Maynard vs. Diaz will act as the main event, with Escudero vs. Dunham serving as the co-headlining attraction of the night.
The event has been scheduled for January 11 from the Patriot Center in Fairfax, Virginia, airing live on Spike TV.
The bout between Maynard and Diaz will be a rematch to the pair’s meeting during their mutual stint on fifth season of The Ultimate Fighter. A bout Diaz won via second round guillotine choke.
Maynard has gone undefeated in his stint with the UFC, putting together six consecutive victories over the likes of Frankie Edgar, Jim Miller and Roger Huerta, while Diaz submitted Melvin Guillard in his last outing after a pair of losses to the likes of Joe Stevenson and Clay Guida.
The lightweight winner of TUF 8, Escudero recently knocked Cole Miller senseless in his first outing since the TUF Finale during UFC 103, while Dunham is fresh off of back to back Octagon victories over Per Eklund and Marcus Aurelio. Both men sport undefeated records.
