He thanked his family, fans, band and crew members and fellow metal pioneers Judas Priest.
“Never would I have imagined that my touring days would have ended this way,” Osbourne said. “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.”
Ticket refunds will be available at the point of purchase, the statement said.
Osbourne previously cancelled tour dates in Europe and North America in 2019 due to health problems, including a “bad fall” in which he said he injured vertebrae in his neck.
The singer, who enjoyed solo success after leaving Black Sabbath, announced in 2020 that he had been diagnosed with Parkinson’s disease, a nervous system disorder that affects movement.
Osbourne and the other three members of Black Sabbath were inducted into the Rock and Roll Hall of Fame in 2006. Osbourne and his family, including his wife, Sharon, and two of his three children were the stars of their own reality show called The Osbournes.
