Slipknot were inching closer to the June 9 kickoff to their co-headlining summer tour with Marilyn Manson, but now the start of the trek will be delayed. Frontman Corey Taylor issued a message on Facebook, explaining he had to undergo "unplanned spinal surgery."

He states, "Regretfully, I'm sending this to our fans to inform you that we will be postponing the first couple of weeks of our upcoming U.S tour. Unfortunately, I had to undergo an unplanned spinal surgery. I am recovering nicely, and all went well! I need a little recovery time before hitting the stage. We will start the summer tour in Nashville on 6/28 and continue as previously scheduled. An update on the rescheduled dates will be available in the next few days. I hope you all understand and thanks for always having my back! Thank you, Corey."

The rigorous physical demands of the band's live performances have come at a toll over the years, but it is not certain if Taylor's issues stemmed from being onstage. Turntablist Sid Wilson is known for his epic stage dives, though he has broken his foot multiple times while indulging himself in the impressive feats, the latest occurring in October of last year. In 2008, he managed to complete a tour with casts on both feet after breaking them on the opening night of the Mayhem Festival.

The postponement will affect the first 12 dates of the tour, as listed below:
