Shortly before today's weigh-in for UFC Live 4 - Marquardt vs. Story, which was scheduled for 4 p.m. EST, UFC president Dana White posted a video on his official Twitter account stating that he has fired main event fighter Nate Marquardt.

"He failed his medicals. Not only is he out of this fight and out of the main event on Versus, he will no longer be with the UFC,” stated the unhappy UFC boss.
