During the offseason, the former Texas Longhorns signal caller had planned to take two weeks off for his honeymoon. But, according to Simms, he had to come back two days early because Gruden wouldn't stop calling him.
After spending the past nine seasons as a commentator for ESPN's 'Monday Night Football,' Gruden announced he would return to the sidelines as the head coach of the Oakland Raiders.
He previously served in that position from 1998 until early 2002.
