Incomplete pass

An incomplete pass is a term in gridiron football which means that a legal forward pass is not successfully caught by an eligible offensive player within the field of play. An incomplete pass can occur if (1) the ball hits the ground in the field of play before a player on either team gains possession; (2) the ball is caught by a player on either team who, at the moment of possession is out of bounds; or (3) the ball is thrown outside the field of play. An incomplete pass causes the down to advance by one and the offensive team gains no yards. The game clock is stopped.
