USC vs. Arizona injury update: Wildcats still reeling

The Arizona Wildcats still have a banged up roster, and help doesn't appear to be coming for either line.

Guard Trace Biskin and center Kyle Quinn are still questionable with toe and ankle injuries respectively. On defense, end Dominique Austin is out for the year with a foot injury, Ryan Finley reports.

Receiver Terrence Miller is also listed as out for Saturday's game against the USC Trojans in Tucson.

In addition, bandit safety Jared Tevis and defensive end Kirifi Taula are questionable.

The only positive movement on the injury report is receiver Johnny Jackson, who is listed as probable after missing last week with an ankle injury. Defensive tackle Willie Mobley is listed as probable with an ankle problem as well.

The Jackson improvement will bring a reliable pass-catcher to the slot position, although Garic Wharton held down the spot pretty well in the 52-17 victory against Washington. And on another relieving note, the mangled offensive line last week produced enough to give Ka'Deem Carey his best rushing performance of the year.
