More bad news for Vick Ballard.

The Indianapolis Colts running back tore his left Achilles tendon during Friday's training camp practice and could be lost for the season, ESPN reported. Ballard fell to the turf after catching a pass on a non-contact play and was headed for an MRI to confirm the diagnosis.

Ballard, who left the field on a golf cart after initially limping, was coming back after playing in only one game last season for the Colts because of a torn ACL in his right knee.

"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, according to ESPN. "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."

As a rookie in 2012, Ballard ran for a team-leading 814 yards and scored two touchdowns. In last year's season opener, he rushed for 63 yards on 13 carries before suffering the torn ACL.
