Ozzy Osbourne fans had been circling May 27-31 on their calendars for the first-ever Ozzfiesta, an extravagant Mexican getaway week that was to take place at the Hard Rock Hotel in Riviera Maya, Mexico. But the event will not be happening this year, as Ozzy Osbourne is reportedly set to undergo surgery in May, leading to a conflict.

The event was scheduled to include performances not only by Osbourne, but also an individual acoustic set from Zakk Wylde as well as a full performance by Wylde's band Black Label Society. Ozzfiesta was also going to include a number of parties, a charity golf tournament and a comedy club featuring such comedians as Jim Norton and That Metal Show's Jim Florentine performing.

A statement from Cool Breeze Concerts, the promoter of the Ozzfiesta extravaganza, reads as follows:

Cool Breeze Concerts regret to inform you that Ozzfiesta is cancelled.
Like you, we were very excited about the event. However, Ozzy is having surgery, scheduled for May, following his South American tour. He requires at least four weeks of recovery time. We are very disappointed that we need to cancel.
We will be offering refunds which will be processed in the next 4-6 weeks. If you decide that you would still enjoy an all inclusive vacation at the Hard Rock, Riviera Maya, Mexico please send us an email, and we can make the arrangements.
We apologize for any inconvenience and hope that you understand the circumstances surrounding the cancellation.

The nature of Osbourne's surgery is not known, but the rocker is expected to be ready by the time Black Sabbath play their farewell show at Makuhari Messe at Ozzfest Japan on Nov. 22. Sharon Osbourne made the announcement for the farewell Sabbath appearance in a trailer promoting the event that surfaced this past weekend.

There has been no word of any other Black Sabbath dates or discussion of when a new album may be arriving, even though Ozzy spoke last fall of the band's desire to do one more tour and album.
