Ozzy Osbourne is not ready to get back on stage.

On Monday, the Black Sabbath rocker announced that he made the “painful decision” to pull out of his performance at Power Trip festival in October.

“My original plan was to return to the stage in the summer of 2024, and when the offer to do this show came in, I optimistically moved forward,” Osbourne, 74, wrote on Instagram. “Unfortunately, my body is telling me that I’m just not ready yet and I am much too proud to have the first show that I do in nearly five years be half-assed.”

He continued, “The band that will be replacing me on Power Tripwill be announced shortly. They are personal friends of mine and I can promise that you will not be disappointed.”

“Above all, I want to thank my fans, my band, and my crew for their unconditional loyalty and continual support. I love you all and I will see you soon,” he concluded.

In March, Osbourne informed fans that he was canceling all his then-upcoming U.K. and European tour dates due to his damaged spine.

“My singing voice is fine. However, after three operations, stem cell treatments, endless physical therapy sessions, and most recently groundbreaking Cybernics (HAL) Treatment, my body is still physically weak,” Osbourne wrote on Instagram at the time.

“Never would I have imagined that my touring days would have ended this way,” he added. “My team is currently coming up with ideas for where I will be able to perform without having to travel from city to city and country to country.”
