Defensive end Kalimba Edwards is questionable for Sunday's game against Kansas City with a hip injury.
Edwards was injured at the end of Thursday's practice.
If Edwards can't play, at least Derrick Burgess is healthy.
But the injury would alter any plans of a rotation to keep Burgess fresh.
It would also mean Jay Richardson would stay in the starting lineup with Trevor Scott filling in on passing downs for Richardson.
Another option would be give rookie Greyson Gunheim some reps.
Linebacker Ricky Brown (groin) and center Jake Grove (calf) are out for this Sunday.
Look for Jon Alston to replace Brown in the starting lineup and John Wade to start his third straight game at center.
Brown will miss his fifth straight game.
Brown dressed for practice today, but will begin working toward getting on the field again Sunday before the game, when a lot of injured players work out.
Wide receiver Chaz Schilens (Achilles' tendonitis/ankle) and tight Zach Miller (groin) are questionable.
Schilens trying to play with the injury has only made his ankle worse. Miller was hurt in the Raiders' win at Denver.
*Congratulations to Lane Kiffin, who appears to have landed the head-coaching job at the University of Tennessee.
His gamble of taking the Raiders job paid off.
Kiffin interviewed for the job at the University of Minnesota before being hired by the Raiders, so college is a place Kiffin definitely saw himself working.
And after not getting the Arkansas job last year, he actually got a better job in the Southeastern Conference.
No matter what happened with the Raiders, Kiffin was bound to be OK.
If he'd won more than five of the 20 games he coached with the Raiders, he would have been a hot commodity around the NFL for winning games with the Raiders.
And if things flamed out (as they did) no one would hold it against him, as he was a young coach put in a tough spot.
My guess is he won't be as critical of players publicly as he was with the Raiders with boosters all over his every word.
Good luck, Lane. You better hope things work out better for you than the last Raider coach that was fired and ended up with a college job, Bill Callahan.
