Matt Barkley likely in against UCLA

LOS ANGELES -- USC quarterback Matt Barkley suited up for practice Tuesday and likely will start Saturday against rival UCLA.

Barkley was held out of Saturday's 20-16 loss to Notre Dame with a high-ankle sprain, but said afterward there was "no doubt" he would play this week.

In the early part of Tuesday's practice, Barkley held a play sheet while backup quarterback Mitch Mustain worked with the first-unit offense. Afterward, Barkley jogged to the other practice field without a noticeable limp and played catch with Mustain.

Coach Lane Kiffin said on 710 ESPN Tuesday that he expects Barkley to play.

"I think he's going to play because I think if it's anywhere close he's just going to make himself play, regardless," Kiffin said.

A sophomore, Barkley has completed 63 percent of his passes for 2,593 yards and 25 touchdowns this season. He has thrown 10 interceptions. Last season, he was the first true freshman to start a season opener at quarterback for USC.

Mustain completed 20 of his 37 passes for 177 yards and an interception against Notre Dame.
