Colts starting running back Vick Ballard will miss the rest of the season with a torn anterior cruciate ligament in his right knee suffered without even being hit. Coach Chuck Pagano said Friday that Ballard was hurt making a cut in practice Thursday.
Former Giants star Ahmad Bradshaw is expected to start Sunday against Miami, and the Colts are promoting rookie Kerwynn Williams, their seventh-round draft pick, from the practice squad.
Ballard was Indy’s top rusher in 2012 with 814 yards and two TDs. Last week, Ballard ran 13 times for 63 yards. Full story for BostonGlobe.com subscribers.
