Eddie Hearn says Anthony Joshua will fight in any location, even if it is behind closed doors or at the promoter's home.
Joshua, who was set to face Kubrat Pulev in June and has also agreed to a two-fight deal with Tyson Fury, has not fought since regaining his WBA, IFB and WBO heavyweight belts from Andy Ruiz Jr in Saudi Arabia in December.
Hearn, meanwhile, has constructed a ring in the grounds of his estate in Essex, with the aim for boxing to return from the coronavirus-enforced break with an event called 'Fight Camp'.
The event is set to start next month, and though Joshua is not currently slated to be involved, Hearn is adamant the 30-year-old is willing to fight anywhere.
"Joshua would fight here [at Hearn's home], no problem," Hearn told BBC Sport.
"If we were faced with the option of having no fans for an Anthony Joshua fight, we would still look to go ahead. He's spent a lot of time training out here in this garden so he would have no problem fighting here himself.
"He was here a couple of weeks ago. He loves to fight, to box and it's not just about fighting in a huge arena – Wembley Stadium, Madison Square Garden – it's about boxing.
"We want him to be in front of crowds. But for his career, for his development, he needs to fight this year."
Hearn is also confident Joshua's planned fight with Pulev will go ahead in 2020.
"Of course fighters want to earn as much money as possible but they also need to develop as fighters and I think the Kubrat Pulev fight is a good, solid, tough fight for him and I am almost certain you will see that fight this year," Hearn added.
"He wants to improve as a fighter and he will do it anywhere, anytime."
