The first, Anthony Joshua vs. Otto Wallin was contested between English former WBA (Super), IBF, WBO, and IBO heavyweight champion Anthony Joshua and Swedish WBA inter-continental heavyweight champion Otto Wallin.

The second, Deontay Wilder vs. Joseph Parker, was contested between American former WBC heavyweight champion Deontay Wilder and New Zealand IBF and WBO inter-continental heavyweight champion Joseph Parker.

In October 2023, it was reported that a bout between Tyson Fury and Oleksandr Usyk was being targeted for 23 December in Saudi Arabia with Anthony Joshua and Deontay Wilder serving as the co-feature.

[7] The bill featured the number one ranked heavyweight contenders from all four main boxing sanctioning bodies Deontay Wilder (WBC/WBA), Filip Hrgović (IBF) and Anthony Joshua (WBO).

Former world title challenger Daniel Dubois (WBC:14th WBA:7th IBF/WBO:8th) scored a dramatic stoppage of previously undefeated Jarrell Miller (WBA:6th) with only 10 seconds left in the final round.

The penultimate bout on the card saw former world champions Deontay Wilder and Joseph Parker faceoff for the WBO Inter-Continental and vacant WBC International heavyweight titles Wilder entered the ring having boxed just three minutes in the past two years, whereas Parker had fought three times already in 2023.

After multiple rounds of calculated pressure punching, Joshua hurt Wallin with a hard left hook in the 5th.

[12] With Wilder's one sided defeat, plans for a showdown with Joshua were dropped and speculation moved towards a bout with either Filip Hrgović or Zhilei Zhang.
