Vick Ballard tore his Achilles on Friday.

Ballard missed all but one game last season for the Indianapolis Colts with a torn ACL.

"When you see someone like Vick Ballard go down who's worked so hard to get back, it's tough, but it happens," Colts owner Jim Irsay said. "As soon as you get to camp, those things happen. He's still young and he's got a full career ahead of him so we have to do an MRI and see exactly what it is and then go from there. But you really hope to not hear any of that kind of news."
