Sophomore Aaron Corp may have entered USC's fall camp holding the No. 1 quarterback spot, but with a broken bone in his leg, it's entirely possible his entire career path has been altered.

After coach Pete Carroll said Corp needed to return by Tuesday, Corp has eased his way into 7-on-7 drills as he hopes to make a full return to battle true freshman Matt Barkley for the starting job.

With a game at Ohio State in the second week, USC can't afford to go to Columbus with uncertainty at the quarterback position. The Trojans boast three highly touted quarterback prospects in Corp, Barkley and Mitch Mustain, and Barkley has received plenty of praise for how he's run with the first team in Corp's absence.

Carroll is never afraid to play younger players, and after enrolling early, Barkley is probably as prepared as anyone to immediately step into a starting role.

Both guys will probably get a chance to play, but if Corp is not entirely ready, Barkley will get the call and will likely impress coaches with his play.

If that's the case, Corp could be out of luck. That's the problem with so many big-time prospects at the same position going to the same school, as one broken bone could make a very significant impact on the next few years of USC football and leave Corp holding a clipboard as a younger, just as talented quarterback lines up under center.

Quick Hits:
-Perhaps no unit in the country has been decimated by injuries like Tennessee's receivers, and the bad news continues with top returning receiver Gerald Jones suffering a high ankle sprain. Jones will be sidelined for three to six weeks, while Denarius Moore is out until mid-September and Austin Rogers will miss the season. The three players are the Volunteers' top three returning receivers.

-The next "scandal" at Alabama? Julio Jones and Mark Ingram go fishing.
