That isn't in Russia. The referee is called James Bruno.
The referee James Bruno explains what happened: "First I accidentally knock the guy over while seperating the two. I then apologize and pat the guy on the headgear. As I walk away he mushes the back of my head and when I turn around he tells me to go "F" myself. If you look extra closely you can see me knock away his left hand which was on my neck first before I slammed him. Earlier in the fight the guy was acting like a punk, talking smack and disrespecting everybody. He totally deserved it, everyone who was there agreed".
