Evander Holyfield was involved in one of the most famous fights in boxing history.

In 1996, Holyfield pulled off a big upset when he stopped Mike Tyson in the eleventh round to capture the heavyweight title.

Their 1997 rematch generated headlines for decades to come, after Tyson was disqualified in the third round after biting off a piece of Holyfield's ear.

Many years later, the two fighters have become good friends.

Although he lost a piece of his ear, Holyfield is actually glad that Tyson bit him.

"It don’t bother me. It cost me a lot of grief but I’m glad it happened because it gave me an opportunity to talk about what forgiveness is. If somebody breaks into your house you don’t think, 'How can I break into theirs?' What people don’t know is Mike is a lot more knowledgeable than they think. They think he is crazy, but he’s a businessperson now. You can’t be the same way when you get older," Holyfield told The Times.

Holyfield, 57-years-old, is now in training with the motivation to fight again in the near future.

And Tyson, 53-years-old, is also in training for a potential ring return - in an exhibition fight to raise money for charity.

Obviously Holyfield believes a trilogy with Tyson would be the biggest charity fight to make.

He's not worried about the potential for a tear-up in an exhibition fight.

"We have a different mindset, but I don’t have to trust Mike when it comes to boxing. Why? I can box. I wouldn’t get in there with nobody if I wasn’t in shape.’ Holyfield said.

"Look, we are going three rounds. It’s not ten or fifteen. Maybe there’ll be headgear. My intention is not to knock someone out, but you’ve got 16oz gloves and you get good shots in sparring too. I look after myself. I’m OK with head shots. You better believe that if he goes at my head I’m going at his. I’m going to be shooting at his head anyway with jabs. The difference is if I hurt him I’m not going to rush in and try and get him out of there. I’ll pull back. This is a way for me to talk to young people."
