“Sure. He hasn’t had a chance to get out there,” Carroll said. Sarkisian said he understands Booty’s dilemma. “Any time you don’t play to your standards, you want an opportunity to redeem yourself and now that he’s injured, he’s losing that opportunity,” Sarkisian said. Booty said he believes he might be able to play. “I’m doing everything I can,” Booty said. “Some of the swelling’s gone down in my finger. It’s not quite as bad as it was.” Sanchez said he is ready, although he threw an interception and fumbled a snap in practice. “I feel pretty comfortable,” he said. “It’s just a different feeling. I don’t like it or not like it. But every kid dreams of being a starting quarterback.” Tailback Stafon Johnson, the lone breakaway threat at the moment, said he feels his bruised foot might improve enough to enable him to play against Arizona. “It’s feeling like I might make it,” Johnson said. “It’s about 75 to 85 percent, but I want to be 90 percent if I play.” Center Matt Spanos, who required stitches in his hand, will start. Linebacker Thomas Williams limped noticeably Tuesday and did not practice. Clay Matthews will start if Williams is unable to play. Tailback Joe McKnight left practice because he felt sick but said afterward he was OK. The savior? Bush update A sports marketer who allegedly made improper payments to Reggie Bush while the Heisman Trophy winner was still at USC agreed to meet with NCAA investigators and provide documentation of financial transactions between the two, according to a report. Lloyd Lake, who hoped to start a budding business by representing Bush, is expected to file a civil lawsuit in San Diego against Bush later this month, seeking to recoup money allegedly given to Bush and his family. Extra work needed David Buehler, who had an extra point blocked by Stanford, had two kicks blocked in practice Tuesday.

By Scott Wolf STAFF WRITER USC will start sophomore Mark Sanchez at quarterback against Arizona on Saturday, barring a sudden improvement to starter John David Booty’s broken finger. “I would think (Sanchez starts),” offensive coordinator Steve Sarkisian said. “If (Booty) is going to play Saturday, he’d have to do something (today) and really practice a lot on Thursday.” AD Quality Auto 360p 720p 1080p Top articles1/5READ MOREChargers go winless in AFC West with season-ending loss in Kansas CityBooty threw about 50 passes before practice Tuesday and said he made progress from the previous day. He was able to grip a football, but he said the release bothered him. “It felt better than I expected but my accuracy is not what I wanted right now,” Booty said. USC coach Pete Carroll said he is preparing for Sanchez to start but would not make an official decision until later in the week. However, Carroll added it might be better for Booty to take a week off to let his finger recover. “I’m thinking long-term,” Carroll said. “John might be able to play Saturday, but what happens next week and the next week.” Carroll said he would feel some apprehension if Sanchez started.
