Colts beat writer Mike Chappell reports that RB Delone Carter is recovering from offseason thumb surgery. We're not sure when Carter suffered the injury. He left the Week 15 game what the team called a "forearm" injury but returned the following week. We do know that Carter is tentatively expected to be ready for the starting of training camp, where he'll look to push RB Donald Brown for carries. We'll pass along more information when we get it.
