The Texans will need some sort of effort from the running game Sunday to beat the Steelers in Pittsburgh, and they got some good news in that regard Monday as RB Ahman Green took part in practice and went full speed despite previous issues with his groin.  Even with Green being ready, look for the Texans to use a couple of backs to try and get past the Steelers, including Green, rookie Steve Slaton, and Chris Taylor.  Chris Brown is done for the year after being placed on IR over the weekend.
