BEING punched by Mike Tyson is like being hit by a grand piano, according to a top doctor.
The 54-year-old will come out of retirement to face Roy Jones Jr in an exhibition bout on November 28.
Former heavyweight world champion Tyson looks incredible shape ahead of his return to the ring after losing 100lbs.
The American called time on his career in 2005 with an impressive record of 50-6 including 44 knockouts.
A top doctor, who has a PhD in High Sports Performance, has revealed what it is like to be hit by the powerhouse.
Irineu Loturco claimed Tyson can hit his opponent in the head with an impact equivalent to 450kg – which is the weight of a grand piano.
As cited by Globoesporte, he said: “A punch from a heavyweight boxer can hit the rival in the head with an impact equivalent to 450 kilos.
“It is worth saying that this is an average value within the published studies.
“Mike Tyson has always been well above that.”
A neurologist has also revealed the risk that Tyson and Jones Jr – with a combined age of 105 – are taking by making a comeback.
Renato Anginnah warned: “Our brain ages naturally and is more likely to suffer serious injuries.
“Assimilating a blow at 54 is different from receiving a blow at 20. It is much more serious. And that, of course, involves a greater risk.”
As things stand in the current heavyweight division, Deontay Wilder is claimed to be the most powerful puncher of the lot.
But Tyson, 54, looked back to his best as he showed off his power on an aqua bag during a brutal training session.
He has insisted he feels ‘better than ever physically and mentally’ after 15 years of retirement.
The former Baddest Man on the Planet is at his lowest weight since the age of 18 when he made his debut at 15st 2lbs.
Jones Jr, 51, has shockingly admitted ‘death is a possibility’ when he squares off against Tyson.
Tyson’s trainer Rafael Cordeiro has insisted that Tyson could ‘kill somebody’ – even at the age of 54.
