I saw the Seahawk player knock the ball out of the end zone and wondered about it when I saw it. The Referees didn't call the penalty, which the rulebook states that if a defensive player bats a ball out of an endzone when it's on the ground - it goes back to the offense, half the distance to the goal. So the Seahawks won that game, but the ball should've been given to the Lions on the 1 yard line.
