Here are notes from Thursday's practice that won't make it into our other coverage from the session, the last official practice until August for the Trojans. Of course, USC scrimmages on Saturday at the Coliseum in the annual spring game, which starts at 1:30 p.m.
Running back Buck Allen took the most snaps out of the backfield he has taken all spring and showed improvement as he returns from a strained right hamstring that bothered him for nearly a month. He, Curtis McNeal and D.J. Morgan are again the Trojans' only three scholarship running backs with Tre Madden now out for the year.
Cornerback Brian Baucham continued his strong play toward the end of the spring with an interception on a tipped pass off a Max Wittek-to-Junior Pomee throw. Baucham has put himself into the competition for the third corner spot.
Injury report: Receiver Victor Blackwell (foot) did not participate in practice but could return for Saturday's scrimmage, Lane Kiffin said. Kiffin also said cornerback Ryan Henderson could play Saturday. Receiver George Farmer (hamstring) did only individual work, as has been the case since the first week of the spring. It seems unlikely he will participate in the scrimmage portion of Saturday's session. Officially out for Saturday are tight end Randall Telfer (hamstring) and linebackers Dallas Kelley and Marquis Simmons.
Among the recruits at practice were high-profile 2013 defensive tackle Kenny Bigelow, the first player to commit to the Trojans' next class, and 2015 quarterback David Sills, who was also there Tuesday. Signee Jabari Ruffin was also in attendance and spent some time with linebackers coach Scottie Hazelton after practice.
Final notes: USC will not tackle in Saturday's scrimmage to preserve players' health over the offseason, Kiffin said. We'll have more on that on Friday. ... Tight end Christian Thomas underwent surgery this week on his ailing hip and is expected to be ready for fall camp. ...Defensive back Josh Shaw had his hardship waiver claim granted by the NCAA on Thursday and will be eligible to play for the Trojans in 2012. We'll have more on what that means for USC later.
