Al Riveron, the NFL's senior vice president of officiating, has defended a controversial overturned call against Chicago Bears tight end Zach Miller on the play in which he dislocated his knee against the New Orleans Saints in Week 8.
In a video of the play released by the NFL Football Operations website, Riveron explained the ball was loose when Miller initially caught it and had to regain full control for it to be ruled a touchdown.
Riveron went on to say when Miller hits the ground, the ball comes loose again and hits the ground.
