It's unclear what instigated the altercation between Usman, Abdelaziz and the crowd.

Abdelaziz has been involved in multiple scuffles during and after mixed martial arts shows. He joined an altercation between Khabib Nurmagomedov and Nick and Nate Diaz at a World Series of Fighting event in 2015.

Usman currently fights for the UFC. The 31-year-old has a 13-1 career record as a welterweight, including a perfect 8-0 mark in the UFC. His last fight was a unanimous-decision win over Demian Maia at UFC Fight Night 129 in May.
