ASSOCIATED PRESS FILE- In this Sept. 12, 2010, file photo, Detroit Lions wide receiver Calvin Johnson (81) catches a pass in the end zone over Chicago Bears cornerback Zackary Bowman late in the second half of an NFL football game in Chicago. Johnson makes a leaping grab in the end zone for what appeared to be a 25-yard TD catch that puts the Lions in the lead with 31 seconds left. But when he completes rolling over, he leaves the ball on the ground and begins celebrating. The official ruling is the player has to "maintain possession of the ball throughout the entire process of the catch." The Bears won 19-14.
