The biggest fight in UFC history, a moment between former champion Conor Mc Gregor and defending champion Khabib Normagodev, a fight that has been gathering so much tension and attacks under the scene for a while, ended with a post match brawl leaving both sides injured, after Khabib Normagodev knocked out his compatriot Conor Mc Gregor.

A man – appearing to be one of Khabib’s team-mates – hopped into the octagon and aimed a punch at McGregor from behind.

Nurmagomedov responded to a taunt from the crowd by McGregor’s teammate Dillon Danis by jumping outside of the Octagon and beginning to throw punches.

Fans were left stunned as a mass brawl broke out beside the cage and McGregor was ashen-faced as he was escorted out of the arena by security.

UFC President Dana White revealed that three of Khabib’s team-mates had been arrested but were released as McGregor refused to press charges against them.

White said at the post-fight press conference: “Conor was one of the guys who was attacked and things like that and Conor refused to press charges.

“The guys that they did have were released. There were three guys that I think were from Khabib’s team that were arrested and they were released because Conor didn’t want to press charges.

The undefeated champion Khabib apologised for climbing over the cage but slated McGregor for his personal insults in the build up to the fight.

He was quoted as saying “I want to say sorry to the Nevada Athletic commission, sorry to Vegas, I know this is not my best side.

It was confirmed that Mc Gregor insulted his religion his family which led to the reaction.
