Uh-oh, Houston fans. Arian Foster injured his groin at Houston practice last night, and it looks like it's going to require surgery. That will mean going on IR-designated for return, taking Foster out of action for at least eight weeks of the regular season. So who do you want to count on alongside your questionable quarterbacks, Texans: Chris Polk, who can't stay healthy, or Alfred Blue and his league-worst rushing DVOA from last season? Or is there going to be a Chris Johnson or Knowshon Moreno signing here?
