Anthony Joshua will face Jake Paul in an eight round fight which will be broadcast live on the streaming platform.
British boxer Joshua said he will "overwhelm entirely" Jake Paul and "break" his opponent as the combatants confronted each other to build hype for next month's bout.
Ex two-time unified heavyweight champion Joshua meets social media star turned fighter Paul - in what is, theoretically, a huge uneven pairing - at Miami's Kaseya Center on 19 December.
Boxer's Mindset
"I will injure his face and damage his physique. My goal is to show I'm the better fighter," Joshua, 35, declared.
"I'll stamp all over him. That's how fighters think.
"I intend to genuinely try to cause him pain. That's my intention."
Respectful Exchange
Despite such comments, a composed Joshua and social media star Jake Paul - normally famous for his dramatics - exchanged pleasantries and remained civil with each other.
Paul rather criticized ex Joshua opponent Francis Ngannou and called him "a joke" after Ngannou declined a bout proposal.
Taking Aim at Fury
Anthony Joshua, in the meantime, targeted UK rival Tyson Fury - and declined a million-pound wager 'Tyson Fury' claims he will make on a victory for Paul.
"Jake Paul outshines Tyson Fury - he showed up," Joshua stated.
"I respect him for that."
Legitimate Opponent
Despite declaring he will hurt Jake Paul, Joshua declined to talk badly about his rival's pugilistic talent.
"Jake is a credible opponent," he said.
Jake Paul's History
Jake Paul - who first rose to fame on the television network - has mainly boxed mixed martial artists or past-their-prime fighters since entering professional boxing.
He lost to British fighter Fury in 2023.
Financial Attraction
However, the inexperienced fighter continues to be one of the sport's greatest commercial attractions, consistently making massive financial rewards.
Forecast and Belief
The 28 year old predicted a KO victory in rounds four or five and claimed he would prevent the highly-expected Fury-Joshua bout, which is allegedly under discussion for two years from now.
"The next fight will be myself against Tyson Fury in the coming year," Paul said.
Physical Difference
As the two fighters met for the usual confrontation, with their size difference on show, it highlighted just how unlikely this entire matchup is - and how amazing it is that the bout is really happening.
