Slipknot were forced to delay their co-headlining summer tour with Marilyn Manson due to frontman Corey Taylor undergoing and “unplanned spinal surgery.”

“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,” he wrote on Facebook. “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.”

Taylor has since checked in via Twitter with the following update on his condition:

Neck Update: follow-up appt w/ Dr was great! For now, no headbanging, jumping. But I'll sing my ass off. Back to 90% 4-6 months, 100%/year.
