HOUSTON (AP) -- Houston running back Arian Foster has injured his back against Indianapolis and his return is questionable.
Foster played on Houston's first series, but did not have a carry. He soon left the field and was taken to the locker room.
He missed practice this week with a hamstring injury, but started on Sunday night.
Houston led 14-0 in the first quarter.
