The winner would become the mandatory challenger for unified IBF, WBA and Ring light heavyweight champion Dmitry Bivol.

Wallace is ranked No. 2 by the IBF and brings a 17-1 (13 KOs) record into the bout, while Whittaker sits at No. 3.

Since winning silver at the Tokyo Olympics, the unbeaten 29-year-old Whittaker has become one of British boxing’s most heavily scrutinized figures. He has won four straight by stoppage, extending that streak in June with a second-round knockout of Richard Rivera to retain his WBC Silver light heavyweight title. Before that, he scored early knockout victories over Braian Nahuel Suarez and Benjamin Gavazi, along with a second-round technical knockout of Liam Cameron in their April 2025 rematch in Birmingham.

A victory over Wallace would move Whittaker within one fight of a world title opportunity against Bivol, who remains the division’s unified champion. The bout has not been officially announced.

Wallace would represent the toughest opponent of Whittaker’s career. A victory would strengthen his case as a legitimate world-title contender and secure his place as Bivol’s mandatory challenger.
