In
gridiron football, a
turnover occurs when the team with the ball loses possession of the ball without kicking it, which is then gained by the other team. In
American football, the two events that are officially classified as "turnovers" are
fumbles (accidental physical loss of a live ball a player has possession of) or
interceptions (passes intended for a member of the passing team, but caught by a member of the opposing team).
