Oleksandr Usyk vs. Tyson Fury takeaways: Usyk writing his own history; expect a different Fury in rematch

The first undisputed heavyweight title fight in 25 years did not disappoint when these two future Hall of Famers linked up

For the first time in the four-belt era, the undisputed heavyweight boxing championship was at stake on Saturday as Oleksandr Usyk and Tyson Fury put on an instant classic in Saudi Arabia. 

Usyk (22-0, 14 KOs) rallied in the second half to floor Fury (34-1-1, 24 KOs) and nearly stop him in Round 9 before hanging on for a split-decision victory to add the WBC and lineal titles to his WBA, WBO and IBF belts. 

Elsewhere on the card, Jai Opetaia regained the cruiserweight title he never lost in the ring against a familiar face. Opetaia battered Mairis Briedis before surviving a late onslaught to capture the IBF title at 200 pounds. The native of Australia is undefeated at 25-0 with 19 knockouts on his resume. Plus, Anthony Cacace pulled off one of the biggest upsets of the year in stopping Joe Cordina to claim the IBF super featherweight title. The 35-year-old badly hurt Cordina early in the fight as the referee was stepping in to break up a clinch and Cordina never fully recovered as Cacace poured on the pressure before the fight was waved off.
