The September 11, 2001 terrorist attacks led the league to postpone its September 16–17 games and play them a week after the scheduled conclusion of the regular season. This caused the playoffs and Super Bowl to be delayed by one week. This thus marked the first time in NFL history that the Super Bowl was played in February. No bye week was originally scheduled between the conference championships and the Super Bowl this season, so the NFL had to work diligently to get the final game in New Orleans rescheduled, including having alternative plans to host the Super Bowl in another city.
