Brown, who did not play in Houston's first preseason game Saturday night, appears to have been the victim of the game circumstances. Head coach Bill O'Brien said he stuck with starter Jonathan Grimes because Houston's inept offense didn't get off many plays in the first half, the Texans' official site reports. O'Brien added that he wanted to get rookie Alfred Blue some work, too, and it just worked out that Brown didn't get into the game. We expect to get more clarification in the coming days regarding the running back depth chart. An unofficial depth chart for Saturday's game was released by the team earlier in the week and it showed Brown as the number two behind starter Arian Foster, who was unavailable Saturday due to injury.
