PASADENA ( – USC senior quarterback Matt Barkley has reportedly separated his right shoulder in loss to the UCLA Bruins Saturday at the Rose Bowl.

With 2:25 left in the game, Barkley landed on his right shoulder after UCLA linebacker Anthony Barr sacked him viciously to the ground.

“I thought I fought as hard as I could’ve fought,” Barkley said. “I went down fighting. Plays were there, plays weren’t there. There were times where I felt like I could’ve broken the game open. It just didn’t happen.

The NFL prospect left the stadium with his right arm in a sling, according to ESPN Radio.

Barkley, who returned for his senior season, threw for 301 yards and three touchdowns, but was intercepted twice in USC’s third loss in four games.

Lane Kiffin did not comment on the injury.

Max Wittek replaced Barkley.
