Just two days on from a press conference that had the whole world talking about the fight, Klitschko suffered a tear in his calf and had to make the announcement that the fight will be delayed.
The 40 year-old told German newspaper Bild that the contest will go ahead as planned once he fully recovers from the ailment and issued an apology to challenger Fury in the process.
“Of course I’m mad about this and sorry for my fans, but also for my opponent Tyson Fury,” said Klitschko
Manager Bernd Boente added: “Next week, we will announce when the fight will be rescheduled. We will definitely stay in Dusseldorf and the tickets that have already been sold remain valid.
Fury, 27, has been involved in similar circumstances before when compatriot David Haye pulled out of two bouts before his extended time out of the ring, although this time it should be just a matter of waiting for the fight to be given another date.
Klitschko v Fury was set to take place on October 24 at the ESPRIT Arena in Dusseldorf, Germany before the Ukrainian broke the news on Friday.
