System Of A Down will take over the headlining slot, according to www.ozzy.com. Ozzy Osbournewill return to the tour in Denver on August 22.

“This has been one of the hardest decisions I’ve had to make and I’m hoping that my fans will understand,” Ozzy Osbourne said on his website. “Ozzfest must continue with or without me since it’s Sharon’s baby. I want to thank all the bands on Ozzfest and my crew for all their love and support, especially System Of A Down.”

On the dates that Ozzy Osbourne is not performing, Sharon has arranged for all fans attending Ozzfest 2002 to receive a free “special treat” from the food concessions at each show.
