On Friday, British Heavy Metal icon OZZY Osbourne was seen for the first time since announcing retiring from touring.
Black Sabbath icon looked frail and he used a walking assisting device.
Announcing the news on Instagram, Osbourne said in his statement: "This is probably one of the hardest things I've ever had to share with my loyal fans.
"As you may know, four years ago, this month, I had a major accident, where I damaged my spine.
"My one and only purpose during this time has been to get back on stage.
"2My 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."
"I am honestly humbled by the way you've all patiently held onto your tickets for all this time, but in all good conscience, I have now come to the realisation that I'm not physically capable of doing my upcoming European/ UK tour dates, as I know I couldn't deal with the travel required.
