Black Sabbath frontman Ozzy Osbourne is retiring from touring because he says he is "not physically capable" of dealing with the travel.
The 74-year-old "No More Tears" and "Crazy Train" singer made the announcement Tuesday, canceling his upcoming tour stops while marking four years since a major accident that damaged his spine and resulted in a life-altering operation last year that removed and realigned pins in his neck and back.
"My one and only purpose during this time has been to get back on stage. 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," the Rock & Roll Hall of Famer said in a statement posted on social media.
