Heavy metal icon Ozzy Osbourne is apparently suffering from a sudden illness, according to his concert promoter.

The unexpected bug forced Osbourne to postpone Sunday night's show in Reno, Nev.

It's not clear what's ailing the 62-year-old rocker, but the concert was rescheduled for April.

Osbourne is currently on the U.S. leg of his "Scream" tour.
