 Both teams then attempt to catch the ball.The player who recovers the ball may run while holding the ball, or throw the ball to a teammate, so long as the throw is not forward.Play stops when the ball carrier's knee, elbow, or any other body part aside from the feet and hands, is forced to the ground (a "tackle"); when a touchdown (see below) or a field goal is scored; when the ball leaves the playing area by any means (being carried, thrown, or fumbled out of bounds); or when the ball carrier is in a standing position but can no longer move.
