"Long story short? [Rob Brewer] sucks. He hit me and then we fired him." So said Unwritten Law's Scott Russo to MTV News April 11, announcing that guitarist Brewer had been kicked out of the band after an onstage fight March 23 at the House of Blues in Anaheim that left Russo minus a tooth and Brewer missing part of his pinky.

Russo says the onstage argument was over Brewer's refusal to play "F.I.G.H.T," from the band's new album Here's to the Mourning. "So I said on the microphone that Rob's mad at us. I went over to try and give him a hug, and he pushed me." Russo says he threw some water at Brewer, whereupon "he knocked one of my teeth out. So I walked offstage. Rob did too. But I walked back out, threw his guitar on, and we finished the set without him. Then I threw his guitar into the crowd and gave it to the kids."

Russo says he found Brewer backstage holding a vodka bottle. "He tries to hit me over the head with it.... The bottle connects with the top of the door jamb and smashes, cutting half of his right pinkie off. Needless to say, he couldn't play the next two or three shows because he had to have surgery to reattach his torn ligaments."

According to Russo, Brewer also shoved a fan who made his way backstage to meet the band in Anaheim. "He yelled at the kid, 'What the fuck are you doing in my [dressing] room?' and he hit the fan across the room. We were just, like, 'What the fuck is wrong with him?' "

For now, the band plans to continue touring with Sum 41 as a quartet. Original band drummer Wade Youman was fired from the band a little over a year ago.
