A coin toss has decided one of the three judges for tonight’s rematch between Oleksandr Usyk and Tyson Fury, just hours before the pair are due to lace up the gloves for their big heavyweight title fight.

Puerto Rico’s Gerardo Martinez, Chicago’s Patrick Morley and Miami’s Fernando Barbosa were originally selected as judges to score Usyk vs. Fury 2.

But Barbosa reportedly fell ill during fight week and was unable to make the trip to Riyadh, Saudi Arabia, where Usyk and Fury will face each other for the WBA, WBC and WBO titles.

Due to Barbosa’s withdrawal, Panama’s Ignacio Robles and New Jersey’s Steve Weisfeld were flown in as possible replacements. Weisfeld was believed to have gotten the gig, but a coin toss early Saturday afternoon determined Robles will be Usyk-Fury’s third judge tonight.

Barbosa’s appointment to the board was initially controversial. The American judge also serves as a broadcaster for ESPN KnockOut and as senior vice president for Disney Latin America – Disney is the parent company of ESPN. Although ESPN will not broadcast the rematch, it has an exclusive content agreement with Bob Arum’s Top Rank Inc., which is co-promoting Fury with Frank Warren’s Queensberry Promotions.

Not only does he comment on what’s happening at the ring, but he is also more directly involved in some boxing events. Barbosa is responsible for acquiring licensing rights for games broadcast throughout Latin America. That job involves regularly negotiating with broadcasters to secure TV rights deals, which is a worrisome business relationship for a judge.

Keith Idec of Uncrowned was the first to break the news.

Usyk (22-0, 14 KOs) defends his WBA, WBC and WBO titles against Fury (34-1-1, 24 KOs) tonight at the Kingdom Arena in Riyadh, Saudi Arabia.

Usyk defeated Fury by a split decision to win the undisputed heavyweight title in May. The Ukrainian became the first fighter to hold all four heavyweight belts, becoming undisputed champion in two divisions.
