The 2011Detroit Lionsseason was the franchise's 82nd season in the National Football League, their 78th as the Detroit Lions, the 10th playing its home games at Ford Field and the third year under head coach Jim Schwartz. With a regular season record of 10–6, the team improved on its 6–10 record from 2010, which is their third consecutive improved season. It was the Lions' first winning season since 2000 and first 10 win season since 1995. The Lions' 5–0 start was their best since 1956. With their win over the San Diego Chargers on December 24, the Lions clinched an NFC Wildcard spot in the postseason. After their loss to the Green Bay Packers in Week 17, it was determined the Lions would play the New Orleans Saints in the Wildcard round. It was their first playoff berth since 1999.
The Lions ran a pass-heavy offense in 2011. Quarterback Matthew Stafford's 663 passing attempts (41.4 attempts per game) led the league, and they only ran the ball on 33.8% of their plays, a league low. According to statistics site Football Outsiders, the Lions went into shotgun formation a league-leading 68% of offensive plays in 2011. Stafford became only the fourth quarterback to pass for 5,000 yards in a season, and his 5,038 yards passing are 5th-most in NFL history (though only 3rd in the 2011 NFL season).
On October 18, the Lions attempted to trade running back Jerome Harrison and an undisclosed pick in the 2013 NFL Draft to the Philadelphia Eagles for running back Ronnie Brown, but the deal was voided due after Harrison failed his Eagles physical with what Adam Schefter of ESPN reported was a then-undiagnosed brain tumor. Harrison had surgery on October 21 and was placed on the injured reserve list for the remainder of the season.
The same day, the Lions signed free agent running back Eldra Buckley to replace Harrison in the lineup. 
To start the season, the Lions traveled south to Tampa, Florida to take on the Tampa Bay Buccaneers. The Lions scored first in the first quarter with a 23-yard field goal by Jason Hanson.

The Lions responded with a 28-yard field goal. In the second quarter, Detroit took the lead with a 36-yard touchdown catch by Calvin Johnson, and later added more points when Tony Scheffler caught an 11-yard TD pass. Tampa Bay responded with a 31-yard field goal just before halftime. The second half was relatively quiet, with each team only scoring one touchdown. First, Detroit's Calvin Johnson caught a 1-yard pass in the third quarter. The game's final points came when Mike Williams of Tampa Bay caught a 5-yard pass.
