Floyd Mayweather believes that the fight with Mike Tyson will now land before the end of the year.50-0 retired legend Mayweather and heavyweight icon Tyson announced they would fight in a bizarre exhibition clash.The bizarre bout appears to be back on despite multiple obstacles legally outside of the ringGetty/talkSPORTThe organisers CSI initially plotted for the pair to meet in spring last year, but a hand injury for Tyson delayed the contest.A plan to reschedule the contest was made, but Mayweather had signed up to face Greek kickboxer Mike Zambidis.CSI had also paid Mayweather an advance of $4.75 million as part of a two-fight deal which included a lucrative sequel with Manny Pacquiao.But a contract dispute broke out and the bouts all collapsed, with legal battles unfolding behind closed doors.Plans were then put in place for the bout to fight in September, but again the date passed by and the clash never did take place due to outside of the ring issues.However it appears a breakthrough has now been made.During a recent interview, he said: “December we got Mayweather-Mike Tyson exhibition, that’s definitely going to be in December. “And I think Pacquiao-Mayweather will be somewhere in 2027.”Mayweather now appears closer than ever to finally returning at the age of 49.His bout with Tyson will not land on his professional record, given the pair are far beyond their careers and are a gulf apart in terms of weight.Mayweather and Tyson are polar opposites, but they could clash under exhibition rulesGetty/talkSPORTWhy is Mayweather vs Tyson happening?Tyson and Mayweather have both continued fighting well beyond their physical primes.The pair have identified that they can still generate lucrative purses and big commercial events, despite ageing and dropping off in levels of skill.‘Money’ is one of boxing’s greats, but has stooped down to lower level opposition including Logan Paul and Deji in social media exhibition bouts.Meanwhile for Tyson, at the age of 60, his health is declining but he still fought in a blockbuster bout with Jake Paul.The event drew record global viewership on streaming service Netflix, and organisers will hope the two pay-per-view draws can carry the same success.Given the turbulent build-up, it still remains unclear if the bout does indeed materialise.Watch Boxing on DAZN*If you click a link in this boxout, we will earn affiliate revenueSign up to DAZN to access the definitive subscription for boxing fans.Upgrade to DAZN Ultimate from just £24.99/month, guaranteeing access to 185+ fights annually, a minimum of 12 pay-per-views at no extra cost, as well as every Lega Serie A match and other elite football access.Alternatively, DAZN Standard is just £15.99/month, with the caveat you will have to pay for pay-per-view events.Click here to sign up.But both American superstars have declared they are signed and ready to go.
