On July 7, 2018, Daniel Cormier knocked out Stipe Miocic at UFC 226 to become the UFC heavyweight champion, marking his achievement as the second fighter in UFC history to hold two division titles simultaneously. At 39 years old, Cormier joined an elite group of ten fighters who have been two-division champions and successfully defended belts in both weight classes. This victory was the first chapter in one of the UFC's most notable trilogies and solidified Cormier's status as one of the sport's greatest competitors.
