The UFC 158 pre-fight press conference airs later today and it’s shaping up to be a must-see so be sure to watch it unfold live right here on

The big question here is whether headlining title challenger Nick Diaz will actually show up? He failed to do so at a presser back in 2011 that caused his first title fight with Georges St.Pierre to be cancelled, and he’s already been up to his old tricks yesterday, failing to turn up for the media workout session.

Dana White has made it clear Diaz has to attend today’s presser or he’ll be in trouble so surely he will do so. If he does then there’s always the chance that we’ll get round two of the war of words between Diaz and GSP which began during a heated media conference call last week.

Only one way to find out – tune in to the streaming video below which will cover the full presser live starting at aprox 1pm ET (5pm UK).
