LIVE: Watch Conor McGregor and Nate Diaz square off for the first time in California

It's lucky that this isn't being broadcast on national television because the censor in charge of the beep button would be quickly overwhelmed.

Conor McGregor and Nate Diaz are two of the greatest trash talkers in the history of the sport and they're coming face to face for the first time since the announcement that they are set to clash in the main event of UFC 196. The headliner was originally scheduled to be a lightweight title fight between champion Rafael dos Anjos and 'The Notorious' but dos Anjos was forced out of the bout with a fractured foot. https://www.youtube.com/watch?v=x0Ze86N21ro And through the bevy of offers to stand in, Diaz was selected to meet McGregor in a welterweight clash on March 5. The mental warfare gets underway tonight, at a press conference in Torrance, California and it all gets started at 9 PM GMT. Prepare for fireworks!
