Mike Vrabel says he will have assistant head coach/defensive line coach Terrell Williams handle the head coach duties in the Tennessee Titans' preseason opener against the Chicago Bears on Saturday.

"I think this is a great opportunity for him and for us and for everybody involved," Vrabel said. "Big T [Williams] will handle that and [defensive assistant] Clint McMillan will handle the defensive line. That will start on Friday."

Williams will handle in-game decisions, but Vrabel will still be with the team on the sideline.
