LOS ANGELES — Southern California quarterback Aaron Corp has a small crack in his bruised left knee and will be out about two weeks.

An MRI taken Wednesday revealed the crack on the head of Corp’s left fibula. The redshirt sophomore was rolled onto by a lineman during Monday’s practice.
Doctors found Corp has no ligament damage and won’t need surgery.
Corp was chosen by Carroll as the Trojans’ first-string quarterback coming out of spring practice.
Freshman Matt Barkley will take all the first-team reps during Corp’s absence. Veteran backup Mitch Mustain is also in the mix.
