After securing a fourth-round rear naked choke in the biggest fight of his career, Khabib Nurmagomedov sullied his sublime in-cage performance with a reprehensible brawl after the bell.

Moments after forcing Conor McGregor to tap to a rear-naked choke that wasn’t fully under the chin, Nurmagomedov vaulted the Octagon cage and attacked Dillon Danis in the Irishman’s corner.

Following the champions actions, police officers and arena officials looked to separate the two but tensions spilled over into the cage as members from Khabib’s team entered the Octagon and attacked McGregor.

Fortunately, no notable damage or injury was done to any person involved in either scuffle but the end result of a heated rivalry has left a black eye on the sport of MMA.
