Tyson Fury weighed in nearly two stone lighter than Mariusz Wach for Friday's heavyweight fight in Thailand.
Fury clocked in at 265lbs, two pounds lighter than he was when he faced Arslanbek Makhmudov in April.
But in a remarkable reversal of roles, Fury was dwarfed by Wach who tipped the scales at 291.4lbs, 26.4 pounds heavier.

"Yes [I've put in the work], this is my second camp back-to-back after a 16-month lay-off. I'm getting sharper, fitter, and stronger every day," Fury said at the weigh-in in Pattaya.
"I've never faced a man heavier than me. I'm very happy to be fighting. I'm not banking on any fight happening or not happening. I'm a fighter, I want to keep busy. I've had one fight in over two years.
"I want to box his head off for 12 rounds, if possible. I'm there to box and move, use my attributes. I've got to be 100 per cent focused, switched on, take nobody as an easy touch and do my job, like I always do."
The 37-year-old is gearing up for his 39th career fight and will take on Poland's Wach in front of just 1,500 fans at the Max Muay Thai Stadium in Pattaya which could be a warm-up for a much-anticipated bout with Anthony Joshua.
Joshua is also in action this weekend as he takes on Kristian Prenga in Saudi Arabia for his first fight since beating Jake Paul in December 2025.
Fury's fight on Friday will not be broadcast live but will be shown as part of his Netflix documentary series, 'At Home with the Furys'.
