Ozzy Osbourne has once again been forced to cancel upcoming tour dates of this “No More Tour 2” farewell tour due to health issues.

In a statement, Osbourne said, “I’m so thankful that everyone has been patient because I’ve had a sh*t year. Unfortunately, I won’t be able to get to Switzerland for treatment until April and the treatment takes six-eight weeks. I don’t want to start a tour and then cancel shows at the last minute, as it’s just not fair to the fans. I’d rather they get a refund now and when I do the North American tour down the road, everyone who bought a ticket for these shows will be the first ones in line to purchase tickets at that time.”

Fans will be able to get a refund from their point of purchase and will be eligible to get first access to tickets when new dates are announced.

Osbourne has been battling a number of health issues for over a year. During an interview with Good Morning America in January, Osbourne revealed he was diagnosed with Parkinson’s disease. Osbourne would later say in an interview with The Los Angeles Times that he was actually first diagnosed with Parkinson’s back in 2003.
