INDIANAPOLIS (AP) -- The Indianapolis Colts have placed former Michigan running back Mike Hart on injured reserve, ending his season.
To reinforce the depleted backfield, the Colts promoted Chad Simpson from the practice squad and re-signed Clifton Dawson, who was cut in August. They waived defensive back Nick Graham to make room for Dawson on the roster.
Hart, a sixth-round pick, hurt his right knee on Sunday against Baltimore. The rookie was placed on IR on Wednesday.
