Anthony Joshua will defend his WBA and IBF heavyweight titles against Carlos Takam in Cardiff on Saturday night and is fully expected to win fairly comfortably.
Around 78,000 will be inside Cardiff’s Principality Stadium to watch Joshua take on Takam - who replaced the injured Kubrat Pulev at late notice.
Friday saw the weigh-in and Joshua’s weight got everyone talking.
The Brit tipped the scales at 18 stone two pounds - four pounds heavier than his previous fight against Wladimir Klitschko.
It’s the heaviest Joshua has ever been during his career as he looks to extend his record to 20-0.
Why Joshua weighs heavier
But why does he weigh more than he ever has before?
"I've been doing a lot more running, I'm filling out as I get older,” he admitted.
Joshua won't be complacent
But there is simply no way Joshua will underestimate his opponent.
"I think too much confidence can become cocky,” Joshua added.
"I've got to keep a cool head on my shoulders. I didn't expect a turnout like this, I appreciate it.
"I think he's got a mindset of nothing to lose. He came in and grabbed my hand to see who's got the stronger hand shake. It's a dangerous mindset.
"I have to find a way to break him down, round by round. #StayHungry. I'm hungry still, for ever and ever. Everybody is hungry to succeed at whatever they are doing.
"You can be on the defensive but conserving energy. With Wladimir it was intense. Knowing my position in the ring. Being comfortable even when I'm not attacking."
Big night for British boxing
With it set to be a world record indoor crowd - beating the previous record set by Muhammad Ali in 1978 when 63,315 fans saw him beat Leon Spinks in the New Orleans Superdome - Joshua’s promoter Eddie Hearn knows what a special occasion it will be.
"We’ve never seen anything like this in British boxing and we may never see anything like it again,” Hearn said.
"This fight will be broadcast in over 160 countries worldwide."
