Kubrat Pulev is ready to challenge Anthony Joshua behind closed doors due to the globalcoronaviruscrisis.
The Bulgarian is due to take on the heavyweight world champion at the Tottenham Hotspur Stadium on June 20.
But with boxing in Britain suspended until at least May, there is little prospect of the fight taking place as scheduled.
Promoter Eddie Hearn has pencilled in July 25 as an alternative date – but even that may be unrealistic.
Pulev, therefore, is prepared to challenge the Brit without the atmosphere generated by 60,000 fight fans.
“I’m ready for June 20, July 25, whenever they say,” he said. “You see what the situation is, the whole world must adjust to it.
“There’s no problem (if the fight is) to be without spectators. Everyone would be at home, they can pay per view, so I don’t see any problem financially.
“The show could be lost a bit without fans but it can still happen. After all, it’s a world championship, which must take place.”
Pulev is currently training in the snow in Bulgaria as he awaits further instruction.
Hearn is set to cancel two further shows this week with Dillian Whyte’s clash against Alexander Povetkin on May 2 and Dereck Chisora’s meeting with Oleksandr Usyk on May 23 set to be postponed.
The British Boxing Board of Control released a statement on Monday which read: “Following further Government and Medical Authorities advice the British Boxing Board of Control has decided that the suspension of Boxing Tournaments under the BBBofC jurisdiction remains in place until the end of April when further consideration will be given.
“We will continue to follow Government and the Medical Authorities advice and keep the situation under review.
“The BBBofC would like to emphasise our thoughts are everyone affected by Covid-19.”
