Most Valuable Promotions confirmed the addition of the fight to the card, which is headlined by Jake Paul's return to the ring against French kickboxer Cedric Doumbe. The two women previously met in August, where Cameron secured a unanimous decision victory.

That win allowed the 35-year-old Briton to add the WBA and WBC titles to her existing WBO belt. Following the conclusion of their first encounter, the 36-year-old American expressed her disagreement with the judges' decision, leading to a rematch agreement.

Cameron enters the contest with a professional record of 23 wins and one defeat, which came against Katie Taylor in 2023. She stated that the rematch was planned before their first meeting and expressed excitement about performing on a major stage.

Mayer, who holds 22 wins from 25 professional bouts, has been focused on correcting the errors from her previous performance. She remains confident in her ability to reclaim the world titles when the two fighters meet again in December.

The event marks Paul's first appearance since his knockout loss to Anthony Joshua last December. The undercard also features a heavyweight boxing debut for former UFC fighter Alistair Overeem, who is scheduled to face Jimi Manuwa.
