Israel Adesanya

UFC middleweight champion Israel Adesanya has been one of the hottest properties in the sport over the past few years, appearing indestructable during a perfect 19-0 run so far.

However, ‘The Last Stylebender’ also has a vast amount of experience as a kickboxer where he racked up no less than 80 fights and won 75 of them – an impressive resume by anyone standards.

That being said, the final fight of his kickboxing career in 2017 resulted in the one and only knockout loss of his entire career.

Adesanya was fighting Alex Pereira at Glory Of Heroes 7 and it delivered some exciting action in the opening rounds, including ‘Izzy’ rocking his opponent.

As such he started the third round in confident fashion with a flying knee, but later Pereira landed cleanly with a left hand to the jaw that flattened Adesanya on the canvas for a highlight-reel KO finish.

Nevertheless, Adesanya bounced back just a few months later with a TKO victory over Melvin Guillard in an MMA fight and within a year was signed by the UFC.
