Arian Foster unsure of Week 1 status

Texans RB Arian Foster (hamstring) admits that he's not sure if he'll be able to play against the Colts on Sunday.  "I don't know," Foster said.  He did say that he ran "as close to full speed as you can get without going full speed" on Wednesday.  Still, we hate to hear a player questioning his health like this.  When Foster does return, we'll be watching to see if he's running tentatively.
