It has been a summer of surgeries for Slipknot's members. A few months ago the band had to postpone some tour dates after Corey Taylor had spinal surgery. Now, guitarist Jim Root has gone under the knife for a disc replacement in his back. He posted a photo on Instagram of himself hooked up to an I.V. wearing spiffy hospital slippers and flipping the bird.

Root wrote, "Seems as if fractured vertebrae and hemorrhaged disks are an occupational hazard for metal bands. So. Early in the morning after Louder Than Life in Louisville I flew out for disk replacement surgery. Had the procedure this morning and other than being a bit sore and spun out from jet lag and Norco's it's all good."

He continues, "Although I won't be as 'mobile' onstage as before I'm looking very forward to the upcoming Knotfest shows and places we'll be going in between..." Read the complete post below.

Slipknot's next show is Knotfest Mexico on Oct. 16. After playing gigs in Peru and Colombia they'll head to New Zealand and Australia, followed by a concert in Taiwan on Nov. 3 and Knotfest Japan Nov. 5 and 6.

It's been awhile since I've posted... a quick update before I disappear again. First of all, many many thanks to all of you for the birthday wishes. Thank you. From the bottom of my heart I appreciate it. 2nd of all... seems as if fractured vertebrae and hemorrhaged disks are an occupational hazard for metal bands. So. Early in the morning after Louder Than Life in Louisville I flew out for disk replacement surgery. Had the procedure this morning and other than being a bit sore and spun out from jet lag and Norco's it's all good. Although I won't be as "mobile" onstage as before I'm looking very forward to the upcoming Knotfest shows and places we'll be going in between... And lastly. That wasn't quick. I spent way too much time typing all this out and most of you guys will lose interest and probably not even read the entire thing! Dicks. 😉 this message brought to you by Norco narcotics.
