Fans have recently voiced their concerns over Tyson’s carefully crafted training montages.

But The Sun reports in a newly released clip, it was Iron Mike’s sparring partner who supporters were left feeling sorry for.

In the footage, Tyson backs his sparring partner up to the ropes and unleashes a trademark left hook.

The training partner sinks to the floor against as Tyson roared: “I’ve got a lot in me. I’m just getting started.”

His trainer can be heard telling the 58-year-old as they wrapped up the session: “That was good for today. You did great, we’re done.”

In response to the footage, one fan wrote on social media: “He’s looking scary boys.”

A second said: “Imagine a world where 59 year old Mike Tyson knocks Jake Paul out. It would be beautiful.”

Another added: “When you hear Mike say I’m just getting started you better run the other way.”

It comes after Paul also released sparring footage dropping a heavyweight with an overhand right.

The already controversial clash was further scrutinised when Tyson was forced to pull out of the initial July 20 date.

He suffered an ulcer flare up in his stomach but has since been deemed medically fit to continue training.

Tyson is also required to undergo additional brain and hearts checks ahead of his fight along with pre-bout drug testing alongside Paul.

Paul, 27, has ten wins and only one loss in the boxing ring, losing a 2023 split-decision to Tommy Fury, 25.

Tyson meanwhile returns for his first pro fight since 2005 despite facing Roy Jones Jr in an exhibition bout in 2020.
