Game-time updates: Notre Dame

We're just about set to go at the Coliseum for USC-Notre Dame.

Here are a couple of last-minute things worthy of an update before the Trojans attempt to top Notre Dame and extend their series winning streak to nine games:

  • Sophomore quarterback Matt Barkley, who suffered a left high-ankle sprain last week against Oregon State, will not start today's game, according to the pregame starting lineups announced on the Coliseum video board. In his place will be backup Mitch Mustain, who hasn't started a game since Nov. 4, 2006. That day, he started for Arkansas against South Carolina but lasted only one series, throwing an interception

  • More injury updates: Safety Jawanza Starling (hamstring) is dressed for the first time since the Arizona State game earlier this month, but he's still not starting. Redshirt junior Marshall Jones will join T.J. McDonald in the secondary for the third straight week. Torin Harris (shoulder) is not dressed and will not play, meaning the Trojans will either stick to nickel formations or play a walk-on as their fourth-courner in dime packages. Chris Galippo, who missed most of the Oregon State game because of a first-quarter concussion, is in the starting lineup at middle linebacker despite not practicing fully all week.

  • Right tackle Tyron Smith will not start at right tackle, with senior guard/tackle Butch Lewis announced in his place in the pregame starting lineups. Lewis lost his job as the starter at left guard two-plus weeks ago to Michael Reardon and hasn't started a game since but practiced a lot this week at right tackle. He started five games at the spot in 2008.
