Anthony Joshua vs Andy Ruiz Jr 2: How heavyweight greats including Mike Tyson have done in first fight since shock defeats By Jackson Cole

Following his shock defeat to Andy Ruiz Jr in June, Anthony Joshua is about to get his long-awaited shot at redemption.

Joshua lost his WBA, IBF and WBO heavyweight belts when he was stopped by the Mexican-American in New York, one of the biggest shocks in boxing history.

But on Saturday night, AJ can put things right when he and Ruiz do their rematch in Saudi Arabia.

This fight is an intriguing prospect because it will give fans an idea of what the Brit is truly made of having suffered such a setback last time out.

He still has the opportunity to become one of the greats in the heavyweight division but must win this fight.

There have been some shocks similar to this in the past and shortly after AJ's defeat to Ruiz, we took a look at some the greatest upsets in heavyweight boxing.

Michael Moorer after George Foreman def. - 1994

Following his shock defeat to a 45-year-old Foreman in Las Vegas, Moorer was back in action a year later.

He faced fellow American Melvin Foster in Sacramento and got the job done, winning by unanimous decision.

Moorer reclaimed his IBF heavyweight crown when he beat Axel Schultz in June 1996 after winning by split decision but lost his belt when in a unification match with WBO champ Evander Holyfield.

Sonny Liston after Cassius Clay def. - 1964

The pair were due to have a rematch in November 1964 but had to be delayed when Clay [who then became Muhammad Ali] needed emergency surgery for a strangulated hernia.

But the rematch was rearranged for May 1965 and much like the first bout, Ali won by knockout, flooring Liston in the first round.

The result was controversial however, with suggestions Ali's punch that sent Liston to the canvas did not actually connect with him and was since labelled the 'Phantom Punch'.

Mike Tyson after Evander Holyfield def. - 1996

Iron Mike suffered a surprise defeat to the 25/1 outsider Holyfield in November 1996 but the pair fought a rematch in June the following year.

And this bout gave a real insight into Tyson's madness as he was disqualified for biting Holyfield on both ears in the third round.

He lost his boxing license for the incident and did not fight again until 1999.

Lennox Lewis after Hasim Rahman def. - 2001

Like Joshua, Lewis was guilty of looking ahead to the big fight in the future before suffering a defeat to an opponent they weren't expected to lose.

But Lewis fought his conqueror in November 2001 and made no mistake second time round, winning via knockout.

The British fighter did then get his big fight with Tyson in June 2002, winning that by knockout too.

Mike Tyson after 'Buster' Douglas def. - 1990

He's viewed by many as the best heavyweight boxer of all time but Tyson actually suffered six defeats in his professional career.

Tyson's first defeat was the most shocking though and was probably more of an upset than Joshua's defeat to Ruiz.

There was no rematch though, instead, Tyson fought Henry Tillman next and won that by knockout.

With the exception of Tyson's rematch against Holyfield, AJ will be looking for a similar response to this in the Middle East.
