Wladimir Klitschko's scheduled title fight against Britain's Tyson Fury in Dusseldorf next month has been postponed because of an injury to the world heavyweight champion, organisers announced.

Klitschko was due to meet Fury in Dusseldorf on October 24 for the WBA, WBO and IBF titles, but has pulled out after he tore a tendon in his left calf while training on Thursday.

A new date for the fight will be announced next week.

"I was looking forward to this fight very much. I know that a lot of fans have already organized their trips to support me in Düsseldorf," said Klitschko.

"I am so sorry that I am not able to fight on October 24. I also apologize to my opponent, who has spent many weeks preparing for this fight. I will do my very best to recover as fast as possible."

Klitschko, 39, has sought advice from renowned German sports doctor Hans-Wilhelm Mueller-Wohlfahrt, who simply recommended the fight be "postponed for an indefinite period of time."
