Final answer:
If the ball is beyond the neutral zone when it leaves the passer's hand on a forward pass, it is considered an illegal forward pass.
Step-by-step explanation:
If the ball is beyond the neutral zone when it leaves the passer's hand on a forward pass, it is considered an illegal forward pass. In American football, a forward pass must be thrown from behind the line of scrimmage and the ball must not cross the neutral zone before being thrown. If this rule is violated, it results in a penalty for the offensive team.
