WATCH: Four cops on hand during very intense Conor McGregor-Nate Diaz staredown

Fight Night can't come soon enough.

Nate Diaz and Conor McGregor are ready for war. If the "handbags" at the pre-fight press conference wasn't enough to convince you of that, then their intense staredown at the official weigh-ins definitely will. Four Las Vegas cops were on stage to ensure that nothing broke out between the two fighters and Dana White had his work cut out separating the two UFC superstars as they talked trash and tried to psych each other out. When McGregor got hold of the mic, he had this to say to his opponent,

"He should have killed me when he had the chance, because now I'm back and I'm going to kill you and your whole fucking team. You and them bitch kids."

Meanwhile, Diaz seems convinced that the emotional McGregor is already a beaten man heading into the rematch.

"I train always hard to kill. He already dead from the last time. This is a new guy. So it's kill or be killed again. USA, motherfucker!"
