UCLA running back Jordon James is doubtful for next Saturday’s game against Cal after suffering an ankle injury during the Bruins’ 34-27 win at Utah yesterday. The junior’s X-rays were negative, head coach Jim Mora said, but remains in a walking boot to keep pressure off the ankle.

Redshirt freshman Paul Perkins is expected to start in place of James, who entered Thursday as the nation’s fifth-leading rusher. He carried the ball 12 times for 39 yards and a touchdown before leaving the game, dropping him outside the top 15.

Perkins performed well against the Utes, rushing for 92 yards on 16 touches. Steve Manfro, Malcolm Jones and Damien Thigpen will play reserve roles.
