And the world heavyweight champions are in line for a humongous pay day with the Middle East country forking out a staggering amount of money to stage the fight.
Saudi Arabia is paying around $150 million to land the all-British bout - with Joshua and Fury to split the massive site fee payment.
So, that's $75 million a piece with further reports claiming each fighter should easily clear $100 million based on additional revenue.
The WBA (super), IBF and WBO world champion is training in the UK while the WBC title holder has based himself in America with head coach SugarHill Steward.

And David Haye has backed 'AJ' to stop the 'Gypsy King' in the early rounds.
He told Press Association: "I like the dedication of Joshua and I think he has a good chance of winning it early.
"People think I'm crazy but that's just the way I see it. I loved his fight against Wladimir Klitschko - he took his licks and got back up and showed the heart of a champion.
"I think it's a great fight and I really see it being won by stoppage. I'm just so glad we're so close to seeing it happen."
On Joshua's first professional defeat to Andy Ruiz Jr, Haye added: "Joshua waded in in his first fight against Andy Ruiz Jr and learned a hard lesson.
"You've got to soften your man up and pick your punches - just because you have the ability to knock someone out doesn't give you the divine right to do so.
"Tyson isn't so much of a one-punch specialist. He puts his punches together and his style is that if you throw big looping shots at him he'll make you look silly.
"But AJ throws hard, compact punches and he puts them together well. I don't see this fight going smoothly for Fury at all."
