Khabib Nurmagomedov's convincing win over Conor McGregor was marred by ugly scenes outside the Octagon as a mass brawl broke out between the two fighters' teams.

Khabib forced McGregor to submit before quickly hopping over the cage to get his hands on the Irishman's team-mate Dillon Danis. Chaos ensued and now it appears that McGregor may be the man responsible for the ugly scenes.

New footage shows the Irishman tried to follow Khabib out of the cage and hit the Russian's coach with a few cheap shots.
