1999 NFL season

The 1999 NFL season was the 80th regular season of the National Football League. The Cleveland Browns returned to the field for the first time since the 1995 season. Also, the Tennessee Oilers changed its name to Tennessee Titans, and the league retired the name "Oilers" – a first in league history.

The return of the Browns gave the league 31 teams (the first time since about 1966 that the NFL had an odd number of teams). As a result, the NFL was forced to give at least one team a bye each week. Previously, the league never gave a club the week off during the first two weeks or last seven weeks of the season (the only exception being in 1992, when the Miami Dolphins and New England Patriots had a bye in week 1, as Hurricane Andrew forced the postponement of their season-opening game to October 18, when their byes were originally scheduled). Under this new system, for ten weeks of the season (Week #1 to Week #2, and Week #10 to Week #17), exactly one team was scheduled a bye; for seven weeks of the season (Week #3 to Week #9), three teams sat out. This format would continue for the next two seasons until the Houston Texans joined the NFL in 2002 and returned the league to an even number of teams.

The start of the 1999 NFL Season was pushed back one week and started the weekend after Labor Day, a change from the previous seasons. Due to the Y2K concerns, the NFL did not want to hold the opening round of the playoffs on Saturday January 1, 2000, and did not want teams traveling on that day. Week 17 games were held on January 2, 2000, and the opening round of the playoff would be scheduled for January 8–9. The bye week before the Super Bowl was removed to accommodate the one-week adjustment. The start of the season after Labor Day would become a regular fixture for future seasons, beginning in 2001.

The St. Louis Rams, who had a losing record for each of the past nine seasons, surprised the entire league by defeating the Tennessee Titans in Super Bowl XXXIV.

Major rule changes

 * Clipping is now illegal around the line of scrimmage just as it is on the rest of the field.
 * A new instant replay system (different from the one used from 1986 to 1991) is adopted to aid officiating. The system mirrors a method used by the defunct USFL in 1985:
 * In each game, each team has two challenges that will start a review. Each challenge will require the use of a team's timeout. If the challenge is successful, the timeout is restored.
 * Inside of two minutes of each half, and during all overtime periods, all reviews will be initiated by a Replay Assistant. The Replay Assistant has an unlimited number of reviews, regardless of how many timeouts each team has left. And no timeout will be charged for any review by the Replay Assistant.
 * All replay reviews will be conducted by the referee on a field-level monitor. A decision will be reversed only when there is indisputable visual evidence to overturn the call. The referee has 90 seconds to review the play.
 * The officials will be notified of a replay request or challenge via a specialized electronic pager with a vibrating alert. Each head coach would also have a red flag to use as a backup to get the attention of the officials to challenge a play.
 * The replay system will only cover the following situations:
 * Scoring plays
 * Pass complete/incomplete/intercepted
 * Runner/receiver out of bounds
 * Recovery of a loose ball in or out of bounds
 * Touching of a forward pass, either by an ineligible receiver or a defensive player
 * Quarterback pass or fumble
 * Illegal forward pass
 * Forward or backward pass
 * Runner ruled not down by contact
 * Forward progress in regard to a first down
 * Touching of a kick
 * Too many men on the field

The league also added the following then-minor rule change that became significant in the playoffs a few years later:
 * When a Team A player is holding the ball to pass it forward, any intentional forward movement of his hand starts a forward pass, even if the player loses possession of the ball as he is attempting to tuck it back toward his body. Also, if the player has tucked the ball into his body and then loses possession, it is a fumble.

This new interpretation of a forward pass would later be commonly known as the "Tuck Rule".

Music City Miracle
The Music City Miracle is a famous play in the NFL Wild Card Playoffs involving the Tennessee Titans and Buffalo Bills that took place on January 8, 2000 (following the 1999 regular season) at Adelphia Coliseum in Nashville, Tennessee.

Going into the game, Bills coach Wade Phillips created a stir by starting quarterback Rob Johnson, rather than Doug Flutie, who had started 15 games, and who had led the team to the playoffs. Late in the fourth quarter, the stage was set for an exciting finish. Tennessee received the ball with 6:15 remaining. Titans receiver Isaac Byrd's 16-yard punt return and five carries from Eddie George for 17 yards set up a wobbly 36-yard field goal by Del Greco. The Titans took a 15–13 lead with 1:48 to go. On the ensuing drive, with no timeouts remaining, Bills quarterback Johnson led the Bills on a five-play, 37-yard drive to the Titans' 24 yard line. On the last two plays from scrimmage, Johnson played with only one shoe on, as he had lost one and had no time to put it back on, with the clock running out. With only 16 seconds remaining in the game, Steve Christie, the Bills' kicker, made a 41-yard field goal to put Buffalo in the lead, 16–15.

Moments later, Christie kicked off, and Titans player Lorenzo Neal received. Neal handed the ball off to Titans tight end Frank Wycheck, who then lateraled the ball across the field to another Titans player, Kevin Dyson, who then ran down the sidelines for a 75-yard touchdown. The play was named Home Run Throwback by the Titans and was developed by Special Teams Coordinator Alan Lowry. Per the instant replay rules, the play was reviewed by referee Phil Luckett since it was uncertain if the ball had been a forward pass, which is illegal on a kickoff return. However, the call on the field was upheld as a touchdown, and the Titans won the game 22–16. After the game, however, many Bills players and fans continued to insist that it was indeed an illegal forward pass. With this play, the Titans were able to get to the Super Bowl.
