A fully clothed Tyson Fury was nearly 10 pounds heavier Friday night than he was when the unbeaten WBC heavyweight champion weighed in for his last fight.

The 6-foot-9 Fury stepped on the scale at 277.7 pounds for his 10-round, non-title fight against Francis Ngannou on Saturday night at Kingdom Arena in Riyadh, Saudi Arabia. The 6-foot-4 Ngannou came in at 272.1 pounds, 7.1 pounds more than he was allowed to weigh for his UFC bouts.

Fury (33-0-1, 24 KOs) officially weighed 268¾ pounds for his last fight, a 10th-round stoppage of England’s Dereck Chisora (34-13, 23 KOs) last December 3 at Tottenham Hotspur Stadium in London.

Fury, of Morecambe, England, is a 20-1 favorite, according to FanDuel sportsbook. Ngannou, a native of Cameroon who is 17-3 (12 KOs) as a mixed martial artist, will make his professional boxing debut.

The pay-per-view bout between Fury, 35, and Ngannou, 37, will not count on their records.

If Fury wins and escapes unscathed Saturday night, his 12-round title unification fight with Oleksandr Usyk will likely be announced in the ring for December 23 at Kingdom Arena in Riyadh. Ukraine’s Usyk (21-0, 14 KOs) will be ringside for Fury-Ngannou.

The winner between Fury and Usyk, who owns the IBF, IBO, WBA and WBO titles, will be crowned the first fully unified heavyweight champion of the four-belt era.

The official weights for the four heavyweight fights on the pay-per-view portion of the Fury-Ngannou undercard and one non-televised contest are listed below.
