ABU DHABI – Saturday’s championship bout between UFC middleweight titleholder Israel Adesanya and top contender Paulo Costa has clear historical significance, but the bout’s position in terms of true impact on the sport’s chronicles may only be clear in retrospect. Surprisingly, the UFC 253 headliner is just the second time in modern UFC history that two undefeated male fighters have squared off with a title on the line. The first such instance saw Lyoto Machida defeat Rashad Evans for the light heavyweight title in May 2009.
