Raiders coach Lane Kiffin finally spoke to Walker by phone yesterday morning, more than 2 days after Walker was discovered unconscious and beaten on a back street near the Las Vegas Strip following a night of partying. Walker was released from a hospital after treatment for a concussion and facial injuries.

"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 last night in time to attend today's final session of Raiders' organized team activities, although he obviously won't suit up with quarterback JaMarcus Russell and his new teammates. Oakland opens training camp July 25 in Napa.

A Las Vegas police spokesman said a large amount of cash and expensive jewelry were taken from Walker, who was photographed earlier in the evening spraying a nightclub crowd with champagne. His agent, Kennard McGuire, said Walker was "recovering in a private environment."
