Crosby, who had been listed as doubtful, has been sick all week and didn't practice once, marking the first time this season the two-time Pro Bowler missed a practice. However, a source told ESPN that Crosby has "a real chance to play and wants to."
Crosby has been dealing with the knee injury since Week 2. He began pushing to play Saturday, even though the Raiders have a bye next week and some think it would be smart to take the two weeks to rest and recover.
Crosby, who has 10.5 sacks, has not missed a defensive snap since the Raiders' blowout loss at the Chicago Bears on Oct. 22. He has played every snap in seven of Las Vegas' 11 games this season.
