Tyson Fury weighed in at three stone heavier than Deontay Wilder for their WBC world heavyweight title clash in Los Angeles on Saturday.
After a heated press conference on Wednesday, both men were kept apart and did not engage in a face-to-face after weighing for Saturday's title fight.
Fury tipped the scales at 18st 4lbs while defending WBC champion Wilder came in at his lightest since making his debut a decade ago as he weighed 15st 2lbs.
Both unbeaten en were then kept at opposite ends of the stage for a final look at each other before the fight - where Gypsy King Fury tried to get at Wilder by shouting and gesturing at the American.
Wilder, though, did not flinch as he stood wearing a mask on his face throughout the weigh-in and even in interviews just afterwards.
The 33-year-old said: "(This is) definitely the most important but definitely not the most difficult. I (have) fought way tougher guys than him.
"My opponent last fight (Luis Ortiz) was way tougher than him. This is just another step to get to where I want to go - there will be one champion (in the heavyweight division), one face, one name, and he'll go by the name (of) Deontay Wilder.
"I get to release everything that's inside of me. I can't wait. I'm going to knock him out."

Saturday's fight will take place in a 20ft ring - four foot smaller than the maximum permitted size, which the 30-year-old Fury used to memorably defeat Wladimir Klitschko - favouring the aggressive American.
Earlier, Wilder had said: "If people didn't think I hold all the marbles in boxing, after this fight, there ain't going to be any question who holds the marbles.
"The promotion has been amazing and I thank God for Tyson Fury because I have had to promote all of my old opponents. They were too scared to say what they would do.
"This event is big for me, all the guys before brought something to the table to take me to the next level.
"A lot of people doubted me before I fought a certain calibre of fighter. Ortiz changed that and Fury will do the same for me. I want you to witness greatness."
Wilder may not be the polished champion the Klitschko was when Fury unexpectedly outpointed him three years ago this week, but he is widely considered a more powerful and more explosive puncher.
The 30-year-old Fury recognises the extraordinary power that he possesses, but he also insists that Wilder is so flawed that he should still pose little threat.
"He punches hard but he didn't fight anyone until he'd had 30 fights," he said. "You can only knock out who's in front of you but if you're matched easily you get to 100-0.
"People are afraid before they get in there, like with Mike Tyson. They were just looking for a comfy place on the canvas.
"If I can't beat Deontay Wilder then I'm not very good, simple as that. If I can't beat Wilder I'm not the man I think I am. If I win a close fight I'll class it as a loss because it's not enough for me.
"How are you going to be considered a great if you can't beat a bum who throws windmills?"
There has also been little in the final days to change the widely-held view that the likeliest outcomes are a Wilder stoppage victory or a negative Fury earning a decision, but the latter's promoter Frank Warren said: "I don't think this will be a dancing contest. To fight (Wilder), you have to put him on the back foot.
"You have to take him out of his comfort zone. Let's see how he likes it if he starts putting it on him."
