Usman Nurmagomedov, Khabib's second cousin, beat the Georgian fighter Merav Devlishvili in Abu Dhabi.
The footage shows how several people approached Devalishvili, slapped him in the face, and then a fight broke out.
We arrived in Abu Dhabi, and Osman and his friends crept up behind us like snakes. And you call yourselves warriors? Is this male behavior?
If you want to talk or fight, let's be honest.
You are just little cowards. We bleed and fight, and you are the vile types.
You are not men: it shows your character and what kind of people you are.
Under UAE law, Nurmagomedov's brother and other attackers could face life imprisonment.
