After fan speculation, Taylor cleared the air, stating on Twitter, "Basically broke my neck a while back and didn't realize it." He elaborated that he had two discs replaced as well as work done on his vertebrae. After receiving messages regarding his decision to quit smoking as fans linked this to the surgery, Taylor sent out a Tweet dismissing this notion, exclaiming, "Enough [with] the conspiracy theories.

Both Tweets can be seen below along with a picture of Taylor smiling in a neck brace.

The affected dates ranged from the stops originally set between June 9 in Salt Lake City, Utah through June 26 in The Woodlands, Texas. Slipknot's tour with Manson will now kick off June 28 in Nashville, Tenn. Of Mice and Men will be the opening act on the trek.

After the conclusion of their summer trek, Slipknot will break ground in late September as Ozzfest and Knotfest collide over the course of the Sept. 24 and 25 weekend.
