I am talking about during the game and letting the Referee announce it; saying the play was reviewed and the call stands. It was the third time a close went against the Cards and this time they could not throw the red flag! At 2:01 on the clock the Cards can at 15 seconds they can not!
The officials in the replay booth alert the on-field referee if they need to stop action so that they can review something.
As has been pointed out numerous times, the replay official saw that it was an obvious fumble. The defender knocked the ball loose well before the QB made any attempt to move his arm forward. No control means no pass is possible. No need to stop action to review it.
End of story.
