Nick Polk spent last season on the IR and he has been placed on IR again. He was recently released from the roster in order to make room for RB Ronnie Brown, but after he cleared waivers, he was placed on IR by the Bolts.
What injury does he have? I am going to guess headache or something like that. Just a way to keep another body on the roster.
