Ozzy Osbourne has cancelled his Thursday concert at the Wolstein Center in Cleveland "due to an unforeseen personal family matter," according to a news release.

The show will not be rescheduled because of scheduling conflicts.

Refunds are available at the point of purchase.

"Ozzy apologizes for the inconvenience" to his fans, the release said.
