Now 60 years of age, McCall shocked the world last year when he had his first fight in five years when he defeated Stacy Frazier in Tennessee. 

Since then, McCall has had two more fights as he struggles to say goodbye to a sport that saw him reign as heavyweight champion in the mid-1990s after he sensationally stopped Lennox Lewis. 

McCall would lose the crown to Frank Bruno in 1995 before succumbing to Lewis in a rematch two years later. 

A veteran of 78 fights, McCall holds the honour of never being dropped in his career, a remarkable feat considering he operates at heavyweight and has faced huge punchers such as Lewis and Larry Holmes. 

With his professional run starting in 1985, McCall has been around 40 years, but in all that time, who does he believe carried the most power in the heavyweight division? 

After two memorable battles, with Lewis, McCall credits the legendary fighter as being the hardest hitter he ever faced. 

“I’d pick Lennox. I’m just going off what went through my mind,” said McCall when speaking with The Ring .  

“Bruno hit me dead in the eye, but it wasn’t as brutal as far as the shock to my body or pain as that right hand was.

"When Lennox hit me with that right hand in the third round, that was a crunching right hand.

"It makes me think I don’t know how I could take the punches that came after it with my hands down.”
