Foster returned to practice this week after missing the season opener because of a left hamstring injury. Kubiak says Foster "looks ready to play."
Foster, who ran for 1,616 yards last season to lead the league, has been bothered with the injury for a month.
While Foster should return Sunday, the Texans will be without running back Derrick Ward who is out with a sprained right ankle. Receiver Kevin Walter remained out of practice Friday with an injured left shoulder and Kubiak says he will be a game time decision.
