Outside linebackers Dion Bailey and Hayes Pullard are both cleared for competition and will play Saturday against Washington.
Bailey, who suffered a concussion two weeks ago against Stanford, missed last Friday's game against Colorado while waiting to be cleared. Pullard played against the Buffaloes but injured his neck in the second half and sat out of Monday's practice with unexpected soreness.
USC coach Lane Kiffin had said Wednesday that he had significant hopes both players would be able to suit up.
In other injury news, defensive tackle DaJohn Harris (ankle) and cornerback Torin Harris (shoulder) will both be game-time decisions, Kiffin said.
DaJohn Harris' injury is new, turning up just this week. Torin Harris has been out since the Arizona State game in late September.
