USC’s Adoree’ Jackson practices; Justin Davis, Claude Pelon return from injuries

USC cornerback Adoree’ Jackson, who suffered an abdominal strain against Arkansas State, practiced on Tuesday, and tailback Justin Davis and defensive lineman Claude Pelon returned from injuries, as the Trojans began preparations for Saturday’s game against Idaho.

Jackson was held out of the Arkansas State game last Saturday after suffering the injury on a first-quarter punt return.

He performed most drills Tuesday but was held out of the final scrimmage drill.

“We’re going to monitor him closely,” Coach Steve Sarkisian said. “Anytime you come out of a game and you can’t finish a ballgame we’re going to treat it very seriously, but I think he’ll be fine for Saturday.”

Davis returned from a rib injury that had kept him out of practice for three weeks. He appears on track to play against Idaho.

“We have to put him in the game -- it’s the only way you get over some of that stuff,” Sarkisian said. “A lot of time, with injuries, as much as it is physical, it’s mental.

“He’s physically cleared to play. Now he’s got to get over the mental hurdle.”

Pelon had arthroscopic knee surgery last month. Sarkisian said the senior “had to work a little bit of rust off,” but looked good. If he recovers from practice each day this week, “all signs are pointing to him playing Saturday,” Sarkisian said.
