Position Switch, Injury Updates

Tight end Christian Thomas is playing defensive end full time now because of the injury to Nick Perry. Thomas had a sack in last weekend's scrimmage and caught a 20-yard pass. USC had 14 scholarship players out today with injuries. Offensive tackle Butch Lewis said a hip specialist said he strained his groin and might Monday. Lane Kiffin said Lewis might need an injection before he comes back. Safety Drew McAllister's strained hip is a bigger problem and he might need to tough out the season and then undergo surgery, Kiffin said.
