Mike Tyson will make a sensational return to the ring on Saturday when he fights fellow former heavyweight champion Roy Jones Jr.

Tyson, 54, will step through the ropes for the first time since 2006 for an eight-round exhibition bout against Jones, who is three years his junior.

Both men have had incredible boxing careers and have held multiple world titles between them - as well as amassing huge wealth.

Tyson became the youngest world heavyweight champion in boxing history when he won the WBC belt aged just 20 in 1986.

He went on to reign as undisputed world champion from 1987 to 1990, and regained the WBC and WBA titles in 1996.

Mike Tyson has earned a colossal amount during his long career

In between he was convicted of rape in 1992 and sentenced to six years in prison, of which he served three.

And he attracted controversy in 1997 when he famously bit Evander Holyfield's ear during an 11th-round stoppage defeat to his rival.

According to Forbes, Tyson earned a staggering $685million during his career, which stretched into the 21st century with a defeat to Lennox Lewis in 2002 before he hung up his gloves four years later.

That's about £513m according to the latest exchange rates - and it's a colossal amount by any measure.

However, he had his share of financial problems and filed for bankruptcy in 2003, with the BBC reporting at the time that he had squandered $300m in ring earnings.

It has been reported that as of 2020, his net worth is around $3m (£2.25m).

His bank balance is set to soar, however, with Tyson and Jones in line to pocket $10million each from Saturday's fight - that's around £7.5m.

Tyson and Jones will also split the bonus from pay-per-view sales - and according to some estimates they could both be $20m richer by the end of the night.

That's still some way short of Tyson's biggest payday - after he reportedly earned more than $30m from his 2002 defeat to Lewis.

His opponent on Saturday has held world titles at four different weights, and is the only boxer in history to be crowned heavyweight champion after starting his professional career at light middleweight

Jones' best-paying fight was against John Ruiz in 2003, when he won the WBA heavyweight title and banked a reported $26m.
