Dillian Whyte will seek an exemption to quarantine so he can stay at his training camp in Portugal until a week before his clash with Alexander Povetkin.
The British heavyweight is due to face the Russian at Matchroom Fight Camp in Eddie Hearn’s back garden on August 22.
But Whyte is currently preparing for the clash in Portugal, which is not part of the UK government’s travel corridor.
That means the heavyweight challenger would need to self-isolate for 14 days on his return to these shores.
But promoter Eddie Hearn is hoping to avoid that situation with an exemption.
He said: “We are in discussions about an exemption; I believe there will be a number of exemptions for events published this week and we’re on the list of requests.
“If not, there’s nothing he can do and he’ll have to come back two weeks early.”
Ireland’s Katie Taylor also defends her four lightweight titles against Belgium’s Delfine Persoon on the same card but the Bray woman trains in America so will also need an exemption.
Hearn added: “It affects Whyte, Katie Taylor because she’s training in America, and Alexander Povetkin. He’s already booked to come, he’s up for it.
“It’s not just a case of not coming back till fight week, you have to be tested before.
“It’s more of a ballache to not come back because you have to be tested before you fly, tested when you land, tested five days after that then on fight week.”
