Anthony Joshua will face Jake Paul in an eight round match which will be shown live on the streaming platform.
Briton Anthony Joshua said he will "stamp all over" the American and "break" the American as the combatants met personally to promote the upcoming heavyweight fight.
Former two time world title holder Joshua meets social media star turned fighter Paul - in what is, by the numbers, a massive uneven pairing - at Miami's arena on 19 December.
"I'm going to damage his features and hurt his body. I'm here to prove I'm superior," Joshua, 35, stated.
"I will dominate him completely. That's how fighters think.
"I will genuinely try to injure him. That's my intention."
Despite such comments, a composed Joshua and social media star Paul - normally famous for his theatrics - exchanged pleasantries and maintained decorum with each other.
Paul rather criticized former Joshua opponent Francis Ngannou and described him as "ridiculous" after Ngannou turned down a fight offer.
Anthony Joshua, meanwhile, took aim at British rival Fury - and rejected a £1m bet 'The Gypsy King' claims he will make on a Paul victory.
"[Paul] is superior to Tyson Fury - he showed up," Joshua stated.
"I give him credit for that."
Despite declaring he will damage his opponent, Joshua declined to talk badly about his rival's fighting skills.
"Jake is a credible opponent," he stated.
Paul - who initially became famous on the television network - has mostly boxed mixed martial artists or past-their-prime fighters since turning professional.
He was defeated by Briton Fury in last year.
However, the inexperienced fighter is still one of the sport's greatest money-making draws, consistently making substantial financial rewards.
The 28 year old forecast a knockout win in round four or five and claimed he would prevent the highly-expected Fury-Joshua bout, which is allegedly being planned for two years from now.
"It will be myself against Tyson Fury in the coming year," Jake Paul said.
As the two fighters engaged in the customary face-off, with their height and weight contrast on show, it drove home just how improbable this whole event is - and how astonishing it is that the bout is actually proceeding.
