The rivalry between Conor McGregor and Khabib Nurmagomedov erupted into chaos on Saturday night at the T-Mobile Arena in Las Vegas.

Nurmagomedov retained his lightweight title (27–0) by forcing McGregor (21–4) to tap out at the highly anticipated UFC 229. But he then jumped out of the Octagon and a melee ensued. 

Others jumped into the Octagon and McGregor was attacked. Nurmagomedov then ended up back in the action as well. 

UFC president Dana White saying he wasn't going to put the belt on Nurmagomedov because there would be more issues. 

There were no post-fight interviews either, and security led Nurmagomedov out of the cage.
