The Colts are thin at running back with loss of Daniel Herron

INDIANAPOLIS -- The Indianapolis Colts have suddenly become thin at running back behind starter Frank Gore.

The Colts waived-injured running back Daniel Herron on Sunday. He'll go on injured reserve if he clears waivers.

Herron injured his shoulder while returning a kickoff in the second quarter of last week’s preseason finale against the Cincinnati Bengals.

Herron walked out the locker room after the game wearing a sling and clearly frustrated over the injury.

“It’s unfortunate what happened to Boom on the return,” Colts coach Chuck Pagano said the day after the game. “That can happen at practice. It can happen at any time. It’s a decision that I made. I’m not going to look back on it, anything like that. Again, it is what it is.”

The loss of Herron goes with the hamstring injury to Vick Ballard and rookie Josh Robinson recently dealing with a concussion.

Undrafted rookie free agent Tyler Varga is the only other healthy running back besides Gore currently on the roster.
