Conor McGregor, Nate Diaz Nearly Brawl at UFC 196 Presser

Conor McGregor and Nate Diaz

With UFC 196 taking place on Saturday (March 5), headliners Conor McGregor and Nate Diaz faced off at the press conference this week... and nearly brawled.

The two fighters took the stage for the customary staredown, with UFC president Dana White standing in the middle... but things got a little heated. As Diaz put up his fists for the pose, McGregor swiped his hand away, prompting him to attempt to go after him.

Luckily, security quickly intervened... stopping UFC 196 from happening right then and there.

Watch it go down below.

McGregor and Diaz will finally will face off on Saturday night, but will see each other once more on Friday, during the UFC 196 weigh-ins.
