The big December event in Saudi Arabia was finalized earlier today at the official press conference.

On December 23 in Riyadh, Saudi Arabia - a big eight fight card will play out with numerous key heavyweight fights from top to bottom.

Heading up the card is a doubleheader, which features former two-time heavyweight champion Anthony Joshua taking on veteran contender Otto Wallin.

Joshua will be fighting for the third time in 2023. And Wallin, who suffered his sole defeat with a decision loss to Tyson Fury in 2019, will look to continue his winning streak after a recent victory over Murat Gassiev.

In the other co-main event, a battle of former world champions with Deontay Wilder returning for the first time since October 2022 to battle Joseph Parker. Last month, Parker demolished Simon Kean in three rounds.

Should Wilder and Joshua win their respective fights, there is a good chance they will collide in 2024.

Heavyweight Daniel Dubois will attempt to bounce back from his August loss to unified champion Oleksandr Usyk, as he takes on undefeated Jarrell Miller.

WBA light heavyweight champion Dmitry Bivol will return for the first time since last December's win over Gilberto Ramirez, when he takes on top contender Lyndon Arthur of the UK.
