NFL rushing leader Arian Foster didn't play over the final 10 minutes of the game.
Texans coach Gary Kubiak said Foster was hurting, so he was taken out. But there was some confusion as to what part of Foster hurt.
Although he had missed practice this past week because of an ankle sprain, Foster said "a muscle spasm in my glute" — fanny - was the problem Sunday.
Foster's 11-carry, 15-yard effort was the least productive of this breakout season. His previous low was 25 yards on 11 carries against the Giants.
