And with such a short turnaround before the Thanksgiving Day game at the Dallas Cowboys, their availability is in serious doubt.
Rivera was hit on a helmet-to-helmet blow by Titans free safety Michael Griffin downfield on a ball Rivera nearly held onto for about a 30-yard gain. Instead, Griffin was flagged for a 15-yard personal foul and might just have a FedEx folder with a fine in it at his locker this week.
Jenkins, meanwhile, was injured tackling Titans running back Chris Johnson early in the fourth quarter after a six-yard pickup. Jenkins was replaced on the field by Chimdi Chekwa.
Linebacker Kevin Burnett also could not finish the game. He suffered a contusion to a quad in the fourth quarter and was replaced by Miles Burris, who was making his season debut after offseason knee surgery. Burnett had a game-high 11 tackles, with half of a sack.
Also, running back Rashad Jennings, who rushed for 73 yards on 16 carries, left the game with a stinger but returned, as did receiver Rod Streater, who took a blow to his hip.
The Raiders may receive some offensive help this week as Raiders radio broadcaster Greg Papa said “all indications” are that running back Darren McFadden, who has missed the last three games with a strained right hamstring, will play against the Cowboys.
