CINCINNATI (AP) -- The Indianapolis Colts' struggling offense are missing running back Joseph Addai and left tackle Anthony Castonzo for their game Sunday against the Cincinnati Bengals.
Addai didn't practice all week because of a hamstring injury. He had been listed as questionable on Friday.
Castonzo also is inactive Sunday with a sprained ankle. Jeff Linkenbach takes his place, moving from right to left tackle. Guard Ryan Diem, limited by an ankle injury, moves to right tackle.
The Bengals are missing middle linebacker Rey Maualuga, who sprained an ankle on Thursday. Rookie guard Clint Boling also is inactive.
