1. When the quarterback or a teammate, makes an apparent attempt to pass at any time before he or a teammate is tackled, steps out of bounds, or fumbles behind or at the statistical line of scrimmage, the play is scored as a sack and any yards lost attempting to pass. (Should he advance the ball across the statistical line of scrimmage, it is a rushing play.)
2. When the quarterback is tackled or, after gaining possession of the snap, he fumbles or falls down, while retreating to his normal passing position, it shall be scored as a sack and yards lost attempting to pass, even though he may not have assumed a passing position. EXCEPTION: When a player retreating to passing position fumbles behind the line of scrimmage but recovers the fumble himself and runs beyond the statistical line of scrimmage, the play is scored as a rushing play, a fumble, and an own recovery.
