The eagerly anticipated world heavyweight title fight between Wladimir Klitschko and Tyson Fury has been postponed.
The world champion (63-3-53KO) has suffered a calf injury in training and will be unable to fight on October 24, with the 39-year-old looking like he will have to abstain from physical activity for a number of weeks.
German physician Dr Hans-Wilhelm Muller-Wohlfahrt told Sky Sports: "The clinical and MRI-examination showed a partial musculotendinous tear of the left calf. The boxing fight planned for October 24 should be postponed for an indefinite period of time.

"Due to this injury we strictly recommend ceasing athletic activity in the next weeks."
Klitschko also spoke to Sky Sports and said: "I apologise to my opponent, who has spent many weeks preparing for this fight. I will do my very best to recover as fast as possible."
It was an apology that the unbeaten Fury (24-0-18KO) didn't take lightly when he posted on Twitter
"Well its official, Klitschko has pull out of the fight with an injury in his leg, its a bit funny as I predicted this would happen," the Mancunian said.
It is a postponement that will disappoint many boxing fans, especially after the colourful and downright weird build-up provided by Fury. Klitschko is no doubt the biggest test for the English heavyweight to date.
This is not the first time that the Mancunian has seen a big fight called off for no fault of his own. His scheduled clash with fellow Brit David Haye was called off twice in late 2013 and early 2014, with Haye suffering a cut and a shoulder injury.
The heavyweight contender slammed Haye at the time and accused him of running scared of him, something he believes Klitschko, who hasn't been beaten for 11 years, is doing after being intimidated at the fight's UK press conference on Wednesday.
The fight is due to be rescheduled next week, but for now Fury has little solace.
