Ozzy Osbourne is set to undergo a "very major operation" on Monday, June 13.
The Black Sabbath frontman's wife, Sharon Osbourne, shared the news this week during an episode of her U.K. talk show The Talk.
"It's really gonna determine the rest of his life," Sharon said of the procedure.
Sharon did not speak on the nature of the operation, but Ozzy, 73, told Classic Rock magazine in an interview published in May that he was "waiting on some more surgery" on his neck. Ozzy suffered a fall in 2019, which aggravated injuries he sustained in a 2003 ATV accident.
Beyond that, Ozzy has been battling a number of health issues over the past few years. Prior to the 2019 fall, he'd been hospitalized with a bad case of pneumonia, and in early 2020, he revealed he'd been diagnosed with Parkinson's disease.
In April of this year, Ozzy tested positive for COVID-19.
