This article is about the football game between the University of Colorado at Boulder and the University of Missouri. For the 1940 game between Cornell and Dartmouth, see
Fifth Down Game (1940).
The Fifth Down Game was a college football game on October 6, 1990, that included a play the crew officiating permitted in error. That play enabled the Colorado Buffaloes to defeat the Missouri Tigers by scoring a touchdown at the end of the game. The ensuing controversy cast doubt on Colorado's claim to Division I-A's 1990 national championship, which it went on to share with the Georgia Tech Yellow Jackets. It has been called one of the top memorable moments and blunders in college football history.
