Williams’ File Is Sent to NCAA

USC sent Mike Williams’ summer school grades and other information to the NCAA on Tuesday with hopes that a decision on the All-American receiver’s eligibility is made within a few days.

“It is sitting at the NCAA office and we are awaiting a final ruling,” said Todd Dickey, USC’s vice president and general counsel.

USC, which begins its season Saturday against Virginia Tech, has applied to the NCAA for a progress-toward-degree waiver and reinstatement of Williams’ eligibility. Williams left school in February, announced he was turning pro and hired an agent.

Williams has not practiced with the team since Aug. 10.

Suspended running back Hershel Dennis will not play against Virginia Tech, Coach Pete Carroll said.

According to law enforcement sources, Dennis is the focus of a sexual assault investigation that may involve a member or members of the team. It is not clear what Dennis’ role was in the alleged Aug. 16 incident. Dennis’ attorney, Carmen Trutanich, confirmed that he had been contacted by police, but refused to comment further.

Injuries remain a concern for UCLA, with tight ends J.J. Hair, Matt Raney and Keith Carter missing practice.

“Our issue right now is when will these guys be back,” said assistant coach Jon Embree, who had only starter Marcedes Lewis and walk-on Will Peddie available.

But several injured Bruins have a chance to play in the Sept. 4 opener against Oklahoma State at the Rose Bowl.

Coach Karl Dorrell said ends Kyle Morgan and Brigham Harwell, each of whom are recovering from arthroscopic knee surgeries, could return to practice as early as Monday.

Linebacker Tim Warfield, who suffered a minor knee injury that did not require surgery last week, appears close to returning.

Middle linebacker Justin London, sidelined because of a high ankle sprain, said he plans to play against the Cowboys.
