Ousted UCLA football Coach Karl Dorrell has decided not to coach the Bruins when they play BYU in the Las Vegas Bowl. Defensive Coordinator DeWayne Walker will serve as interim coach for the Dec. 22 game. When UCLA Athletic Director Dan Guerrero fired Dorrell on Monday, Guerrero told Dorrell he could coach the team in the Dec. 22 game if he wished. "I appreciate the opportunity to coach in the bowl game, but I have decided it is in the best interests of the program for me to decline that opportunity," Dorrell said Tuesday. "The game should be about the players, especially the seniors." "While I would love to take the field with these young men one last time, I felt that my situation would take the focus away from our players and their efforts, and that's the last thing I would want to do."
