The Trojans got more bad news at their scrimmage Monday night at the Coliseum. USC's starting center Kristofer O'Dowd, the team's best offensive lineman, went down on the first drive and needed to be helped off the field.
Given the buzz building around true freshman QB Matt Barkley, it's not a stretch to think USC's first-team quarterback Aaron Corp was pretty anxious as he sat out the Trojans' Tuesday night practice with a swollen left knee.
Kevin Ellison, USC's second-leading tackler, suffered a torn meniscus Thursday at the Trojans' practice. The senior strong safety said late Thursday night that he's been told he'll be out two to four weeks.
After USC's Wednesday night practice, coach Pete Carroll pronounced star middle linebacker Rey Maualuga "full go" and said he would start and Brian Cushing would shift over from middle linebacker back to his strongside linebacker spot.
