Hear from #johnfury & #tommyfury at the #furyusyk open workout! The undisputed heavyweight showdown between WBC/lineal champion Tyson Fury and WBO/IBF/WBA ruler Oleksandr Usyk — Saturday, May 18, at Kingdom Arena in Riyadh, Saudi Arabia — will stream LIVE on Top Rank on ESPN+ PPV starting at 12 p.m. ET/9 a.m. PT. Fury-Usyk is the most significant heavyweight battle of the millennium, as the winner will become the division’s first undisputed champion since Lennox Lewis claimed the throne in 1999. Fury (34-0-1, 24 KOs) returns following last October’s closer-than-expected decision over former UFC king Francis Ngannou in Riyadh. He has held the lineal title since upsetting Wladimir Klitschko via unanimous decision in November 2015. Usyk (21-0, 14 KOs), an Olympic gold medalist from Ukraine, hopes to become the second man, following Evander Holyfield, to achieve undisputed status at both cruiserweight and heavyweight. The Top Rank on ESPN+ PPV is also scheduled to feature: Lineal/Ring
