Conor Benn and Ryan Garcia both comfortably made the welterweight limit for their WBC title fight, despite concerns at how they would fare on the scales.
Briton Benn, 29, weighed in at 10st 6lb (66kg) for Saturday’s bout – half a pound heavier than the champion.
The official weigh-in took place behind closed doors at the UFC Apex on Friday, in front of about 50 members of the media.
Speaking at a ceremonial event in front of fans later in the day, Benn already looked noticeably bigger, his face and shoulders having filled out.
“Did it look hard? How did I look?,” he asked. “We’ll see tomorrow night how good I really feel.”
Benn has previously said he could weigh as much as 12st 7lb (80kg) by the time he steps into the ring on Saturday.
Garcia has won 25 of his 28 professional contests, including 20 knockout victories, with two defeats and one no-contest. Benn has 25 wins – 14 by knockout – and one loss, and is fighting for his first world title.
American Garcia, 28, won the WBC belt with a dominant points victory over Mario Barrios in February and is making his first defence against Benn.
