Colts running back Joseph Addai left Sunday's game against the Kansas City Chiefs with a right hamstring injury, and the team announced that his return is questionable.
Addai was hurt on a carry late in the first quarter. He has six carries for 19 yards and one catch for 6 yards.
Addai has a history of injury problems. The only season he made it through without missing a game was his rookie season in 2006. He missed eight games last season with a shoulder injury.
Delone Carter replaced Addai in the lineup.
