Leaping in professional sports refers to a violation of NFL rules where a player on defense jumps in an attempt to block a field goal and lands on a fellow teammate. According to the rules, if a defensive player lines up more than one yard from the line of scrimmage, runs forward, jumps in the air in an attempt to block the kick, then lands on a teammate, this constitutes a leaping penalty. The penalty is also considered unsportsmanlike conduct, resulting in 15 yards (or half the distance to the goal, whichever is shorter) and an automatic first down.
