Anthony Joshua is bidding to become a three-time heavyweight champion when he faces Oleksandr Usyk this summer.
In September 2021, Usyk outclassed Joshua to win on points in London and became a two-weight world champion - and just the second after Evander Holyfield to unify both the cruiserweight and heavyweight divisions.
The Ukrainian southpaw will now face Joshua once again and below, we take a look at everything we know ahead of the blockbuster.
When will the fight take place?
It was originally pencilled in for July 23 but negotiations between both teams took longer than expected due to bids from overseas countries to host the fight as well as the broadcasting rights.
The second fight will take place in Jeddah, Saudi Arabia and August 20 is the chosen date.
Will it be a UK-friendly timezone?
While Saudi Arabia is a seven-hour flight from the UK, they are only two hours ahead of British Summer Time.
When Joshua previously fought in Saudi Arabia against Andy Ruiz Jr, the main event happened at 21:00 BST. Expect a similar time.
How can I watch Usyk v Joshua 2?
Anthony Joshua signed a multi-fight deal with DAZN UK and it is believed to be worth eight figures.
The heavyweight left Sky Sports after an eight-year association with them and not only will he fight on the platform, he will become a stakeholder in the company.
AJ said: "I am entering a new phase in my career with a new training environment, new coaches and now a new broadcaster.
"Negotiations at this level take time so I am pleased to have it all wrapped up and now I can fully focus on giving the fans and DAZN what they want, knockouts in the glamour division.
"I've been working with DAZN and following its progress for a long time.
"We have enjoyed a really successful partnership in the US for many years and I know the team and understand the passion and drive of the business.
"DAZN's vision and passion to innovate is what attracted me to the partnership.
"They are leading the digital landscape in sport and the future of sports broadcasting. I am really looking forward to a long and successful partnership."
His first fight on the OTT streaming service provider however, will not be on there as the deal did not include this fight.
Sky Sports won with the highest bid and will stage it on Sky Sports Box Office at £24.95.
How can I get tickets?
Matchroom Boxing recently agreed a deal to work with ticket supplier Stage Front from July 1.
Tickets online will be confirmed in due course.
Who will be on the undercard?
Callum Smith will be on the undercard and is set to face France's Mathieu Bauderlique in a final eliminator for the WBC light heavyweight title.
Artur Beterbiev currently holds the green-and-gold belt and is the unified champion at 175bs. He holds the WBC, IBF and WBO titles and will face UK's Anthony Yarde next.
Eddie Hearn has confirmed that he expects local talent from Saudi Arabia to fight on the card as well as at least one female fight. The remainder of the undercard is likely to be confirmed at the start of August.
