Flinched! Conor McGregor vs Nate Diaz staredown pic, video from UFC 196 weigh ins

The official UFC 196 weigh in event for the upcoming "McGregor vs. Diaz" pay-per-view (PPV) extravaganza went down earlier today (Fri., March 4, 2016), inside MGM Grand Garden Arena in Las Vegas, Nevada, host venue for tomorrow night's big shebang.

And after Thursday's pre-fight press conference nearly ended in a knock-down, drag-out brawl (relive the chaos here), all eyes were firmly focused on welterweight headliners Conor McGregor and Nate Diaz, who once again were asked to square off.

Here's what happened:

In the women's bantamweight championship co-main event, Holly Holm came nose-to-nose with Miesha Tate roughly 24 hours before they face off with "The Preacher's Daughter" putting her newly-won 135-pound strap on the line against "Cupcake."
