Indianapolis Colts running back Donald Brown underwent knee surgery Tuesday and will be out two to three weeks, Colts interim head coach Bruce Arians said, reports the Indianapolis Star.
Backup Vick Ballard will start on Sunday when the Colts play the New York Jets.
Delone Carter is expected to back up Ballard, who has 42 yards on 21 carries in limited action through four games.
Brown tore cartilage in his knee on the Colts' final two-point conversion in the team's 30-27 victory over the Green Bay Packers, and had surgery on Tuesday to repair the damage. Arians said Brown didn't injure the knee on his celebration after running for the conversion. Brown has 239 yards rushing and one touchdown this season.
