Oleksandr Usyk will defend his IBF, IBO, WBO and WBA heavyweight titles against Britain's Daniel Dubois next month.
The match will take place at the Tarczynski Arena in Wroclaw, Poland, on August 26.
Usyk was expected to fight WBC world heavyweight champion Tyson Fury in a unification fight but negotiations fell through in March.
Dubois, 25, is the WBA (regular) heavyweight belt holder and mandatory challenger.
Former undisputed cruiserweight champion Usyk snatched the titles off Anthony Joshua in London in September 2021 and won the rematch in August last year in Saudi Arabia.
Dubois will be Usyk's second defence of his world heavyweight belts with the match-up announced on Twitter by Frank Warren's Queensbury Promotions.
Usyk, whose scheduled showdown with Tyson Fury at Wembley fell through due to contractual disputes, said simply on Instagram: "See you 26 August".
Londoner Dubois, nicknamed 'Dynamite', has won 19 of his 20 fights since turning professional in 2017, 18 by knockout, with one defeat, against fellow British heavyweight Joe Joyce in 2020.
Dubois suffered a fractured orbital bone and nerve damage to his left eye when stopped in the 10th round by Joyce, but has beaten four opponents since.
The smuggler
Eldarir had arrived at JFK in January 2020 with three suitcases, containing goods he valued at $300, when he was directed to a search area.
Officers found 41 gold artefacts among the bags, including amulets from a funerary set which prepared the deceased for the afterlife.
Also found was a cartouche of a Ptolemaic king on a relief that was originally part of a royal building or temple.
The largest single group of items found in Eldarir’s cases were 400 shabtis, or figurines.
Khouli conviction
Khouli smuggled items into the US by making false declarations to customs about the country of origin and value of the items.
According to Immigration and Customs Enforcement, he provided “false provenances which stated that [two] Egyptian antiquities were part of a collection assembled by Khouli's father in Israel in the 1960s” when in fact “Khouli acquired the Egyptian antiquities from other dealers”.
He was sentenced to one year of probation, six months of home confinement and 200 hours of community service in 2012 after admitting buying and smuggling Egyptian antiquities, including coffins, funerary boats and limestone figures.
For sale
A number of other items said to come from the collection of Ezeldeen Taha Eldarir are currently or recently for sale.
Their provenance is described in near identical terms as the British Museum shabti: bought from Salahaddin Sirmali, "authenticated and appraised" by Hossen Rashed, then imported to the US in 1948.
