Notes off Thursday's practice that won't make into our other coverage off the session:
USC coach Lane Kiffin seems pleased with his offensive line, which has taken shape this spring with Aundrey Walker manning the left tackle spot and Marcus Martin, Khaled Holmes, John Martinez and Kevin Graf slotting next to him in order. We'll have more on Walker's status later Thursday.
Injury report: Tight end Randall Telfer (hamstring) returned to practice before re-aggravating the hamstring. Safety Drew McAllister (hip), running back Buck Allen (hamstring) and tight end Junior Pomee (foot) missed practice with their respective injuries. Linebacker Marquis Simmons (undisclosed) exited practice early and receiver De'Von Flournoy (undisclosed) was limited. Quarterback Max Wittek (foot) didn't participate in the 11-on-11 drills but is expected to be ready to go for Saturday's scrimmage.
In more positive news, tight end Xavier Grimble returned to practice for the first time in a month. He hurt his toe during the Trojans' first Tuesday practice of the spring and had been rehabbing it since. His presence gave the Trojans their first healthy tight end for a full practice in weeks.
Receiver Marqise Lee got into a bit of a shoving match with some of his defensive teammates following a route. He minimized the incident after the practice, saying he did it to raise the energy level of the practice. "You know how teams are," Lee said. "We were going after it and got a little bit too hyped and started pushing each other."
Quarterback Cody Kessler threw his first interception of the spring to linebacker Tony Burnett. We'll have more on this Friday, including Kessler's reaction to breaking up his no-hitter, as the Trojans' coaches were calling it.
Final notes: Saturday's 11 a.m. scrimmage at the Coliseum is open to the public, as previously reported. ...Matt Barkley was picked off by cornerback Isiah Wiley for his eighth interception of the spring. ...Several Marines from the Wounded Warriors West Battalion at Camp Pendleton visited practice and spoke to Kiffin, Barkley and Holmes afterward.
