“Talking’s over,” Tyson said before making his exit with members of his entourage.
Paul, the 27-year-old Youtuber-turned-boxer, insisted he had not been hurt by Tyson’s open-handed slap, which drew gasps from the audience.
“I didn’t even feel it - he’s angry. He’s an angry little elf... cute slap buddy,” said Paul, who weighed in at 227.2 pounds (103.05kg).
Paul concluded his remarks with an expletive-laden pledge to knock Tyson out, before roaring theatrically into a microphone: “He must die”.
Tyson is reportedly being paid US$20 million ($34.13m) for Friday’s officially sanctioned bout in Texas, which will be comprised of eight two-minute rounds.
The contest, being streamed live on Netflix, has divided opinion across the boxing world, with many prominent figures decrying the prospect of Tyson lacing up his gloves nearly 40 years after his professional debut and 19 years after his last officially sanctioned fight.
