The Colts and Chiefs are doing battle in this week’s biggest game for positioning in the Andrew Luck derby and the Colts are now without their top running back.

Joseph Addai went down hard on a running play in the first quarter and limped off the field with an angry expression on his face. He’s on the sidelines with his hamstring heavily wrapped and his return is being called questionable. Addai had four touches on the first Colts possession, which wound up with a Pierre Garcon touchdown reception.

The Colts lead 10-0 after a Adam Vinatieri field goal. Delone Carter and Donald Brown will handle the rushing duties in Addai’s absence.
