The 1993 NFL season was the 74th regular season of the National Football League. It was the only season in league history where all NFL teams played their 16-game schedule over a span of 18 weeks. After the success of expanding the regular season to a period of 17 weeks in 1990, the league hoped this new schedule would generate even more revenue. This was also done to avoid scheduling playoff games on January 1 and competing with college football bowl games. However, teams felt that having two weeks off during the regular season was too disruptive for their weekly routines, and thus it reverted to 17 weeks immediately after the season ended.
When new TV contracts were signed in December 1993, CBS lost their rights to broadcasting NFC games to the then seven-year old Fox Network, which took effect next season.
The season ended with Super Bowl XXVIII when the Dallas Cowboys defeated the Buffalo Bills 30–13 for the second consecutive season at the Georgia Dome. This remains the only time both Super Bowl participants have been the same in successive seasons. The Cowboys became the first team to win a Super Bowl after losing their first two regular season games. This game also marked the fourth consecutive Super Bowl loss by the Bills.
The Play Clock (the time limit the offensive team has to snap the ball between plays) was reduced from 45 seconds to 40 seconds (the time interval after time outs and other administrative stoppages remained 25 seconds).
Ineligible receiver down field prior to a forward pass foul was added.
The passer could now legally throw a pass away, without any offensive player having a chance to catch the ball, as long as they are out of the pocket and the ball lands beyond the line of scrimmage.
The player taking a snap from the center, upon receiving the ball, can immediately throw the football directly into the ground to stop the game clock.
The NFL added an extra (second) bye week into the season for each team. The extra bye week was removed in 1994.
