Vine: Fighter disqualified for intentional headbutt after opponent pulls his hair

That's one, clear way of getting disqualified

Cody McKenzie did not last too long following his return from a self-imposed mixed martial art exile. The Alaskan fighter took exception to Andrew McInnes niggling, hair-pulling antics during their World Series of Fighting [WSOF] 18 bout. Towards the end of the first round, right out of the blue and with McKenzie wailing on his stricken opponent, he launched into a diving header into McInnes' skull. The referee immediately called the DQ. Hat-tip: MMA Fighting
