Khabib Nurmagomedov won his UFC lightweight title defence against Conor McGregor but ended the fight by jumping over the octagon to attack McGregor's jiu jitsu coach.
Conor McGregor and Khabib Nurmagomedov's rivalry really heated up when the Irishman turned up ahead of the Russian's previous fight, the title fight with Al Iaquinta, and throwing a trolley at the bus the Eagle was on.
Finally the two men got it on in the octagon on Saturday night at UFC 229 in what became an instant classic with the Russian winning with a fourth round submission, a reverse neck crank/choke hold.
However the action wasn't over as the undefeated Russian jumped outside the cage to attack the Irishman's jiu jitsu coach. As things started getting crazy a member of the Russian's camp got into the octagon and threw some big punches at the recovering McGregor:
After the attack Khabib returned to the ring with his entourage and security kept the two men apart but the final proceedings couldn't happen.
The winner was not given the belt by Dana White. The UFC president explained that he feared for the reaction of the crowd saying, 'more people could get hurt' and instead ushered the champion out of the octagon.
Bruce Buffer then announced Khabib as the winner by submission without the winner even in the octagon.
The whole rivalry had been personal from the moment that Khabib had approached Artem Lobov, which led to McGregor's confrontation with the bus.
All of that continued in the pre fight build up with the former lightweight and featherweight champions taking shots at Khabib for his political allegiance and at the Russian's manager for his past.
It was a brilliant fight after all the shenanigans with the Russian showing everything in his power to put on an excellent performance and take the biggest win of his career.
However after all that the fight will only be remembered for one thing.
