Chantelle Cameron to defend three titles against Mikaela Mayer on Jake Paul card

Chantelle Cameron will defend her three super welterweight titles against Mikaela Mayer on Dec. 24 in Dubai, Most Valuable Promotions announced Friday. The 10-round rematch will be the co-main event on the Jake Paul–Cédric Doumbé card at Coca-Cola Arena.

Cameron (23-1, eight knockouts) won their first fight in Birmingham, England, on Aug. 29, taking Mayer’s WBA and WBC belts to add to her WBO title at 154 pounds. Two judges scored the fight 97-93 and the third had it 96-94, all for Cameron. She had won the vacant WBO belt against Michaela Kotaskova in April.

“We agreed to the rematch before the first fight, so we both kept our word,” Cameron said in a statement released by the promoter.

Mayer, a 2016 U.S. Olympian, has won titles in three weight classes and remains the WBO champion at 147 pounds. She beat Canada’s Mary Spencer in Montreal in October 2025 to win three belts at 154 pounds before losing to Cameron. Cameron previously held all four major belts at 140 pounds, beating Jessica McCaskill to become undisputed in 2022.

Friday’s announcement also added American Olympian Jahmal Harvey, who is 5-0 with four knockouts, against Scotland’s Craig Morgan in an eight-round lightweight fight. Former UFC fighters Alistair Overeem and Jimi Manuwa were added to the card Thursday for a six-round heavyweight boxing match.

Paul and Doumbé are scheduled to meet in an eight-round cruiserweight bout. Tickets go on sale to the general public Sunday at 3 a.m. ET. The promoter’s announcement gave no broadcast details.
