Buck-lateral is an American football play or a series of plays used in the Single-wing formation. Since the Single-Wing formation lost prominence by 1950, the football play referred to as the buck-lateral is almost gone from football's vocabulary. However, prior to this time, the buck-lateral play gave fullbacks the option to run, lateral, or hand off the ball to another player. Running the buck-lateral required an offensive scheme that needed the fullback to possess many specialized skills, as opposed to today's fullback who mainly blocks and carries the ball infrequently.
