In disturbing news from outside the world of classic rock, Slipknot guitarist Mick Thomson was reportedly stabbed in the back of the head during a drunken knife fight with his brother early in the morning of March 11.

According to the Des Moines Register, Thomson (41) and his brother Andrew (35) were found fighting with knives on the front yard of a home on Northwest 129th street at 4:25AM. Officers reported the brothers were both drunk and had sustained serious but non-life threatening stab wounds. The fight reportedly began inside the house, but moved outside when things got physical.

In what was probably a very wise move, the two men were taken in separate ambulances to the hospital. Slipknot, who released the .5: The Gray Chapter album last fall, kick off their next scheduled series of tour dates April 25 in Fort Myers, Fla. Thomson joined Slipknot in 1996 and has performed on all five of their albums.

3/22 Update: According to the Des Moines Register, both Mick and Andrew Thomson have been charged with disorderly conduct as a result of this incident. They each face up to 30 days in jail, a fine ranging between $65 and $625 dollars, or both.
