Houston Texans running back Steve Slaton's status will be a game-time decision Sunday after he missed practice with an injured right shoulder.
Slaton has struggled with the shoulder injury for about three weeks and has been experiencing numbness in his right thumb.
"I think it's just going to take time," he said. "I've been playing through it, and I really don't think it's that serious. I think we just have to wait until Sunday to see how it feels."
Brown, who has seen increased action after Kubiak benched Slaton because of fumbling problems, has rushed for 234 yards and two touchdowns this season. Last week against the Indianapolis Colts, Brown carried 11 times for 56 yards and one touchdown.
Quin, who has started eight games this season, said he isn't sure if he had a concussion, and if he did, it was a mild one. Still, the Texans chose to sit Quin after he had headaches earlier this week.
Quin was disappointed to miss this game, in which a win would be key in keeping Houston's playoff hopes alive, but he was worried about the possibility of the injury becoming more serious by playing.
"I have a family at home, and it's not worth going out and risking re-injuring it even worse," he said. "You can sit out a week and hopefully get better and come back and be completely ready to go (rather) than trying to come back too early and risk taking another shot and doing some further damage."
Quin said he didn't lose consciousness when he was hit but that he was shaken up. He never experienced nausea from the blow.
