Machine Head have already been forced to sit out the December 4 show with Dethklok, All that Remains and The Black Dahlia Murder due to Disney’s corporate policy. Now it looks like that’s not the only show on the tour they won’t be playing. While Roadrunner had no comment when we reached out to them, Blabbermouth cites Robb Flynn’s health, with an excruciatingly detailed quote stating that he’ll be undergoing emergency surgery due to a hernia. The surgery is slated to take place tomorrow (14), with the band rejoining the tour on November 24 in Portland.

Word had already started to leak out via some of the clubs. On a Facebook post, Milwaukee’s The Rave stated the following. regarding their show this Thursday (15): “We are sorry to say that Machine Head will not be performing at this week’s Dethklok show. We apologize for the inconvenience.” Then St. Louis’ The Pageant had a similar tweet saying the band wouldn’t be playing on Sunday (18).

“I’ve been toughing out an inguinal hernia below my waistline since June of last year, and a few months ago got a second hernia in my nuts,” Flynn said in a statement. “What basically happens is my guts drop into my nuts, and it looks like I have a third testicle (man, I can hear the jokes already!) It hasn’t been that painful, and I’ve gone to the doctor a few times to take care of it, but he said after surgery I probably couldn’t sing for a few weeks, and since that wasn’t going to happen, I scheduled it for January when I had a break. Unfortunately, after the last few shows, my guts have been very swollen and hard to push back in. Yesterday, the pain was excruciating and I went to the emergency room last night. They said that I need surgery.

“I will be doing my damnedest to rejoin the tour in a couple weeks.

“Thanks to all the fans, bands, and crew for understanding. I’m determined to see you all soon and finish what has been a great freakin’ tour!”

While that’s unfortunate for Flynn (ouch), it means that fans of the other bands playing will probably get to hear a little more of them. And while it’s little consolation, at least the band’s live album, Machine F**king Head Live, is out today, so you can still hear a little of them.
