Mick Thomson, the lead guitarist of Iowa-based metal band Slipknot, was stabbed in the head during a drunken knife fight with his brother in Clive, Iowa early Wednesday morning. Mickeal Gordon Thomson, 41, and Andrew John Thomson, 35, were armed with knives and fighting in the front yard of their home in the 1900 block of Northwest 129th Street at about 4:25AM.

Chief of Police Michael G. Venema said that his officers responded to calls from neighbors about the men fighting in front of their home. Both men were drunk and had sustained severe but not life-threatening injuries. They were both taken to hospitals in separate ambulances.

Slipknot’s manager confirmed that Thomson was involved in the incident and maintained that the guitarist’s injuries won’t stop him from touring with Slipknot on their upcoming tour. The group’s lead singer, Corey Taylor, also tweeted an update on Thomson’s condition and thanked their fans for support:

Mick Update: from what I've heard he's okay. We're sendig him all your thoughts. Thank you for that.
