Grimes (ankle) is listed as questionable for Sunday's game against the Lions.
Grimes hasn't played since Week 3, but he returned as a limited participant throughout practice this week. That puts him in contention to play Sunday, when starting tailback Lamar Miller (shoulder) is also considered questionable to suit up. While both players' statuses will need to be determined before a clear outlook on Houston's backfield can be shaped, Alfred Blue figures to see more touches than usual given the circumstances.
