Anthony Joshua's world title fight with Wladimir Klitschko has been postponed due to the Ukrainian former champion suffering an injury in training camp.
Eddie Hearn confirmed Joshua will go ahead with a title defence in Manchester on December 10 against an as yet unnamed opponent and will have to wait until next year for a potential bout with Klitschko.
The injury is reportedly to the calf of the former unified world heavyweight champion and ends weeks of speculation about a showdown between the pair.
The fight had previously been on hold due to the WBA deliberating whether or not their recently vacated title would be on the line.
Klitschko had expressed that he would not take on Joshua if the WBA belt he lost to Tyson Fury last year would not be on the line.
Joshua's IBF strap was also won by Fury on that night but was vacated just weeks afterward as 'The Gypsy King' refused to defend it against the mandatory challenger.
His WBO and WBA belts have since also been vacated due to his well-documented personal issues and his boxing licence was suspended just last week by the British Boxing Board of Control.
Matchroom Sport's Eddie Hearn commented saying:
"We've been in deep negotiations for a few weeks now waiting on the decision from the WBA.
"I was made aware that Wladimir picked up a minor injury late last week but regardless of that, with just over six weeks to go til December 10, it's unrealistic to put together a fight of this magnitude and give it the full build up it deserves.
"There will be an official announcement on Joshua v Klitschko coming very soon but for now we are seeking a new foe for December 10 and building a huge card for Manchester."
Hearn must now find Joshua a new opponent but that task may be trickier now that IBF mandatory challenger Joseph Parker seems set to go down the WBO route.
Kubrat Pulev and Bryant Jennings may be possible opponents for the unbeaten Brit and there is no doubt that David Price's name will be thrown around too after he called Joshua out last week.
