Mike Tyson is confident that Andy Ruiz Jr. will once again win against the former unbeaten champ, Anthony Joshua in their upcoming rematch later this year.

On June, Ruiz Jr. shocked the boxing world by beating the highly favored Joshua on a seventh-round TKO. Boxing pundits have dubbed the match as one of the biggest upsets in the history of the sport.

To redeem himself, the British pugilist immediately activated a rematch clause to avenge his first loss. However former heavyweight "Iron" Mike Tyson believes that Ruiz will once again dominate AJ.

Earlier this month, the former undisputed heavyweight king met the Mexican-American boxer to record a podcast. Tyson told ESPN that "he was here the other day."

Mike also shared that Ruiz was "really a beautiful person," adding that "if he did it once, he could do it again. We'll have to find out."

Ruiz, Joshua 2 is one of this year's most anticipated matchups. Anthony will be looking to avenge his loss; he even confidently said that he would "beat Ruiz's ass in Mexico."

Ruiz angrily responded and refuted. He said that if AJ "can whoop me in Tijuana prove it let's run it in Mexico." He continued and stated that "remember that you did have a huge reason to come to America... to build your profile. #Ruiz2 #cherrypickgonewrong."

The venue for their upcoming rematch is still undecided, with AJ later conceding that he prefers to fight on "neutral grounds." Their fight is rumored to be slated in December.

Ruiz has been gaining notoriety after handing AJ his first loss. The pudgy heavyweight champion was often underestimated in his boxing career due to his frame.

In a recent interview, the first Mexican-American heavyweight champion sad that he used to fight 12-year-old amateur boxers when he was still 7-years-old. He noted that no one was as big as he was so he had to fight older fighters in his amateur days.
