LAS VEGAS -- Uriah Hall's beef with Rafael Natal allegedly started when Natal blocked Hall from working with trainer Phil Nurse.
It escalated with a shoving match between the two New York City transplants at Friday's UFC 187 weigh-ins.
It reached a crescendo at the start of their middleweight showdown Saturday night at the MGM Grand Garden Arena. Before the fight, Hall (10-5) got in Natal's face, had to be sent back to his corner, and twice came back out to the center of the Octagon.
Then Natal opened the fight with a low kick that many considered intentional.
