Youtuber-turned-fighter Jake Paul will face former reality star and light-heavy Tommy Fury in an eight-round cruiserweight bout at the Amalie Arena in Tampa, Florida, on December 18.
The duo have been jousting for months on social media, but now the battle will happen inside the ring in an officially sanctioned bout.
Though Fury has the more legitimate boxing background and pedigree, this fight represents the toughest test for both men to date in their fledgling pro careers.
Paul (4-0, 3 KOs) was last seen decisioning former UFC champion Tyron Woodley in August whilst Fury (7-0, 4 KOs) outscored the winless Anthony Taylor on the same bill.
