"The info that I have is he's going to be fine," Kiffin said. "Training camp won't be an issue. ... But until our guys look at him, I don't want to say" the extent of Walker's injuries.

Kiffin said Walker was scheduled to fly to Oakland, Calif., on Wednesday evening in time to attend the final session of the Raiders' organized team activities today, though he won't suit up with quarterback JaMarcus Russell and his new teammates.

Oakland opens training camp July 25 in Napa.

"We are aware that Javon Walker was the victim of a robbery," Raiders spokesman Mike Taylor said in a statement. "We have been told that he will make a full recovery in the near future and resume his preparation for the 2008 NFL season."

Las Vegas police had planned to interview Walker at Sunrise on Wednesday as part of the ongoing investigation into his beating and robbery.

Detectives had been unable to talk to the 29-year-old since the Monday morning attack because of medical reasons, robbery Lt. Clint Nichols said.

Police had hoped their interview and a review of surveillance video from the Bellagio would shed light on what happened in the early-morning hours before the attack, Nichols said.

According to the celebrity Web site thedirty.com, Walker said three men with guns jumped him after he answered a knock on his door at the Bellagio, and then he was beaten, robbed and dumped in the street.

A statement by MGM Mirage, which owns the Bellagio, disputed that version of events.

"The facts that have been reported regarding the incident involving Javon Walker are incorrect," the statement said without providing details.

Hotel officials have turned over relevant surveillance video to Las Vegas police. The Bellagio has more than 2,000 security cameras.

A large amount of cash and expensive jewelry were taken from Walker, who was photographed earlier in the fateful evening spraying a nightclub crowd with champagne.

Walker signed a six-year, $55 million deal with the Raiders after the Denver Broncos released him in February. The former Green Bay Packers star has participated in offseason work with Russell, though Kiffin said two weeks ago that Walker was "a little heavy" for workouts.

Details of Walker's party night still were sketchy, and the Raiders weren't expected to make Walker available to the media on the final day of workouts, with today scheduled to be closed to reporters.
