Three days before they’re set to face off at UFC 202 in Las Vegas, Conor McGregor and Nate Diaz got into it at the pre-fight press conference. While the two fighters didn’t lay hands on each other, they had to be separated before Wednesday's news conference abruptly ended.

Diaz took questions from the media before McGregor arrived late, and he headed for the exit while McGregor was still at the podium. With the two fighters exchanging words and cursing at each other as Diaz and his team walked out, Diaz tossed what appeared to be a water bottle in McGregor’s direction. McGregor fired back with a water bottle of his own, and both fighters had to be held back.

"Shut your f******* mouths, you’ll do nothing! You’ll do f******* nothing! Not one of you will do nothing! Get the f*** out of here!” McGregor yelled at Diaz and his team before the bottles started being thrown.

McGregor and Diaz will meet in Saturday’s main event in what has become one of the most-anticipated rematches of all time. Diaz handed McGregor his first ever UFC loss at UFC 196 in March when he forced the Irish fighter to tap out in the second round.
