The Colts starting back Joseph Addai left Sunday’s game against Kansas City with an apparent shoulder injury.
The team would not tell which shoulder was hurt.
Addai suffered the injury on a rush attempt late in the third quarter. Chiefs defensive end Glenn Dorsey hit Addai, thus driving Addai’s head and shoulder into the turf.
Mike Hart replaced Addai and scored the game-clinching touchdown late in the 4th quarter.
