JEDDAH, Saudi Arabia (AFP) — British boxer Anthony Joshua weighed in more than 10 kilos (22 pounds) heavier than defending champion Oleksandr Usyk on Friday ahead of their world title rematch in Saudi Arabia.

Two-time heavyweight champion Joshua tipped the scales at 110.9 kilos (244.5 pounds) while Ukraine's Usyk weighed 100.5 kilos (221.6 pounds), both similar to last year's fight in London.

Usyk, 19-0 and the bookies' favorite after his unanimous decision on Joshua's home turf, confounded predictions that he had packed on several kilos of muscle to counter the towering Joshua.

The fighters came face-to-face in a 90-second staredown before shaking hands and posing for the cameras.

"All this stuff, weight, face-off, it doesn't matter to me. It's all about the fight," Joshua said. "I'm just ready for 12 rounds, 100 percent. Anything shorter than that, it's a bonus."

Many commentators have written off Joshua after a hesitant showing against the quick and skillful Usyk at London's Tottenham Hotspur Stadium last September.

But the 6ft 6ins (1.98m) Watford man, who is striving to become a three-time world champion, has promised to be more "competitive."

Promoter Eddie Hearn has suggested Joshua will go for the knockout.

Saturday's clash will be the 12th consecutive world title fight for Joshua, the 24-2 former Olympic gold-medallist whose other professional defeat was a shock TKO by Andy Ruiz Jr. in June 2019.

Joshua avenged that loss six months later in the "Clash of the Dunes" in Diriyah, Saudi Arabia, the first heavyweight world title fight in the conservative kingdom.

On Saturday's undercard, Somali-born Briton Ramla Ali will fight the Dominican Republic's Crystal Garcia Nova in the first women's professional boxing match in Saudi Arabia.
