Indianapolis Colts rookie Vick Ballard will get his first NFL start Sunday against the Jets.
Starter Donald Brown is out at least two weeks after having knee surgery, interim head coach Bruce Arians announced Wednesday at his press conference.
Brown suffered torn cartilage in his knee on a two-point conversion with 35 seconds left in Sunday's victory over the Green Bay Packers.
Ballard has been used primarily on third down and as a short-yardage back. He averages 2.0 yards per carry (21 carries, 42 yards) and is a physical, hard-nosed ballcarrier with average speed compared to Brown.
Brown got off to a slow start this season but bumped his average to 4.0 yards per carry with 239 yards on 60 carries before he was hurt Sunday.
Arians said Brown's surgery, like the injury, was nothing serious and projected Brown could miss 2-3 weeks.
