British former world heavyweight champions Tyson Fury, 38, and Anthony Joshua, 36, announced at a London news conference that they will finally fight on December 11 in Cardiff, ending a decade of failed negotiations, contract disputes and rival promoters' wrangling. The bout, streamed globally by Netflix and reportedly worth a $200m purse split, is billed as a collaboration between Saudi official Turki Alshikh's The Ring magazine and UFC (the US mixed martial arts promotion) owner Dana White, whose role Joshua's promoter Eddie Hearn had disputed. It matters as the biggest all-British fight in the sport's history, though questions remain over whether it comes too late in both careers, with each man having since lost to Ukraine's Oleksandr Usyk.
