The Houston Chronicle reports that Chris Brown could be back as the starting RB vs the Colts:

Chris Brown could start at running back for the Texans on Sunday. Steve Slaton is nursing a shoulder injury. Brown had 11 carries for 36 yards against the Titans last Monday night. “They haven’t said anything to me,” said Brown. “I prepare every week and practice hard and whatever happens, happens. I knew I was going to play a decent amount. I wasn’t sure how much. It depends on how the game was going to unfold, and we went from there. When they throw you in, you have to execute.”
