von Miller, who had more than five sacks in 2015. For the Bears, despite Alshon Jeffery and Eddie Royal's injuries, Martellus Bennett and Zach Miller could still play a role. If passing, Cutler had to watch for defensive lineman Malik Jackson, who had four pass breakups in the previous four games. When the Bears decide to run, they faced a run defense that led the league in multiple categories, including sack percentage. The Broncos offense was without Peyton Manning, and in his place was Brock Osweiler. Osweiler, who had 305 career passing yards, had only played in garbage time during his NFL career, but fits Gary Kubiak's West Coast offense. Jeff Joniak believed with Osweiler, the Broncos' plays, which consisted of 64 percent passes, would decrease, though tight ends Owen Daniels and Vernon Davis could be targeted more often. Meanwhile, Denver's rushing attack was struggling during the season, with an average of 86 rushing yards per game, 29th-ranked in the NFL.

The Broncos won the coin toss and deferred until the second half. After the Bears punted, Osweiler threw a pass to Demaryius Thomas, who escaped Chris Prosinski to score on the 48-yard play. After both teams exchanged punts, the Bears scored their first points of the game in the second quarter with Robbie Gould's 46-yard field goal, and narrowed the margin to one point when Gould scored on a 37-yard kick. Denver and Chicago traded punts again, but the former scored with Brandon McManus' 24-yard field goal as time expired in the second quarter to make the score 10–6. The first three drives of the second half ended with punts, though the first turnover of the game occurred on the next series, when Cutler's pass for Marquess Wilson was intercepted by Danny Trevathan. However, the Broncos failed to capitalize when Ronnie Hillman was tripped by Osweiler's feet on fourth down. Afterwards, aided by two consecutive 29-yard plays (via Brandon Marshall's defensive pass interference, followed by Wilson's 29-yard catch), the Bears reached the Broncos' 19-yard line, where Gould eventually kicked a 37-yard field goal. The Broncos later increased their lead by eight when Osweiler threw a ten-yard touchdown pass to Cody Latimer. On the Bears' next series, Cutler capitalized on a late hit by T. J. Ward and a 40-yard pass to Wilson to reach the Broncos' seven-yard line. Despite reaching as far as the four, the Bears turned the ball over on downs with three consecutive incomplete passes. Although Denver punted again and the Chicago offense reaching the Broncos' 33-yard line, Cutler was hit from behind by Marshall while throwing, and the ball was intercepted by Malik Jackson. The Broncos were forced to punt again, and with 1:25 left in the game, the Bears drove 65 yards, where Jeremy Langford scored on a two-yard run. However, Langford was stopped short on the two-point conversion, and on the onside kick, Thomas recovered. Osweiler kneeled once to end the game.

The Bears ended the game with no penalties for the first time since 1995 against the Philadelphia Eagles and becoming the 24th team to do so in the last 15 years; the Bears also became the first team to accomplish the feat in a loss since the 2013 Packers' loss to the Bears in week nine. The defense recorded five sacks, the team's most in 2015.

Week 12: at Green Bay Packers

 * Thanksgiving Day game

The second game of 2015 against the Packers was held on Thanksgiving in Green Bay. The two teams, in their 190th meeting, had never played each other on the holiday; on Thanksgiving Day games, the Bears were 16–15–2, while the Packers were 14–19–2. Chicago's offense took on a defense that ranked second in the league in first quarter points allowed with 1.9, along with a defense that recorded six sacks in week eleven against Minnesota. Jeff Joniak added that the offense had to improve its red zone performance; against Denver, the Bears failed to score on three of the four trips to the red zone, leading to a 41.2 percent touchdown efficiency in 2015; in ten games, the Bears were only able to score 14 touchdowns within the 20-yard line. On the other side, Joniak stated the defense had to stop the Packers offense early; since 2014, the Packers had outscored opponents 151–27 at Lambeau, while also leading the league in first quarter points with an average of 7.6. Aaron Rodgers had thrown eight first quarter touchdown passes (the most in the NFL) in 2015, while the Packers had a league-best +57 scoring differential. Meanwhile, the Bears defense had allowed nine touchdowns in the first, though the defense had not given up a touchdown in the third quarter. Joniak also wrote that the Bears had to "match and surpass the emotion" on a night that featured Brett Favre's jersey retirement "with their most physical, error-free and consistent performance". Eddie Royal, Ka'Deem Carey, Martellus Bennett, Antrel Rolle, Jacoby Glenn, Nick Becton and Will Sutton were inactive.

The Bears won the toss and deferred. The first four drives of the game ended without scores, as the Packers turned the ball over on downs during their first drive and the ensuing series were punts. On the next drive, Tracy Porter intercepted Rodgers, but was penalized for illegal contact, and the play was nullified. Afterwards, Rodgers threw a 25-yard touchdown pass to Lacy. The Bears' woes continued with the following kickoff, when Marc Mariani and Deonte Thompson collided while attempting to catch the kick and the latter had to kneel in the endzone for the touchback. The next four possessions led to punts; on Green Bay's next drive, Lacy recorded a 15-yard run, but was hit from behind by Chris Prosinski and fumbled, with the ball being recovered by Lamarr Houston. Chicago took advantage of the takeaway when Jay Cutler threw a three-yard touchdown pass to Zach Miller. However, on the next kickoff, Bryce Callahan missed a tackle and allowed Jeff Janis to record a 64-yard return; the Packers eventually converted it into a 22-yard field goal. Assisted by a 37-yard kickoff return by Thompson, the Bears offense scored with Cutler's 20-yard touchdown pass to Marquess Wilson, but the play was overturned after he was downed at the one. Afterwards, Jeremy Langford's one-yard run gave the Bears the 14–10 lead. Mason Crosby kicked a 50-yard field goal to end the half. The third quarter featured no scores, though the Bears' last drive of the quarter (which lasted into the final quarter) ended with Robbie Gould's 21-yard field goal to extend the lead by four points. After two further punts, Rodgers' slant pass for Davante Adams was intercepted by Porter. However, the Bears were unable to capitalize, and punted. With 2:23 left in the game, the Packers drove from their own 20-yard line to the Bears' eight. Rodgers' passes to James Jones, Richard Rodgers and Adams all fell incomplete, and Cutler kneeled once to seal the win.

With the win, the Bears won their third consecutive away game for the first time since 2012. Over the last four games, the Bears allowed less than 20 points in each, also last accomplished in 2012. The game averaged 27.8 million viewers, the most-watched Thanksgiving primetime game in NFL history and the second-highest viewed regular season game for NBC.

Week 13: vs. San Francisco 49ers
The 3–8 San Francisco 49ers visited Soldier Field in week thirteen; in 63 all-time meetings, the 49ers held the lead 32–30–1, though the Bears won the last game in 2014 28–20. The Bears offense took on a defense featuring linebackers NaVorro Bowman, Aaron Lynch and Ahmad Brooks, who had a combined 12.5 sacks in 2015, including 6.5 by Lynch. Alshon Jeffery provided a size advantage over cornerbacks Tramaine Brock and Kenneth Acker, the duo having a combined 90 tackles, six interceptions, and 14 pass breakups. As a unit, the 49ers defense had struggled, allowing an average of 400 yards, 8.13 yards per pass (29th overall), 17 touchdown passes and a 100.5 opponent quarterback rating (also 29th-ranked). Despite these troubles, the 49ers had held the Cardinals, who had the league's best scoring offense, to just 19 points in week twelve. As for the Bears defense, the 29th-ranked rushing defense took on a running attack without Carlos Hyde. 49ers quarterback Blaine Gabbert had been improving, throwing for 318 yards against Arizona, while his top receiver Anquan Boldin had recorded 44 catches for 558 yards, 28 of which resulted in first downs. However, the San Francisco offense had the fewest points in the NFL with 152, a league-low 14 combined touchdowns, and a worst-ranked 31 plays of at least 20 yards. Meanwhile, the Bears had allowed an average of 17 points per game in the last five, the fourth-fewest in the league. Marquess Wilson, Eddie Royal, Antrel Rolle, Nick Becton, Jacoby Glenn, Antone Smith and Bruce Gaston were inactive.

The Bears won the coin toss and elected to defer. The 49ers went three-and-out and punted; on the return, the Bears behaved as if Marc Mariani was returning on one side of the field, though Bryce Callahan actually returned it, and scored on the 65-yard play. However, a holding penalty on LaRoy Reynolds nullified the play. The Bears eventually scored a field goal with Robbie Gould's 40-yard kick. After the 49ers punted again, the Bears scored another field goal, this one being 51 yards. San Francisco subsequently punted, but scored on the second play of the Bears' next drive when Jimmie Ward intercepted Jay Cutler's screen pass for Alshon Jeffery and returned it 29 yards for the touchdown; the score remained tied after Eddie Goldman blocked the extra point. Chicago's next drive lasted into the second quarter, where Matt Forte took advantage of two consecutive 14-yard plays to score on a five-yard run. The 49ers scored on their drive with Shaun Draughn's one-yard touchdown run to tie the score. The first half ended with both teams tied 13–13. The Bears received the ball to start the third quarter, but failed to score when new long snapper Patrick Scales' snap was low and Gould missed the 40-yard kick. The next seven drives all ended in punts; the trend was broken when Ka'Deem Carey scored on a four-yard run, followed by San Francisco retaliating with Gabbert scoring on a 44-yard run. On the ensuing kickoff, Deonte Thompson's return went 74 yards to reach the 49ers' 28-yard line. On the drive, the Bears ran on each play, forcing the 49ers to use all three timeouts. With two seconds left, Gould's 36-yard field goal sailed wide left, resulting in overtime. The 49ers won the coin toss but punted, though the Bears were also forced to punt. On the first play of the next series, Gabbert threw a 71-yard touchdown pass to Torrey Smith to seal the win.

Week 14: vs. Washington Redskins
The fourteenth week of the season featured a game between 5–7 teams as the Washington Redskins visited Soldier Field. In 48 games, the Redskins led the series 24–23–1 and had won the last five meetings. The Chicago offense took on a Washington defense that excelled against passers, being ranked tenth in the category; Dashon Goldson led all defensive backs in tackles with 95, while Bashaud Breeland led the team in passes defended with 13. The Redskins defensive rush, which had 20 sacks in 2015, was led by Ryan Kerrigan, who has 6.5. Despite such performances, the Redskins rush defense was ranked 29th in yards per carry with 4.64 and 25th in average rushing yards at 124.2. Jeff Joniak writes that the Bears could exploit this with the three-man rushing attack of Matt Forte, Jeremy Langford, and Ka'Deem Carey. On defense, the Bears faced a Kirk Cousins-led offense that focuses on quick passes; Cousins completed a league-high 68.6 percent of his passes, with 7.1 yards per pass. One of Cousins' main targets was tight end Jordan Reed, who scored six touchdowns and led the Redskins in yards after the catch. Rankings-wise, the pass attack was ranked 17th in the league in passing yards per game and 16th for yards per play. Joniak states that the Bears had to force turnovers, and an area was on third down, as five of Cousins' interceptions had been on third down.

The Bears won the coin toss and elected to defer. Washington recorded a 15-play, 80-yard drive en route to scoring on Alfred Morris' one-yard touchdown run. After the Bears punted, the Redskins scored again with Cousins' fake read option leading to a three-yard touchdown run in the second quarter. Chicago's woes continued when the offense began the next drive on their own seven-yard line, and despite reaching the Washington 49, Jay Cutler was strip-sacked by Trent Murphy, who recovered the fumble. The Redskins failed to capitalize on the turnover and punted; the following two drives also ended with punts. With 52 seconds left in the first half, the Bears took over at their own 42, and managed to score with 18 seconds left when Cutler threw a 20-yard touchdown pass to Alshon Jeffery. Cousins kneeled once to end the half. After the Bears punted on the first drive of the second half, Cousins threw a five-yard touchdown pass to Reed. The Bears responded with Cutler's nine-yard touchdown pass to Zach Miller, who managed to escape DeAngelo Hall and made contact with Goldson as he reached the endzone. The score was the Bears' first third quarter touchdown of 2015. Afterwards, Cousins' pass for Pierre Garcon was intercepted by Kyle Fuller, and the Bears took advantage with Forte's seven-yard touchdown run to tie the score. Dustin Hopkins gave the Redskins the 24–21 lead on the first drive of the final quarter with a 47-yard field goal. Five drives later, the Bears attempted a 50-yard field goal with 1:40 left in the game. However, Robbie Gould's kick sailed wide left, and the Redskins ran the ball three times to end the game.

Week 15: at Minnesota Vikings
The second game of the Bears-Vikings rivalry took place in Minneapolis and was the third game at TCF Bank Stadium; the Bears won the first game in 2010 while the Vikings won in 2014. To succeed against the Vikings, Jeff Joniak writes that the Bears had to excel at the start of the game; offensively, the Bears had a first quarter scoring differential of -48, 31st in the league, while scoring only twice on game-opening possessions. In the third quarter, the Bears scored a league-worst 32 points; in comparison, the Vikings defense had allowed only one touchdown on opening drives and a league-low 37 points in the third quarter. The defense took on a Vikings offense spearheaded by Adrian Peterson, whose 1,251 yards led the league. On special teams, the Vikings led the league in post-kickoff starting position, while being ranked third in returns of at least 20 yards with 26 and first in returns of at least 40 yards with five. Additionally, kickoff returner Cordarrelle Patterson led the league in return average with 31.1 yards. Christian Jones, Cameron Meredith, Bryce Callahan, Nick Becton, Tayo Fabuluje, Jacoby Glenn and Antone Smith were inactive.

The Vikings won the toss and deferred. Despite a 49-yard kick return by Deonte Thompson, the Bears' struggles began quickly, with the drive stalling after a holding penalty on Hroniss Grasu and a sack. Afterwards, the Vikings scored on their first drive when Stefon Diggs beat Tracy Porter to score on a 15-yard touchdown. The Vikings increased the score with Blair Walsh's 53-yard field goal in the second quarter. After the next two drives ended with punts, Alshon Jeffery caught a ten-yard touchdown pass from Jay Cutler to draw the Bears within three points. On the following series, the Vikings responded when Teddy Bridgewater escaped a blitz to throw a pass to Jerick McMcKinnon, who beat Shea McClellin to score on the 17-yard play. To start the second half, the Bears attempted an onside kick, and Sherrick McManis recovered. However, after three plays, Brian Robison sacked and stripped Jay Cutler, recovering the fumble; Minnesota took advantage with Stefon Diggs beating Alan Ball to score on the 33-yard touchdown. The Bears decreased the margin to two touchdowns when Robbie Gould kicked a 51-yard field goal; the next three consecutive drives concluded with punts. Afterwards, Cutler's screen pass to Matt Forte was intercepted by Justin Trattou, and the Vikings capitalized on the turnover with Bridgewater's 12-yard touchdown run, though the Bears retaliated with Cutler's four-yard touchdown pass to Forte. The Bears attempted another onside kick, but failed, and the Vikings later scored again on Zach Line's four-yard touchdown. With 1:50 left in the game, the Bears drove as far as the Vikings' 28-yard line, but time expired.

The loss dropped the Bears to 5–9 and officially eliminated them from playoff contention. Cutler's touchdown pass to Jeffery was his 200th career touchdown pass, while the onside kick attempted at the start of the third quarter was Gould's first successful kick in his eleven-year career with the Bears.

Week 16: at Tampa Bay Buccaneers
The final road game of the season took place in week sixteen, when the Bears visited the Tampa Bay Buccaneers. In 55 all-time meetings, the Bears led the series 37–18, while also winning the most recent game in 2014 21–13 and the last game in Raymond James Stadium in 2005 by a score of 13–10. Jeff Joniak writes that the offense, taking on a defense guided by former Bears head coach Lovie Smith, had to "be patient", a philosophy that teams had used during Smith's tenure in Chicago; Smith's defenses force offenses to work with long series, followed by forcing a turnover. In 2015, the Bucs defense recorded 22 fumbles, 11 interceptions and 33 sacks, 7.5 of which are by defensive tackle Gerald McCoy. Another player that the Bucs defense featured was linebacker Lavonte David, who recorded 12 pass breakups, three interceptions, two sacks and a forced fumble in 2015. Tampa's defense also excelled in the run and passing games; in the former, the Bucs allowed the second-fewest average yards per carry with 3.3, while being ranked fifth in yards allowed after the catch. The Bucs also ranked eighth in yards per play. However, opposing quarterbacks were completing a league-high 69.2 percent of passes, while also throwing for a total of 28 touchdowns. The Bucs defense was also without linebacker Kwon Alexander, who ranked second in the team in tackles with 93, as he was suspended for drug use. On defense, the Bears took on rookie Jameis Winston, who recorded 3,422 passing yards and 20 touchdown passes in 2015. However, the Bucs receiving corps had 29 drops and a 7.9 drop percentage, the second-highest in the NFL. Chicago's run defense faced Doug Martin, who had averaged 5.1 yards per carry, 1,305 rushing yards and a league-best 2.4 yards per carry after contact. Alshon Jeffery, Bryce Callahan, Jacoby Glenn, Shea McClellin, Nick Becton, Tayo Fabuluje and Bruce Gaston were inactive.

The Bucs won the coin toss and deferred. The Bears opened the game with a hurry-up offense and gained a first down, but were eventually forced to punt. Tampa Bay also later punted, but regained the ball at the Bears' four-yard line after a blocked punt; Jeremiah George escaped LaRoy Reynolds to block Pat O'Donnell's punt and Howard Jones recovered. The Bucs converted the play into a four-yard touchdown run by Martin. Both teams later punted on their next drives, Jay Cutler's screen pass was deflected and intercepted by William Gholston, who returned the pick to the Bears' 15-yard line, but Jacquies Smith's facemask penalty nullified the play. Afterwards, Ka'Deem Carey scored on a one-yard touchdown run to tie the score. On Tampa's next drive, Martin was stripped by Harold Jones-Quartey, and the fumble was recovered by John Timu; the takeaway led to Robbie Gould's 26-yard field goal. The Bucs were later forced to punt again with two minutes left in the first half, and the Bears offense drove 40 yards to the nine, where Gould kicked a 27-yard field goal with eight seconds left. Winston kneeled to end the half. On the first drive of the second half, the Bucs scored when Winston threw a 50-yard touchdown pass to Charles Sims, who took advantage of Tracy Porter to score. Although the Bears punted on their next drive, they regained possession after Christian Jones and Lamarr Houston's blitz forced Winston to throw to Charles Sims, where Jones-Quartey pulled the ball away.The Bears eventually punted, but got the ball back when Pernell McPhee stripped Martin, with the fumble being recovered by Timu. On the first play of the fourth quarter, Cutler's play-action pass to Carey resulted in a one-yard touchdown. The Bucs punted on their next series, and Gould kicked a 50-yard field goal to increase the score to 23–14; Connor Barth later missed a 52-yard field goal wide left, leading to Gould's 39-yard field goal. With one second left in the game, Winston threw a 43-yard touchdown pas to Austin Seferian-Jenkins, and on the ensuing onside kick, Cameron Meredith recovered as time expired.

With the win, the Bears officially improved upon their 5–11 record from 2014. The three turnovers forced in the game was a best for the defense, while also tying the total in the last five games.

Week 17: vs. Detroit Lions
The Bears ended the regular season at home against the Lions; in Chicago, the Bears led the series 50–26–3. Jeff Joniak writes that the Bears offense had to hold off the blitz; in 2015, the Lions had 38 sacks, including 13.5 by defensive end Ezekiel Ansah, and ranked fourth in sack percentage, while recording the second-most negative plays in the NFL. In comparison, the Bears had the fewest negative plays in the league. Despite the frequency to blitz, the Lions only had eight sacks when doing so. Through the air, the Lions pass defense struggled, allowing a 30th-ranked passer rating of 101.7 and 30 touchdown passes while recording only interceptions. To excel, the Bears had to maintain the ball, as they were ranked sixth in the NFL in time of possession. On defense, the Bears took on a Lions offense that had improved under offensive coordinator Jim Bob Cooter after Joe Lombardi's firing, going from 18.6 points per game to 26.4 under Cooter. With Matthew Stafford, the Lions were one of eleven teams with over 4,000 yards, while also being ranked in the top ten with 30 touchdown passes. However, Stafford was sacked 40 times, while the rushing attack averaged only 84.5 yards per game and 3.8 yards per carry. Eddie Royal, Zach Miller, Hroniss Grasu, Jarvis Jenkins, Jacoby Glenn, Tayo Fabuluje and Terry Williams were inactive.

The Bears won the toss and elected to defer. On the first drive of the game, the Lions scored first when Harold Jones-Quartey slipped while covering and Stafford threw a nine-yard touchdown pass to Tim Wright. The Bears offense reached the Lions' five-yard line on their first possession, but Jay Cutler's pass to Cameron Meredith deflected off Nevin Lawson's helmet and was intercepted by James Ihedigbo. However, two consecutive sacks forced the Lions to punt. In the second quarter, after the Bears punted, Matt Prater attempted a 54-yard field goal, but missed wide right. The Bears eventually punted again, and the Lions reached the Bears' 35-yard line, but on 4th and 3, Stafford's pass for Calvin Johnson fell incomplete. Three plays later, the Lions regained possession of the ball when Ansah hit Cutler's arm as he threw to Marc Mariani, the pass being intercepted by Tahir Whitehead. Detroit converted the turnover into Prater's 59-yard field goal to end the first half. The Bears scored on their first drive of the second half with Robbie Gould's 49-yard field goal, and after Detroit punted, tied the score with Cutler's 34-yard touchdown pass to Josh Bellamy. Although the Lions scored with Stafford's 36-yard touchdown pass to Johnson, the Bears retaliated with Cutler's 23-yard score to Matt Forte; Detroit eventually responded with a one-yard touchdown by Eric Ebron. The Bears narrowed the score to 24-20 when Gould kicked a 34-yard field goal. The Lions punted again, and the Bears took over with 3:35 left in the game. Despite reaching the Lions' 37-yard line, Cutler was hit by Ansah while throwing to Deonte Thompson and was intercepted by Glover Quin. With less than two minutes left in the game, the Bears held the Lions to 3rd and 5, but Stafford's six-yard pass to Johnson gave the Lions a first down, where Stafford kneeled thrice to end the game.

Cutler threw multiple interceptions in a game for the first time in 2015, ending the game with three. Adding the two field goals from the game, Gould ended the season with 33 field goals, breaking his 2006 record for the most in franchise history by one.

Statistics
In comparison to their 2014 counterpart, the 2015 Bears were more competitive in games; in 2014, three of the worst losses were by 48, 28 and 21 points, while six of the 2015 team's losses were by less than a touchdown, two of which ended in overtime. The Bears ended the season 5–3 in away games, but won only once at home, the worst home record in team history. Additionally, the Bears were swept at home by division opponents for the first time since the NFL realignment in 2002.

The Bears struggled with injuries during the season; only four players started all sixteen games: Kyle Long, Matt Slauson, Adrian Amos and Kyle Fuller. In each of the sixteen games, there was a different starting lineup.

The offense improved from 2014, progressing from 21st overall to 18th. The unit also recorded 5,514 total net yards and 344.6 per game. The passing attack improved from 28th in yards per play to 12th. On third down, Chicago ranked sixth in efficiency after converting 42.5 percent into first downs. With 21 turnovers allowed (13th in the NFL), the Bears had the fewest since the introduction of the 16-game schedule in 1978. Also, the Bears were able to score at least 30 points twice, after not doing so in 2014. In the first and third quarters, the Bears scored only 41 and 45 points, respectively, but scored 125 and 124 in the second and fourth. However, with 20.9 points per game, the Bears ranked 23rd in the NFL in the category, while also scoring only 24 touchdowns on 50 red zone attempts for a 48 percent red zone efficiency, 27th in the league.

The Bears defense vastly improved in comparison to the previous two seasons; after allowing the two most points in franchise history in 2013 (478) and 2014 (442), the 2015 defense allowed 397, which ranked 20th in the league. The defense gained 26 places in the pass defense category to end the season fourth in the ranking. While the unit also allowed only 225 passing yards per game, the number is skewed due to opposing offenses' frequency to run the ball; Bears opponents passed 512, the fourth-least in the NFL. Yardage-wise, the defense allowed an average of 345.1, gaining 16 spots to finish 14th. Statistically, the Bears allowed 7.5 yards per pass and a 62.9 completion percentage, 20th- and 14th-ranked in the league, respectively. The pass defense also allowed a passer rating of 99.2 passer rating (26th), 31 touchdowns (25th), while recording only eight interceptions, the second-least in the NFL. In total, the Bears forced only 17 turnovers (28th-ranked), failing to record one in seven games, and twice in only two games. In the red zone, the Bears allowed 27 touchdowns and 14 field goals on 45 attempts (60 percent), which ranked 21st in the league. Meanwhile, the pass rush recorded 35 sacks (22nd in the NFL), 20 of which occurred in the last seven games of the year, the seventh-most in the league.

Offense
Despite his receiving unit being plagued by injuries, Jay Cutler ended the season with 3,629 passing yards, 21 touchdowns, 11 interceptions and career highs in passer rating (92.3) and completion percentage (64.4). The eleven interceptions were the lowest in his career and resulted in an interception percentage of 2.3, the lowest in a season when he has started at least 12 games. The 21 touchdowns were his second-most since 2011 and the 3,629 yards were the third-most in his career. On third down, Cutler had a 103.2 passer rating (fourth in the NFL) after completing 91 of 141 passes for 1,242 yards, seven touchdowns and two interceptions. With five lost fumbles, Cutler had a total of sixteen turnovers in 2015, eight fewer than in 2014. In his lone start against the Seahawks, Jimmy Clausen completed 9 of 17 passes for 63 yards, and including sacks, recorded 48 net passing yards, the second time since the 1990 season that the Bears had less than 50 net yards passing. The Bears ended the year with 228.9 passing yards per game, ranked 23rd in the league. The quarterbacking group ended the season with a combined 63.9 completion percentage and 2.3 interception percentage, both of which ranked third in team history, along with 3,843 gross passing yards and a 42.5 third down percenage (fourth), 3,660 net passing yards (fifth), along with 5,514 total net yards and a 89.7 passer rating (sixth).

Spearheaded by the running back trio of Matt Forte, Jeremy Langford and Ka'Deem Carey, the Bears rushing attack ended the season sixth in rushing attempts with 469 and 11th in total rushing yards with 1,851. The group also ranked 11th in the league in rushing yards per game with 115.7. Forte led the three in attempts (218), yards (898) and yards per attempt (4.1) despite not playing in three due to injury, while Langford had the most touchdowns with six. Playing in eleven games, Carey scored twice on 43 attempts.

Chicago's top four receivers (Alshon Jeffery, Kevin White, Eddie Royal and Marquess Wilson) missed a combined 35 of 64 games. Jeffery, who never played four consecutive games in 2015, recorded 54 receptions for 807 yards and four touchdowns, while Zach Miller led the team in receiving touchdowns with five. Without the four, the Bears relied on Marc Mariani, Joshua Bellamy, Cameron Meredith and Deonte Thompson. Mariani recorded 22 receptions for 300 yards, while excelling on third down, recording eleven catches that resulted in first downs. Tight ends Martellus Bennett and Zach Miller also suffered injuries that led to them missing games; the former scored three times in eleven games, while the latter led the Bears in touchdowns with five.

The offensive line was frequently shuffled due to injuries, with left guard Matt Slauson playing some games at center and right guard Kyle Long moving to tackle. The former alternated between guard and center during the season, playing weeks seven to nine and sixteen at center. At left tackle, second-year player Charles Leno, Jr. started 13 games after taking over for an injured Jermon Bushrod; Gase stated, "He had a little bit of a rough start, but he just kept working and then when he got the opportunity at left tackle, he took full advantage of it."

Defense
On the line, rookie Eddie Goldman played fifteen games, recording 39 tackles and six tackles for a loss (TFLs), while being ranked fourth among rookies with 4.5 sacks. Other defensive linemen who contributed are Jarvis Jenkins, Will Sutton and Mitch Unrein. In fifteen starts, Jenkins recorded a career-best 32 tackles, four sacks and six TFLs. Sutton had 37 tackles and two TFLs, while Unrein, who also played as a fullback, had 32 tackles, two TFLs and a sack.

Christian Jones led the team in combined tackles with 87. Outside linebackers Lamarr Houston (8), Willie Young (6.5) and Pernell McPhee (6) recorded a combined 20.5 sacks, becoming one of only five defensive trios with at least six sacks per player in 2015. Houston, coming off a season-ending ACL injury in 2014, converted from defensive end to outside linebacker; he did not play much during the early portion of the season until Jared Allen was traded. He played only four snaps against the Vikings, but recorded 28 tackles, five sacks and six TFLs in from week nine to fourteen. In the final nine games, he had seven sacks, the sixth-most in that stretch. Young, who also switched from DE to OLB, recorded a sack in five consecutive games (weeks eleven to fifteen), the third player in franchise history to do so after Steve McMichael and Brian Urlacher. In the first seven games of 2015, McPhee recorded five sacks, 42 tackles and seven TFLs, while Sam Acho had 60 tackles, three TFLS, a forced fumble and a fumble recovery. Meanwhile, inside linebackers Christian Jones and Shea McClellin had the second- and third-most tackles for the Bears with 96 and 96, respectively. Rookie John Timu, who had been on special teams and the practice squad until becoming a starter for the final three games, recorded 25 tackles and two fumble recoveries.

For the cornerbacks, of the eight interceptions, Kyle Fuller led the Bears with two. Rookie Harold Jones-Quartey had an interception against the Buccaneers, the lone red zone turnover by the Bears in 2015. Tracy Porter led the team in pass breakups with 22, while also becoming the first player to break up four of Aaron Rodgers' passes in a game, doing so in week twelve. Rookie safety Adrian Amos recorded a team-high 108 tackles after starting every game; Amos also had a sack and four pass breakups. Antrel Rolle, who played in only seven games in 2015 due to ankle and knee injuries, had 45 tackles. In his place, Chris Prosinski and Harold Jones-Quartey emerged. In his first start against Denver, despite allowing a 48-yard touchdown on the first drive of the game, Prosinski ended the game with six tackles and a sack. The following week, he led the team in tackles with nine, while also recording his first career forced fumble. Jones-Quartey, who first played against Oakland and was benched after the Detroit game, excelled in his return against Tampa Bay, forcing two turnovers.

Special teams
Robbie Gould ended the season with 33 of 39 field goals converted for an 84.6 percentage, 19th in the league, while leading the Bears in scoring with 127 points. Despite his consistency, Gould struggled during the later portion of the season, missing two field goals against the 49ers and a potential game-tying kick against the Redskins. Pat O'Donnell punted 70 times for 3097 yards in 2015, 28 of which landed in the red zone with only four touchbacks. He ended the year with a net punting average of 39.6, which ranked 20th in the NFL. In his lone start with the Bears, Spencer Lanning punted three times for 156 yards with a net average of 35.7.

On punt returns, Marc Mariani averaged 6.6 yards on 29 attempts with his longest being a 20-yard return. The longest was a 65-yard touchdown by Bryce Callahan against the 49ers, which was eventually nullified by a holding penalty. The group ended the year with a 7.8 yard return average, 20th in the league. For kickoffs, the Bears finished with an average of 27 yards, which ranked third in the NFL. Mariani averaged 26.1 yards on 16 returns, while Deonte Thompson averaged 29.2 yards on 14 attempts, with his best being a 74-yard return. Thompson's average is the second-best in the league among players with at least ten attempts.

The kickoff team started the year on a sour note after allowing returns of 105 and 108 yards against the Cardinals and Seahawks, but ended the year by forcing opponents to return an average of 25.2 yards, which ranked 21st in the league. For the punting unit, despite allowing 64- and 65-yard returns against Seattle and Minnesota, opposing return teams recorded 7.5 yards, 14th in the NFL. Sherrick McManis led the special teams unit in tackles with eleven.

Awards and records
On December 22, the rosters for the 2016 Pro Bowl were announced, with no Bears players making it for the first time since 1998. However, on January 14, 2016, Kyle Long was named as an alternate for Eagles lineman Jason Peters, marking his third consecutive Pro Bowl appearance. On January 7, Eddie Goldman and Adrian Amos were named to Mel Kiper, Jr.'s All-Rookie Team and the Pro Football Writers of America's All-Rookie Team.

At the start of the season, Robbie Gould's first field goal marked the 244th of his career, surpassing Kevin Butler for the most in franchise history. Against the Chargers, Jay Cutler threw his 138th career touchdown pass to Martellus Bennett, breaking a tie with Sid Luckman; the record had stood since September 17, 1950.
