Phillips, 63, replaces Frank Bush who was fired at the end of the regular season and returns to the NFL after he was sacked by the Cowboys following a 1-7 start to the year.

The Texas native played and coached at the University of Houston and was also an assistant to his father, Bum Phillips, at the city's earlier NFL franchise, the Houston Oilers.
