Khabib Nurmagomedov defeated Conor McGregor in the fourth round of their UFC lightweight title fight, but the stunning result was immediately overshadowed by a post-fight brawl which culminated in three arrests.

Khabib immediately jumped over the Octagon after McGregor tapped out, hurtling towards the Irishman’s corner and attacking his training partner, Bellator welterweight Dillon Danis.

McGregor was meanwhile attacked by at least two members of Nurmagomedov’s team, who took advantage of the chaos by vaulting their way into the Octagon. However, footage later emerged which appeared to show McGregor throwing the first punch.

Here is everything we know so far about the situation.

Nurmagomedov fought with Danis immediately after submitting McGregor in the fourth round of their title fight. Police officers separated the two men.

McGregor climbed onto the Octagon walls and appeared to throw a punch at one of Nurmagomedov's team. He was then dragged back into the Octagon.

At least two men jumped into the ring to attack McGregor. One threw a punch at McGregor which was deflected, while another struck the Irishman in the back of the head.

Security personnel eventually separated the two entourages. Both McGregor and Nurmagomedov were given police escorts out of the T-Mobile Arena.

UFC President Dana White made the decision not to present Nurmagomedov with his belt because of security concerns.

White later said that three of Nurmagomedov’s team had been arrested and “were on their way to jail”.​

Zubaira Tukhugov, a featherweight with a 3-1 record in the UFC, was one of those involved in the attack on McGregor.

McGregor however decided not to press charges and the men were released.

White has promised that any contracted fighters who were involved in the brawl will never fight for the promotion again. Tukhugov had been due to fight McGregor's sparring partner Artem Lobov later this month.

Nurmagomedov's purse will be withheld pending an investigation by the Nevada Athletic Commission.

Nurmagomedov may also face criminal charges for his role in the brawl, potentially complicating any US visa applications he makes in the future.

However he did at least receive a congratulatory phone call from President Vladimir Putin.

White added that no decision has yet been made on whether Nurmagomedov will be stripped of his lightweight title
