Though we should probably expect Addai in uniform today, the bulk of the carries will be given to Delone Carter and Donald Brown. Addai will only play if there is an injury. Joseph is nursing a hamstring injury that has plagued him all year. He's also an injury prone player, and has been his whole career.
The positive news on the injury front is it looks like Anthony Castonzo and Drake Nevis are back today for the Colts. Castonzo is the team's best offensive lineman at left tackle, and Nevis is the team's best defensive tackle. Both are rookies, and both have been out since the Week Four loss to the Tampa Bay Buccaneers.
Ryan Diem might return as well, thus solidifying the Colts offensive line and giving them, at least, a chance to win their first ballgame of the year.
