Earnest Alexander Byner (born September 15, 1962) is an American football coach and former running back. He is famous for one well known mistake while playing with the Cleveland Browns. While playing against the Denver Broncos in a 1986 playoff game, Byner fumbled at the Denver one yard line, which led to a Broncos victory. The play was called "The Fumble." Byner immediately became an assistant coach after his playing days were over.
