The Tuscaloosa (Ala.) News reported the news Tuesday afternoon.
Alabama hired former UCF interim coach/offensive coordinator Brent Key as the interior offensive line coach Monday, with Mario Cristobal moving from offensive line coach to tackles and tight end coach. Williams had been tight ends coach and special teams coordinator.
Williams has been at Alabama since 2008, and he also worked with Saban at Michigan State, LSU and with the Miami Dolphins.
