Probellum will host a historic world championship double-header at the Coca-Cola Arena in Dubai on Saturday, December 11 with Probellum: Revolution – as Sunny Edwards defends his IBF flyweight title against Jayson Mama and John Riel Casimero puts his WBO bantamweight title on the line against the UK’s Paul Butler. The event brings together some of the very best fighters from around the world in what is sure to be an action-packed night of boxing. Undefeated Edwards (16-0, 4 knockouts) makes the first defense of his world title, taking on his mandatory challenger Mama (16-0, 9 knockouts), after the two men were originally set to meet in September in the UK before an injury postponed the clash. Casimero (31-4, 21 knockouts) is back following his victory over Guillermo Rigondeaux in August, now squaring off with mandatory challenger Butler (33-2, 15 knockouts). Casimero is one of the most devastating punchers in the division who looks to keep his momentum going in his third world championship defense.
