The fight will take place on the Burj Al Arab Hotel helipad on Saturday night, 700ft above sea level in what will be an extravagant affair even by Mayweather’s standards.
There will be just 20 spectators watching on, each having spent in the region of £150,000 on tickets that were only available as NFTs.
It’s Mayweather’s first bout since he fought YouTuber Logan Paul in Miami last June, in an exhibition that lasted the full eight rounds despite the enormous gulf in ability.
He now faces Moore, who at 42 is three years younger than Mayweather. Moore’s last professional fight was in 2016, with the featherweight’s record standing at 18-0-1.
The pair began sparring together in 2012, while Moore has in the past been coached by Mayweather’s uncle Roger.
On the undercard, former UFC star Anderson Silva is in action against Bruno Machado. Silva had two boxing fights last year, beating Julio Cesar Chavez Jr and then knocking out Tito Ortiz in a round.
Badou Jack, a former world champion at super-middleweight and light-heavyweight, fights Hany Atiyo, an Egyptian with four defeats in his 19 professional bouts. Atiyo has fought once in the last six years.
Delfine Persoon, who many believed should have got the decision over Katie Taylor in 2019 on the Anthony Joshua vs Andy Ruiz undercard at Madison Square Garden, faces Elhem Mekhaled.

Mayweather vs Moore prediction
Both fighters to make a lot of money. Beyond that, it depends entirely on what Mayweather wants from the bout. He may decide to just coast through the eight rounds, as he did against Paul last year, or he could want to put on more of a show.
Mayweather has claimed in the build-up to this weekend’s fight that it will be an entertaining affair, with Moore possessing a more ambitious attitude than Paul did.
He said: “Don will come to fight. It’s a little different, Don is going to come to fight and may the best man win.
“Whereas at the Hard Rock Stadium, Logan Paul talked a good game but didn’t come to fight, he came to hold.
“So he’s coming to fight, I’m coming to fight. Eight rounds, from start to finish, it’s going to be explosive.”
