Saturday night's main event will ultimately be a bout between Evander Holyfield and Vitor Belfort. The same tournament will feature fights between Anderson Silva and Tito Ortiz and David Haye and Joe Fournier, among others.
Holyfield replaced Oscar De La Hoya, who was hospitalized after contracting a coronavirus, in the main bout. The former heavyweight and featherweight champion was previously set to fight Kevin McBride.
Ultimately, all bouts will be official, but most will follow an eight 2-minute round format. In the U.S., the evening will be shown on pay-per-view for $50.
