UFC Fight Night 20 which is likely to take place in Fairfax, Virginia (aka 6th-Round.com’s backyard) has now received a main event as well as an additional under card bout.

Lightweights Gray Maynard (9-0) and Nate Diaz (15-4) will meet in the Octagon to headline the evening. Maynard is expected to receive a title shot if he bests the always scrappy submission expert Diaz.

On the under card we will likely see the addition of two other lightweights both coming off of wins in Kyle Bradley (14-6) vs. Rafael dos Anjos (12-4).

Hitting the Patriot Center on January 11 will be a slew of solid fights as we’ve come to expect from the Fight Night series. Always fun to note is that the main card will air for free on Spike TV. The currently rumored line-up is as follows…

Gray Maynard vs. Nate Diaz
Josh Koscheck vs. Mike Pierce
Chris Leben vs. Jay Silva
Rick Story vs. Jesse Lennox
Efrain Escudero vs. Nick Lentz
Tom Lawlor vs. Aaron Simpson
Mike “Joker” Guymon vs. Rory MacDonald
Kyle Bradley vs. Rafael dos Anjos
