Ozzy Osbourne has been forced to cancel the first four U.K. dates of his European "No More Tours 2" farewell tour after coming down with the flu.

The announcement was made via Judas Priest, who are opening for the Prince of Darkness on the run which was scheduled to kick off on Jan. 30 in Dublin, Ireland.

The band wrote on Instagram, "It is with great regret we have to announce that the first four UK shows on the Ozzy Osbourne/Judas Priest tour have been postponed due to Ozzy having a very bad case of flu - therefore Dublin, Nottingham, Manchester and Newcastle will be rescheduled at a later date - details to follow once finalised - we are very sorry that this has happened and to disappoint so many fans - we wish Ozzy well and look forward to the Glasgow, Birmingham and London shows together - and to the rescheduled ones in the future."

These four concerts (see remaining dates here) were the first four scheduled shows for Osbourne in 2019 after celebrating the end of 2018 with a New Year's Eve edition of Ozzfest. The singer was joined by Rob Zombie, Marilyn Manson, Jonathan Davis and Body Count at The Forum in Los Angeles.

This news only adds to the legendary singer's recent medical woes. On Jan. 24, Ozzy posted an image showing a burst blood vessel in his eye as a result from coughing. It is not known if he was battling the flu during that time.

We wish Ozzy a swift recovery.
