No disrespect there Mr. Perdogg, but the officials on the field are not responsible for the play clock. It was the Dallas Cowboys play clock operator who made the mistake. They hit the 25 sec. button instead of 40 sec. The officials could have corrected it if they had noticed, but it wasn't brought to their attention.
I heard what DeweyFrank says here as well, the time keepers are separate from the Officials.
