Colts RBs: The Colts could be in a major bind at running back with only two more recovery days before a visit to Tennessee on Thursday.
Mike Hart went out during the third quarter Sunday with an injury to his left ankle, the same ankle that caused him to miss the previous four games. Donald Brown finished the game on the sideline with an ankle injury.
Starter Joseph Addai has been out six weeks with nerve damage in his left shoulder and Caldwell could offer only, "Potentially, but not certain," of Addai's prospects of returning this week.
Other than Hart, Brown and Addai, there are only two backs on the roster, both undrafted rookies. Javarris James took all the snaps down the stretch Sunday. Joique Bell has played only on special teams since signing four weeks ago.
