Heavy-metal legend Ozzy Osbourne has cancelled his entire US No More Tours 2 farewell tour.
All tickets will be refunded and no make-up dates are planned - at least not for now, he said in a statement issued on Tuesday.
The reason for the cancellation is to enable the 71-year-old singer "to recover from various health issues he has faced over the past year", the statement said.
Osbourne's new album, Ordinary Man, is due out on February 21.
Osbourne announced in January that he has Parkinson's disease, although he more recently disclosed that he has been aware for years of his diagnosis.
"I'm so thankful that everyone has been patient because I've had a s**t year," Osbourne said in his statement. "Unfortunately, I won't be able to get to Switzerland for treatment until April and the treatment takes six-eight weeks."
Osbourne had originally been scheduled to perform his No More Tours 2 farewell show in San Diego in late 2018 at what was then then Mattress Firm Amphitheatre and is now North Island Credit Union Amphitheatre.
That show was postponed after he suffered an infection after undergoing hand surgery.
In April 2019, Osbourne cancelled all his tour dates for that year, including his July 2019 San Diego make-up concert, in order for him to recover from an injury he sustained in a fall while recovering from a bout of pneumonia.
Osbourne's now-cancelled 2020 US tour had been scheduled to begin on 27 May in Atlanta.
