Colts running back Joseph Addai says he's a ''long shot'' to play Sunday at Cincinnati because of a strained hamstring.
Addai was hurt on a carry late in the first quarter of last Sunday's game against Kansas City. He said Thursday he doesn't know when he will return to action.
Addai had the same problem three years ago and said he came back too early.
Addai has been one of the most productive Colts when healthy, but he has a history of injury problems. He has missed 14 games the past four years, including eight last season because of a shoulder injury.
Delone Carter and Donald Brown will get most of Addai's work. The Colts activated Darren Evans from the practice squad this week.
