Early Wednesday morning (March 11), Slipknot guitarist Mick Thomson and his brother Andrew Thomson were rushed to the hospital following a knife fight, police confirmed to Billboard.

The brothers both sustained serious injuries, with Mick even having a stab wound in the back of his head, but police say none of the injuries were life-threatening. The incident took place at Mick's residence in Clive, Iowa. Both brothers appeared to be drunk when officers arrived, and they were transported to the hospital in separate ambulances.
