Lightweights Melvin Guillard and Jamie Varner have now agreed to face-off at the upcoming UFC on FX finale card. The card is set to take place on Dec. 15 in Las Vegas, for the TUF 16 finale. Headlining the action is TUF coaches Roy Nelson vs. Shane Carwin and scheduled t co-headline is fellow heavyweights Pat Barry vs. Shane del Rosario.

Both Guillard and Varner will be stepping off of Fight of the Night performances in losing efforts. Varner stepped in as a late replacement against Joe Lauzon in Aug., where he lost via triangle, after a back and forth battle.

Guillard put on likely the most exciting 76 second fight in UFC history, rocking his opponent and friend Donald Cerrone. Unfortunately the slightly overzealous Guillard had suffered a KO shortly after via headkick combo.
