Bob Arum is confident a third bout between Tyson Fury and Deontay Wilder can take place at end of the year with spectators, with Macau and Australia floated as potential options to stage the fight.
The first meeting between the two ended in a thrilling and controversial draw in December 2018, before Fury claimed the WBC heavyweight title from Wilder with a seven-round demolition in Las Vegas in February.
A third meeting had initially been set to take place in July, but the coronavirus pandemic forced a postponement.
Talk has since turned to a unification bout between Fury and British compatriot Anthony Joshua, who holds the WBA, WBO and IBF belts and saw his scheduled fight with Kubrat Pulev delayed due to the COVID-19 health crisis.
However, the completion of the trilogy with Wilder still appears to be the focus for promoter Arum.
"When we postponed the fight in July we punted it to October," he told Sky Sports. "I then called Fury and told him to forget about October. We'll try to do it in November or December. We are moving ahead.
"Maybe Macau, which needs to attract customers and has tremendous protocols. They have had, for months now, no cases of coronavirus.
"There are six big casino properties in Macau.
"We've talked to them. They're ready to put up money for the Fury fight against Wilder in November or December. We are waiting to see if the authorities in Macau will allow an event with full spectators in November or December.
"Our friends in Australia are talking about doing this fight, probably in Sydney. That's a possibility."
Arum also talked up the possibility of the fight again being held in Las Vegas, where there is a new potential venue in Allegiant Stadium, home of the Las Vegas Raiders.
"Maybe we can do it with a full attendance at the new stadium in Vegas of the Raiders," Arum added. "Maybe we could do it with 20,000 or 30,000 people [later in the year].
"I can't tell you where, but I'm pretty sure we'll get this event on in November or December.
"We're not sleeping. We're working hard to get it done."
