Three of the Pac-10's most exciting offensive players are expected to suit up for their teams on Saturday.
USC wide receiver Dwayne Jarrett, who had only one catch for five yards last week against Washington and has been rehabilitating a sprained left shoulder, will play against Arizona State, coach Pete Carroll said.
Jarrett's fellow wide receiver, Steve Smith, who suffered a high ankle sprain last week and missed Monday's practice, will also return Saturday. Smith returned to practice on a limited basis on Wednesday and will practice Thursday.
USC is ranked No. 3 but has beaten Washington State and Washington by only six points apiece in each of the last two weeks.
"We're playing pretty solid football," Carroll said Tuesday. "The margin of victory is just closer. Each play becomes crucial."
In other Pac-10 injury news, California running back Marshawn Lynch will play through an ankle sprain at Washington State on Saturday, coach Jeff Tedford said.
Lynch has been hampered by a troublesome ankle all season, but had still managed to top 100 yards in four consecutive games.
"He reirritated it during the game," Tedford said Tuesday. "But he's moving around fine. He's just a little bit sore. I wouldn't say he's questionable. I would say he'll play for sure."
