Nick Diaz vs Carlos Condit staredown pic from UFC 143 weigh-ins

The UFC 143: "Diaz vs. Condit" weigh-in event took place today (Fri., Feb. 3, 2012) in Las Vegas and that means staredowns with all the major players.

That includes the two headliners for tomorrow night's event at the Mandalay Bay Events Center, Nick Diaz vs. Carlos Condit. For those hoping for some fireworks, sorry, nothing to see here. Diaz kept it professional, as did the always dapper "Natural Born Killer."

Heavyweights Roy Nelson and Fabricio Werdum will hook 'em up in the co-main event of the evening while welterweight bad boy Josh Koscheck makes his return to battle Mike Pierce. See them all stare at each other after the jump.
