Also, Joseph Addai has an injured hamstring, and his return is questionable.
Addai's backups on the depth chart are Delone Carter, the rookie out of Syracuse and Donald Brown, the third-year player out of Connecticut. Addai has had injury woes in the past, but so far this season Colts head coach has not hesitated to give some of the load to Carter. Carter as also shared some of the kick and punt return duties for the Colts this season.
The Colts currently have a 17-0 lead over the Chiefs early through the second quarter in Lucas Oil Stadium as Matt Cassel has struggled to find a rhythm thus far.
