Ultimate Fighting Championship (UFC) this evening announced a new addition to The Ultimate Fighter (TUF) 16 Finale card, which will take place at the Hard Rock Hotel and Casino in Las Vegas, Nevada, on Dec. 15, 2012.

Lightweights Melvin Guillard and Jamie Varner will square off in a battle between two 155-pound fighters both in need of a win.

"The Young Assassin" has had a hard time living up to his moniker as of late, losing three of his past four fights, all first round finishes. "C4" is also coming off a loss, a third round submission loss to Joe Lauzon in a bout that earned the two fighters "Fight of the Night" honors at UFC on Fox 4 in Los Angeles, Calif., on Aug. 4, 2012.

TUF 16 Finale card will be headlined by a Heavyweight mash up between coaches Shane Carwin and Roy Nelson. There has also been an announced fight between fellow heavyweights Pat Barry and Shane del Rosario, as well as a Featherweight contest featuring TUF alum Jonathan Brookins taking on Dustin Poirier.

Welterweights Mike Pyle and James Head will also go head-to-head in a pairing of two fighters on two-fight win streaks looking to keep their respective runs alive.
