"I wish we had more time," Kiffin said. "The reality is I don't think we're very good right now as a team. Whatever that first game was, I think we're going to have a big test going into Tennessee against that team. If we don't have our stuff right and our guys aren't right we'll get run out of that stadium real quick."
The Raiders beat San Francisco 18-6 in their preseason opener last week and will play the Titans on Friday night in Tennessee.
Unless the team makes marked improvement from its practice Tuesday, Kiffin worries Oakland could get blown out.
The Raiders went through one of their most sluggish workouts of camp in front of a few hundred onlookers from one of the team's booster clubs. Quarterback JaMarcus Russell had another rough day, throwing a pair of interceptions. Backup Andrew Walter also threw a pair of picks while Marques Tuiasosopo had one of his own.
Throw in a few penalties for false starts and a couple of dropped passes and it's easy to see why Kiffin is concerned.
"I didn't think we were very crisp, especially early," Kiffin said. "A number of penalties early. We restarted the whole 9 on 7 down there due to that. I didn't think we were very crisp in the passing game until we got to 7 on 7. Lot of incompletions, lot of poor timing so that's continuing to be disappointing."
Russell did rebound, throwing a pair of sharp touchdowns to tight end Zach Miller and another to Javon Walker.
Other news and notes from camp:
· Cornerback Nnamdi Asomugha left practice and was taken for an X-ray after complaining of soreness in his foot. No word on the results or how long Asomugha might be out.
· Rookie safety Tyvon Branch had successful surgery to repair his broken right thumb and will rejoin the team in time for the flight to Tennessee.
· Oakland cut linebacker Malik Jackson and signed defensive back Nick Sanchez, who was listed as a safety in college at Stanford. Sanchez got off to a good start, intercepting a pass for Walter.
· Linebacker Ricky Brown was back working with the starting defense after sitting out some time due to a sore back. Brown took the majority of reps with the starters while Robert Thomas went back to working with the backups.
· Wide receiver Johnnie Lee Higgins had his worst day of camp, allowing three passes to slip through his hands. Two of the passes wound up being intercepted, one by safety Michael Huff and the other by cornerback DeAngelo Hall.
· Wide receiver Ronald Curry also had a rough afternoon, dropping an easy pass across the middle from Russell during team drills.
· Aaron Elling, who is filling in while kicker Sebastian Janikowski recovers from a hamstring injury, made good on a pair of field goal attempts from 40 yards.
· Walker had what Kiffin called his second-best practice of training camp. The veteran wide receiver ran well, got off the line with no problem and hauled in a trio of passes during team drills.
· The Raiders practiced a "last-play" drill in which the defense was challenged to prevent the offense from scoring on the final play. Oakland employed a 1-2-8 alignment featuring Derrick Burgess as the only defensive lineman on the field with linebackers Kirk Morrison and Thomas Howard.
· Mario Henderson, the second-year offensive tackle, continues to have his problems. During one team drill the offense ran a rollout play to the left but Henderson went the wrong way and drew the wrath of Kiffin.
