Colts running back Ahmad Bradshaw will have season-ending neck surgery, according to ProFootballTalk.
Bradshaw had missed the previous two weeks with a neck injury after rushing for 186 yards and two touchdowns in Indianapolis' first three games of the season. The Colts lost starting running back Vick Ballard to a torn ACL earlier in the season. Indianapolis currently has running backs Trent Richardson - acquired from Cleveland in a trade on Sept. 18 - and Donald Brown available on their active roster.
Bradshaw is in his first season with the Colts after spending six years with the New York Giants, who drafted him in the seventh round out of Marshall in 2007.
