Ozzy Osbourne has announced that he has cancelled the North American portion of his “No More Tours 2” tour.

“I’m so thankful that everyone has been patient because I’ve had a sh*t year,” Osbourne said in a statement. “Unfortunately, I won’t be able to get to Switzerland for treatment until April and the treatment takes six to 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.”

Full refunds for tickets and fees will be available at the point of purchase.
