It is with great regret that Slayer announces the postponement of its 'Canadian Carnage' tour with Megadeth, which was due to begin on November 8. In addition, the band announces the postponement of its appearance on 'Jimmy Kimmel Live,' which had been set for this Wednesday, November 4. More information will be released shortly regarding the rescheduling of the Canadian dates, as well as the 'Kimmel' appearance.

Slayer's Tom Araya is currently under the care of a specialist for a back injury, thought to be related to his on-stage activity, and the physician has ordered an immediate surgical procedure to take place in Texas today (Tuesday) morning.

"What is foremost in our minds right now is that Tom do whatever he needs to to get this taken care of," said Slayer's Kerry King.

"While all four of us are disappointed that we won't be able to see through all of our commitments set for the next few weeks, the most important thing is Tom's health. We thank the fans in Canada and here in L.A., the Megadeth camp, and everyone associated with 'Jimmy Kimmel Live' for their understanding. We look forward to seeing you all soon."

Slayer's 'World Painted Blood' is released today, November 3.
