Rainey was released by the Steelers after a domestic dispute found him in trouble with the law. Police detained Rainey after he allegedly assaulted his girlfriend - a charge she would later deny. The Steelers released him after his rookie year that saw him emerge as one of the better return men in the game.
He was a lost cause as a running back, and it would seem Indianapolis would be looking to use him as a returner. David Reid has been less than stellar for the Colts in that capacity, and he could be on his way out.
Indianapolis (7-3) plays at Arizona this weekend.
