NAPA, Calif. (AP) -No. 1 overall draft pick JaMarcus Russell and the Oakland Raiders failed to agree on a contract before the start of training camp Friday, forcing the quarterback to miss the team's first practice.
"We feel that we've made some strides," Kiffin said. "We felt that Zach was going to be at this practice, even up until a few minutes before practice. But at the last minute, it just didn't happen."
"It just flared up on me while I was working out," Burgess said. "We decided, the doctors decided, it's better to get it done, get it out of the way so it won't be a problem in the future."
Bush, a fourth-round pick, missed almost all of last season at Louisville with a broken leg and Kiffin doesn't want to rush the rookie back.
Talks between the Raiders, Russell and his agent, Eric Metz, have been ongoing for weeks but the sides have yet to strike an agreement. Metz has not commented publicly on the talks and didn't return calls seeking comment Friday.
The deal is so complex that the Raiders have had as many as six people in their front office working on the contract.
While Russell's teammates want him in camp as soon as possible, they understand his situation.
"It's important, but he's got to take care of his own business, too," receiver Jerry Porter said. "I'm not going to comment on his money. His agent and our GM will take care of their business."
The Raiders used the No. 1 overall pick on Russell in April, making him the cornerstone of a rebuilding project for a team that had won just 15 games the previous four seasons.
"It's huge," he said. "Because these first few weeks, the practices that you get and the work you get you never get back. I have not been the top pick, but being in that situation where there are a couple of sides to the thing ... it takes time. Hopefully it will get worked out to where everybody's happy and we can get him in here and get him working."
Russell impressed his new coaches during offseason workouts but still has plenty to learn as he tries to adjust to the speed and complexity of the pro game.
Russell went 25-4 as LSU's starting quarterback, capping his career by throwing for 332 yards and two TDs in a 41-14 Sugar Bowl win over Notre Dame. He finished his career with the Tigers by throwing the second most touchdown passes (52) and having the second-highest completion percentage (61.9 percent) in school history.
