After winning the 2006 Pride Openweight Grand Prix, Mirko Filipovic joined the UFC, where he was expected to compete for the UFC Heavyweight Championship.
After finishing Eddie Sanchez in his first Octagon appearance, Filipovic was given a fight with Gabriel Gonzaga to determine the top contender in the division.
Although Gonzaga had won his last five fights, few gave him a chance against the Croatian kickboxer. If Gonzaga was going to defeat Filipovic, it certainly wasn't going happen on his feet—or was it?
Filipovic had produced a highlight reel of head kick knockouts throughout his career leading into this fight, but it was Gonzaga who gave Filipovic a taste of his own medicine with this career-altering knockout.
