USC injury updates

• Rey Maualuga -- Official word is that he has a knee sprain. What does that mean? Good question. About.com says that's "not a terribly useful diagnosis" because it tells you nothing about which ligament is hurt and how badly it's hurt. Worst case? UCLA fullback Trevor Theriot suffered a "knee sprain" in practice this week and his season is over. Maualuga will be evaluated further and we'll know more in a few days.
• Brian Cushing -- USC's other All-American linebacker broke a bone in his hand. This guy can't catch a break, so to speak.
• Zack Heberer -- Another reason for Trojans to hate Corvallis ... turf toe.
• Taylor Mays -- Suffered from a bruised chest, causing him to cough up blood during the game.
• Mark Sanchez -- You saw him limping. I saw him limping. But he kept playing after that scramble and didn't show any ill effects. A USC spokesman says he's fine.
