Arian Foster hamstring tightened up

After working as the feature back in the 1st half of Sunday's game against the Dolphins, Texans RB Arian Foster didn't step on the field in the 2nd.  HC Gary Kubiak said aftewards that Foster was simply fatigued.  But Foster admitted that his hamstring tightened up at halftime.  "I pulled myself out because I felt it was getting a little tight," he said.  This was our worry with Foster.  He had a good week of practice, but live game-action is a completely different animal.  His status for Week 3 is now up in the air.  Hang on tight to RB Ben Tate if you own him.
