The Fifth Down Game is the name of a college football game that included a play that the crew officiating the game permitted to occur in error. That play enabled the Colorado Buffaloes to defeat the Missouri Tigers by scoring a touchdown on the last play of their game on October 6, 1990. The ensuing controversy cast doubt on Colorado's claim to NCAADivision I-A's 1990 national championship. It has been called one of the top memorable moments and blunders in college football history.[1][2]
