Jake Paul provides Mike Tyson update after boxing icon's health scare as Eddie Hearn rages

While Tyson has also insisted he's feeling good, there remain concerns over what could happen when he returns to the ring on November 15.

At the age of 58, Iron Mike will be the underdog - with Paul currently 31 years his junior at the age of 27.

Paul, speaking to TMZ, has insisted Tyson is 'super healthy'. He also revealed there's no back-up in place, too.

"I don't have concern," said 'The Problem Child'.

"He's doing great. He's super healthy behind the scenes and feeling great.

"So that's what we are focusing on and there is not a back-up currently."

The fight is arguably one of the most controversial in the sport's entire history.

Tyson was one of the best heavyweights of his generation during his prime years, winning 44 of his 50 professional bouts via knockout.

Yet there are plenty of figures unhappy at the clash going ahead.

Among them is boxing promoter Eddie Hearn, who has questioned 'what on earth' the pair are doing.

“I'm lucky enough to have a business where we don't need to do that.

"And I will never do that.

“Anyone that thinks that [Tyson] should be in the ring right now either doesn't have his best interests at heart or is an idiot.
