Ozzy Osbourne has been forced to postpone the first four shows on his upcoming U.K. tour due to the singer having a very bad case of flu. The concerts in Dublin on January 30th, Nottingham on February 1st, Manchester on February 3rd and Newcastle on February 5th will be rescheduled at a later date. Details will follow once they have been finalized. The trek will now kick off on February 7th in Glasgow.

The news of the postponement comes just days after Ozzy said on social media that he coughed so hard that he burst a blood vessel in his eye.

This is the second time in the past year that an illness has forced the singer to call off a round of dates. Last October, Ozzy contracted a staph infection that required him to have surgery on his hand and resulted in him canceling several shows.

The European leg of Ozzy's "No More Tours 2" is being billed as the 70-year-old singer's official farewell to more than five decades of touring, although he still intends to occasionally perform live in far more selective fashion.
