Oleksandr Usyk has added reinforcements to his team.

The two-division and reigning unified heavyweight titlist has entered an agreement with Saudi Arabia-based Skill Challenge Promotions (SCP). The deal was formally announced Saturday via social media, following a week-long tease by company CEO Amer Abdallah of a big signing on the way for the upstart promotional outfit.

Usyk (20-0, 13KOs) joins three-division and reigning WBC cruiserweight titlist Badou Jack (28-3-3, 17KOs) and unbeaten prospect Ziyad Almaayouf (3-0, 1KO) on the intimate but growing roster.

The move will not directly impact Usyk’s already scheduled WBA, IBF and WBO heavyweight titlist defense versus London’s Daniel Dubois (19-1, 18KOs), which will take place August 26 in Wroclaw, Poland. Alex Krassyuk, Usyk’s career-long home promoter (K2 Promotions-Ukraine) and business manager, secured the rights to the WBA title consolidation bout after winning a May 25 purse bid.

Where the significance of Usyk signing with SCP—who also does business as Skills Challenge Entertainment—comes into play is for the potential superfight that lies ahead.

Talks died earlier this year of an undisputed heavyweight championship between Usyk and reigning lineal/WBC king Tyson Fury (33-0-1, 24KOs). However, it was since revealed that SCP plans to stage a blockbuster heavyweight event featuring Fury-Usyk and a potential Deontay Wilder-Anthony Joshua fight later this December in Saudi Arabia.

A fight with Fury previously required Usyk to take the very short end of a purse split. It perhaps still rings true, though signing directly with the promoter funding such an event greatly increases his negotiating power.

“It’s a great opportunity to bring the biggest fight in heavyweight history to the boxing fans of the whole world," noted Usyk. "Tyson Fury doesn’t want this fight, but we will make it.”

Usyk won a Gold medal for Ukraine during the 2012 London Olympics and remains high among the best pound-for-pound fighters in the world. His first title claim came in a September 2016 win over then-unbeaten WBO titlist Krzysztof Glowacki. Usyk fully unified the division after winning the World Boxing Super Series cruiserweight tournament with wins over then-unbeaten titlists Mairis Briedis (WBC) and Murat Gassiev (WBA/IBF) in 2018.

A November 2018 knockout win over former titlist Tony Bellew in November 2018 marked Usyk’s final cruiserweight fight. Four wins have followed at heavyweight, including back-to-back victories over Anthony Joshua to win and defend the WBA, IBF and WBO titles. Their rematch last August 20 took place in Jeddah, Saudi Arabia. Skills Challenge Entertainment co-promoted the event along with Eddie Hearn’s Matchroom Boxing.
