MIKE TYSON looks a lean, mean knockout machine ahead of his comeback fight against Roy Jones Jr.

But Iron Mike’s opponent for their November 28 blockbuster is looking no slouch himself, as his rapid training video shows.

There is just over a month to go until Tyson, 54, and Jones Jr, 51, get it on at Dignity Health Sports Park in California.

And both men look in simply incredible shape considering they have a combined age of 105.

Tyson, while not as bulked up as his prime heavyweight days, is the envy of men 30 years younger than him with an eye-catching six pack.

And while ex-middleweight and heavyweight king Jones Jr – who admits he could die in the fight – kept his top on for training, the amount of work he put in was evident in his sweat-soaked T-shirt.

Tyson wrote alongside his latest sparring clip: “What do you have to be in order to be brave? You have to be afraid to be brave.

“That’s what makes people say you’re brave, because they know you’re afraid.

“And now you’re facing something that’s unnatural to be facing, but you control your fear and you face it.”

Jones Jr – who is set to retire for good after the fight – spared fans the psychobabble in his latest video.

But he left them equally flummoxed by his ability to be so fast even in his advancing years.

One user labelled him ‘superhuman’.

Another said: “It’s crazy to think that Roy Jones Jr was even faster than this. That’s insane!”

A fellow user wrote: “Freaking handspeed still legit.”

But one warned: “Fast hands mean nothing, he looks like he can’t move.”

It was Tyson who fans were worried about though after his bizarre interview with Piers Morgan on Good Morning Britain.

Slurring his words and dropping his head, Tyson could barely get his words out.

However, he later confirmed his groggy performance was down to the fact he had just woken up.
