Jan Blachowicz became the first man to defeat Israel Adesanya at UFC 259 light heavyweight contest in Las Vegas.
All three judges gave the contest to the Polish fighter after dominating the majority of the rounds as it went the distance.
Israel is now 21-1 as his quest to become a two-division champion came crashing after he faced a much heavier and experienced Blachowicz.
The first round was strictly a kick-boxing match as both fighters sized each other up with a few leg kicks with none of the punches connecting.
There was much aggression from either side in the second round as Balachowicz threw body shots while Adesanya worked more on the leg kicks, but no significant damage was done at each end.
The fight took a different dimension in the third as Blachowicz tried to Adesanya on the mat but the Last Style Bender expertly broke loose from the hold. But there were many punches exchanged in the process.
The Polish Power finally got the Adesanya on his back in the championship round as the Polish fighter was in control using his body weight as an advantage in winning the fourth round.
Izzy started the last round on a promising note with several leg kicks and jabs but midway to the end he was taken down by Blachowicz.
