British boxing legend Anthony Joshua has had some memorable fights over his incredible career.
The former heavyweight champion has taken on some of the very best, including being victorious in an epic clash with Wladimir Klitschko.
Despite losses to Daniel Dubois and Oleksandr Usyk, Joshua will be remembered fondly in boxing for a long time to come, thanks to his contribution to the sport.
However, one of the most memorable moments of his career was a back-and-forth round against an unlikely challenger.
Anthony Joshua faced an unlikely opponent on short notice in 2019
In June 2019, Joshua was set to defend his IBF, IBO, WBO, and WBA (Super) World Heavyweight titles versus Jarrell Miller in New York.
However, following failed drug tests from heavyweight contender Miller, the then 23-0-1 fighter was ineligible to compete.
A short-notice replacement was found for the champion, as Andy Ruiz Jr. stepped up to the plate.
According to a report from Sky Sports, Ruiz Jr. was supposed to help Joshua prepare for Miller in sparring. However, as Miller withdrew, the Mexican wanted to be considered for the title opportunity.
Despite being a huge underdog, Ruiz Jr. was given the chance at the heavyweight titles, going into the bout with a record of 32-1.
The Mexican would prove bookmakers wrong, however, as he had an incredible performance.
Anthony Joshua vs Andy Ruiz Jr. produced one of the greatest rounds of all time
Many believed that Joshua would have a convincing and dominant performance over Ruiz Jr. However, that was not the case.
Although there were no major talking points from the opening two rounds, the third round would be completely different.
It appeared as if the favorite was about to have the showing that people expected. In the opening minute of the round, the defending champion would put the challenger down.
However, things would very quickly change after the knockdown. Ruiz Jr. would respond phenomenally, scoring his own shock knockdown over Joshua, as the champion was seeking the finish.
As both men were still recovering, they were also looking to land a significant blow on one another, as tensions rose throughout Madison Square Garden.
In the closing seconds of the round, the Mexican would throw a barrage of punches to his wounded opponent, before Joshua would crumble to the canvas for the second time just before the bell rang.
Getting back to his feet to beat the count, Joshua was able to continue the fight, however, the champion looked dazed after the shocking round.
Despite being on the verge of a stoppage loss in the third round, Joshua would survive, however, only until the seventh round.
Joshua would go down for a third time in the opening minute of the seventh round, then down for a fourth-time seconds later. Although Joshua returned to his feet, the referee waved off the bout, making Ruiz Jr. the champion.
However, Joshua would get his revenge on the fighter to give him the first loss of his career. Fighting in a newly built arena in Saudi Arabia, Joshua would win the fight via unanimous decision six months later.
