There are some high-profile injuries in the conference right now. Here's an update.
Arizona TE Rob Gronkowski (back): He's trying to practice this week in order to play at Iowa but the guess here is the best-case scenario is Gronkowski seeing only a handful of snaps. Coach Mike Stoops might opt to rest him hoping he'll be ready when the Pac-10 games start on Sept. 26. And, if Gronk plays, keep in mind he missed almost all of preseason camp. As good as he is, there should be some rust.
Arizona State DT Lawrence Guy (biceps): It appears Guy will play against Louisiana-Monroe. Dennis Erickson told the Arizona Republic on Tuesday: "I don't think he's 100 percent, but he's pretty close."
Oregon FS T.J. Ward (ankle) & LB Spencer Paysinger (elbow): While Oregon coach Chip Kelly calls all his injured players "day-to-day" -- thereby forcing all haggard sportswriters to reply, "Aren't we all, coach?" -- Ward seems far closer to doubtful than questionable for the Utah visit. Paysinger practiced Tuesday, so he sounds probable.
Oregon State WR Darrell Catchings (wrist): Catchings was catching Tuesday, so let's upgrade his status to questionable. If he's ready to go that should elevate the Beavers passing game with a tough Cincinnati squad coming to Corvallis. Some other injury info here.
Stanford DT Matt Masifilo: Masifilo suffered a knee injury at Wake Forest and will be out six weeks. The good news is backup Sione Fua has experience.
UCLA RB Christian Ramirez (ankle), DE Reginald Stokes (knee), OL Nick Ekbatani (knee) & WR Gavin Ketchum (hamstring): Though it's unlikely any of these four will be available for Saturday's game with Kansas State, all four are at least doing light running, meaning they could be ready after the bye week for the Pac-10 opener vs. Stanford on Oct. 3.
USC QB Matt Barkley (shoulder) & FS Taylor Mays (knee): Barkley didn't throw during Tuesday's practice, so it's becoming increasingly possible that sophomore Aaron Corp will start at Washington. That might make things interesting if Corp is lights out. Mays is a senior and a two-time All-American who came off the bench in his first game as a true freshman and has started every game since. He's from Seattle. Odds are that Mays will play, even if he sits out all week.
Washington DT De'Shon Matthews (knee) & DE Darrion Jones (knee): Both are decidedly questionable and closer to doubtful. The reason that this is big is because USC has a dominating offensive line -- one that is surely unhappy with how it performed at Ohio State. The Huskies aren't deep on the D-line in any event.
Washington State LB Andy Mattingly (concussion, thigh): The Cougars are banged up -- it was too complicated to list here. With another run-and-shoot offense -- SMU -- coming to town, the defense can't afford to be missing many starters, such as Mattingly, who is questionable.
