2001 NFL season

Mike Pereira became the league's Director of Officiating, succeeding Jerry Seeman, who had served the role since 1991.

Bill Leavy and Terry McAulay were promoted to referee. Phil Luckett returned to back judge, while another officiating crew was added in 2001 in preparation for the Houston Texans expansion team, the league's 32nd franchise, in 2002.

Due to labor dispute, the regular NFL officials were locked out prior to the final week of the preseason. Replacement officials who had worked in college football or the Arena Football League officiated NFL games during the last preseason week and the first week of the regular season. A deal was eventually reached before play resumed after the September 11 attacks.

• Fumble recoveries will be awarded at the spot of the recovery, not where the player’s momentum carries him. This change was passed in response to two regular season games in 2000, Atlanta Falcons–Carolina Panthers[3] and Oakland Raiders–Seattle Seahawks,[4] in which a safety was awarded when a defensive player’s momentum in recovering a fumble carried him into his own end zone.
• Taunting rules and roughing the passer will be strictly enforced.

Following a pattern set in 1999, the first week of the season was permanently moved to the weekend following Labor Day. With Super Bowls XXXVI-XXXVII already scheduled for fixed dates, the league initially decided to eliminate the Super Bowl bye weeks for 2001 and 2002 to adjust.

In the wake of the September 11 attacks, the games originally scheduled for September 16 and 17 were postponed and rescheduled to the weekend of January 6 and 7. In order to retain the full playoff format, all playoff games, including the Super Bowl, were rescheduled one week later. The season-ending Pro Bowl was also moved to one week later. This was the last season in which each conference had three divisions, as the conferences would be realigned to four divisions for the 2002 NFL season.

Canceling the games scheduled for September 16 and 17 was considered and rejected since it would have canceled a home game for about half the teams (15 of 31). It would have also resulted in an unequal number of games played: September 16 and 17 was to have been a bye for the San Diego Chargers, so that team would still have played 16 games that season and each of the other teams would have played only 15 games (the Chargers ultimately finished 5–11, making any competitive advantages to playing an extra game irrelevant).

New England at Carolina in week 17, January 6, 2002

As a result of rescheduling Week 2 as Week 17, the Pittsburgh Steelers ended up not playing a home game for the entire month of September (their only home game during that month was originally scheduled for September 16). The ESPN Sunday Night Football game for that week was also changed. It was originally scheduled to be Cleveland at Pittsburgh, but it was replaced with Philadelphia at Tampa Bay, which was seen as a more interesting matchup. Ironically, the Eagles and Buccaneers would both rest their starters that night, and would meet one week later in the playoffs. In recognition of this, when NBC began airing Sunday Night Football in 2006, there would be no game initially scheduled for Weeks 11 to 17 – a game initially scheduled in the afternoon would be moved to the primetime slot, without stripping any teams of a primetime appearance. This way of “flexible scheduling” would not be utilized at all in 2007, and since 2008, it is only utilized in the final week.

The games that eventually made up Week 17 marked the latest regular season games to be played during what is traditionally defined as the "NFL season" (under the current format, the regular season cannot end later than January 3 in any given year).

Another scheduling change took place in October, when the Dallas at Oakland game was moved from October 21 to October 7 to accommodate a possible Oakland Athletics home playoff game on the October 21. The rescheduling ended up being unnecessary as the Athletics would not make it past the Division Series round.
