After a chaotic end to what was described as the biggest clash in UFC history, Conor McGregor has reportedly refused to press charges against Khabib Nurmagomedov and his entourage, the Daily Express report.

The pair faced off inside the Octagon for four dramatic rounds in Las Vegas, before Nurmagomedov managed to end the contest via submission.

The bad blood between Nurmagomedov and McGregor didn’t end after the fight, with the Russian jumping the Octagon and into the crowd to attack the Irishman’s team-mate, Dillon Dannis.

A mass brawl sparked outside the ring following Nurmagomedov’s actions, with two of the Russian’s team-mates then hopping inside the Octagon to jump McGregor and attack him from behind.

All three could well face criminal charges, however, McGregor is said to have declined to press charges, meaning the three men could be released.

Talking after the fight, UFC president Dana White couldn’t hide his frustration as to how UFC 229 finished, claiming it will have a negative impact on the company.

This is a sporting event, if you think you’re going to start a fight once that’s over it becomes a criminal investigation.

It’s bad for the brand, it’s bad for the sport, it’s bad for both fight camps.

I don’t know how anyone can come out looking good from this.

I’m so disappointed man. I’m one of the guys who has worked 18 years to get this sport where it is today.

The thing was trending to be number 1 or 2 of all time on PPV and this is how it ends?

The company have also confirmed that lightweight champion Nurmagomedov’s fight purse has been withheld as they investigate the issue, with McGregor already receiving his fight fee.
