Some injury notes based on news reports.

Arizona
Guard Conan Amituanai sprained his knee against Washington. He won't play against Stanford. Defensive tackle Earl Mitchell was hurt in a freak accident on Oct. 9 -- he was knocked out by a door and required stitches -- and didn't play Saturday, but he might return this week. Receiver Bug Wright (knee), defensive end Brooks Reed (ankle), running back Nic Grigsby (shoulder), running back Keola Antolin and defensive end D'Aundre Reed (hand) are all questionable.

Arizona State
The Sun Devils got two player back at Washington State -- guard Garth Gerhart and safety Ryan McFoy -- and didn't suffer any additional injuries. Receiver Kerry Taylor (hamstring), guard Matt Hustad and cornerback Omar Bolden (knee) each missed the Washington State game and are questionable this week.

California
After taking the weekend off, the Bears may get guard Matt Summers-Gavin (shoulder), wide receiver Nyan Boateng (foot) and tight end Spencer Ladner back for the UCLA game. On the downside, receiver Verran Tucker is battling a calf injury and backup nose tackle Kendrick Payne, who didn't play against USC, is doubtful with plantar fasciitis.

Oregon
The Ducks only practice Wednesday and Friday during their bye week. It's unclear if quarterback Jeremiah Masoli (knee) or safety T.J. Ward (ankle) will be ready to participate. Offensive tackle C.E. Kaiser sat out all last week with a shin injury but he played against UCLA.

Oregon State
Offensive guard Gregg Peat bruised his knee against Stanford but he should be able to play after the bye week at USC. Running back Ryan McCants (knee) has yet to play this season but he is questionable for the USC game. Receiver Darrell Catchings (ankle) isn't expected to be ready by Oct. 24.

Stanford
Defensive end Erik Lorig didn't play at Oregon State because of a groin injury. Safety Delano Howell is nursing a quad injury. Both are questionable for the visit to Arizona.

UCLA
Linebacker Reggie Carter played through a sprained knee against Oregon but he's questionable for the Cal game. Tailback Johnathan Franklin and safety Glenn Love are both nursing sprained ankles. Defensive end Korey Bosworth bruised his ribs but is probable for Saturday.

USC
Receiver Ronald Johnson (collarbone) and defensive end Armond Armstead (foot) are expected to be cleared to play at Notre Dame.

Washington
Offensive guard Greg Christine broke his fibula against Arizona and is likely done for the year. He was replaced by sophomore Nick Wood. Running back Chris Polk played through a sprained shoulder against Arizona. Linebacker E.J. Savannah and defensive tackle Cameron Elisara are nursing stingers.

Washington State
It's good news and bad news for the Cougars. Cornerback Daniel Simmons may be done for the season after breaking his leg against Arizona State. On the plus side, guard Zack Williams (ankle) should be ready for the visit to California after the bye week. Tackle Steven Ayers (ankle) and guard B.J. Guerra (knee) are questionable, as are defensive tackle Bernard Wolfgramm (hip) and linebacker Alex Hoffman-Ellis (staph infection).
