World heavyweight title

The all-British fight had looked set to take place in Saudi Arabia in August.

But it fell through when Deontay Wilder's team won an arbitration hearing stating the American had a right to a third fight with Fury.

"It might not be December or even next year," said Bunce.

The much anticipated fight between Fury and Joshua would have seen the pair contest all four world titles for the first time in the sport's history.

Fury is the WBC champion while Joshua has the WBO, WBA and IBF belts.

Both men had to climb off the canvas in an 11-round epic in front of 90,000 at Wembley, but Joshua had the lasting power to pummel Klitschko late on and add the WBA title and less revered IBO belt to his IBF crown.

Klitschko recovered from tasting canvas in the fifth to send Joshua to a first career knockdown a round later, although the Ukrainian veteran could not capitalise and the Brit was able to recover ahead of his late onslaught.
