After leaving practice early for the third straight day Thursday, USC wide receiver Dwayne Jarrett (sprained shoulder) was listed as questionable for the third-ranked Trojans' game Saturday against Washington, ESPN's Joe Schad reported. Jarrett, who has been fitted with special shoulder pads, which could be helpful, will warm up Saturday and see how it feels before a decision is made.
Jarrett sat out USC's 28-22 victory over Washington State last weekend because of a sprained left shoulder.
With Jarrett's status uncertain, head coach Pete Carroll said Tuesday that that could mean additional playing time for freshmen Vidal Hazelton and Travon Patterson.
"They've got to grow up real fast," he said. "These guys are kind of in the mode already to get more playing time."
Injuries and inexperience have had an impact on USC through four games. The Trojans (4-0, 2-0), though, are unbeaten despite having eight starters or projected starters miss one or more games with injuries.
"I think it's a system thing," defensive end Lawrence Jackson said Tuesday. "You have this foundation in place. We have great depth around here. We have guys who are really good who haven't seen the field yet. The coaches do a great job of getting guys who are ready to play."
The narrow victory over Washington State and a 20-3 triumph at Arizona a week earlier, when USC led 3-0 at halftime, are quite different from the many blowout wins USC fans became accustomed to during the past four years.
"You come to expect the challenges and these are what they are this season," Carroll said. "Guys are getting banged up, but we have a lot of guys that can play, too. I'm not alarmed by it. If it continues, we just keep dealing with it and do the best we can."
The Trojans have won 49 of their last 51 games and a conference-record 28 straight at the Los Angeles Coliseum including their only home game this year -- a 28-10 victory over Nebraska on Sept. 16.
