Denzel Ward suffered a knee injury in practice Thursday and is listed as questionable for the Texans wild card game on Saturday.  He was limited after suffering the injury.  It could come down to a game time decision.  Safety Grant Delpit was ruled out with his groin injury.  Cedric Tillman (concussion) and kicker Dustin Hopkins (hamstring) were also ruled out.  Amari Cooper returned to practice on Thursday and will face the Texans.
