The Black Sabbath show set for tonight at the Saddledome has been postponed, due to frontman Ozzy Osbourne coming down with a serious case of sinusitis – better known as a sinus infection.

Currently traveling around the world on their final tour – fittingly called The End – Black Sabbath have announced the postponement of shows in Calgary and Edmonton, with more details on the way.

More on this as it develops.
