''It completely changes what we've been doing,'' Turner said. ''Charles has been playing in so many spots. He's one of our captains, one of our leaders. Now we have to sort out how we fit, not only our starting four ... but then how we fit all our nickel packages. That's something we're going to spend a lot of time with over these next two days.''
Woodson and Gibson were both injured in the first half of Sunday's 38-17 win over Buffalo. Neither player looked seriously hurt, but after each was taken to the locker room tests revealed the extent of each injury.
Gibson, according to one team source, is all but certain to be finished for the year and is likely to be placed on injured reserve in the coming days.
Woodson, Oakland's franchise player, has a slim chance of playing again this season but not much. His injured leg does not require surgery but there are other issues facing the four-time Pro Bowler.
Considering his contract status -- Woodson could become a free agent at the end of the year -- it's even conceivable to think that Woodson might have played his final game as a member of the Raiders should the team not be able to reach a long-term deal with their talented cornerback.
Regardless, Oakland will be scrambling this week to field a healthy secondary. Ronaldo Hill suffered a cracked bone in his hand against the Bills, extending the Raiders' injury woes.
With Woodson, Gibson and Hill out for most of the game against Buffalo, Oakland had to rely on rookies Fabian Washington, Stanford Routt, and Chris Carr along with veteran safety Jarrod Cooper. All three are likely to be back in the lineup against the Titans, particularly Washington who has played well over the last month as his playing time has increased.
''All year this year we've played a lot of young guys,'' Turner said. ''You look out there and there are a number of times when you put Tommy Kelly and Stuart Schweigert, then you have the three young guys in there, there's five or six guys that are first- and second-year guys. I expect fewer (mistakes) because each week they should be getting better and understanding. Fabian's been playing 40 snaps a game. He'll get 60 this week.''
* Wide receiver Randy Moss, who played in spot situations and caught three passes for 43 yards and a touchdown against the Bills, did not suffer any setback by playing. ''Randy was no worse than he was (before the game),'' Turner said. ''I think each day he'll continue getting better.''
* Center Jake Grove is expected to return to practice this week and could be back in the starting lineup for Tennessee.
