The Ultimate Fighter 12 Finale.

The Ultimate Fighter: Team GSP vs Team Koscheck Finale, also referred to as The Ultimate Fighter 12 Finale was a mixed martial arts event held by the Ultimate Fighting Championship at the Palms Casino Resort in Paradise, Nevada, United States on December 4, 2010. This was the first event in the UFC to integrate the featherweight & bantamweight classes from World Extreme Cagefighting, which folded later that month. It was also the first event to feature a then-contracted WEC lightweight fighter (Pablo Garza) in a UFC contest, though he debuted in the UFC at featherweight.
