Around the NFL Week 13

Item 1: Player Going to the Ground. If a player goes to the ground in the act of catching a pass (with or without contact by an opponent), he must maintain control of the ball throughout the process of contacting the ground, whether in the field of play or the end zone. If he loses control of the ball, and the ball touches the ground before he regains control,
the pass is incomplete. If he regains control prior to the ball touching the ground, the pass is complete.

I copied this right out of the rule book, maybe i saw the play incorrectly but to me he didnt complete the catch to the ground.
