Every fan loves extra football, but that concept didn't exist in the NFL until 1974. That year, the NFL implemented overtime in the regular season.
In regular-season play, the league has always capped overtime at one extra period. In the postseason, teams play as long as it takes for playoff glory.
Six playoff games in NFL history have required two overtime periods to decide a winner. Take a look at the longest NFL games by actual game clock time (60 minutes of regulation plus the amount of time needed in overtime) below:
▪︎ 82 minutes, 40 seconds - Miami Dolphins def. Kansas City Chiefs 27-24 in 1971 AFC Divisional Round on Dec. 25, 1971
