It has been a busy 24 hours for the UFC.

There have been a number of big bouts announced, most of which will take place at UFC 136. As always, MMAFighting.com was the first to report on many of the contests.

– In the biggest news, Frankie Edgar and Gray Maynard will finally settle the score in a lightweight championship clash at UFC 136 on Oct. 8 from the Toyota Center in Houston. This is the second attempt for the UFC to put on this bout, as the two were originally schedule to fight at UFC 130, but both suffered injuries.

– The UFC also announced via Twitter that Jose Aldo will defend his featherweight championship against Kenny Florian at UFC 136. This will be Florian’s third attempt to win UFC gold while Aldo will be defending his UFC strap for the second time.

– Also set for the UFC 136 card in Houston is another lightweight showdown when Melvin Guillard faces Joe Lauzon. Guillard has quickly skyrocketed up the lightweight ladder with five-straight wins. However, Guillard has struggled in the past with submission fighters and Lauzon is a pitbull on the ground. Lauzon won’t back down from Guillard and the first five minutes of this fight should be very explosive.

– A third bout for UFC 136 was announced as middleweights Demian Maia and Jorge Santiago will square off. Both fighters are coming off of losses and need this win in order to remain a top-10 contender in the division.

– For UFC 137 on Oct. 29 in Las Vegas, heavyweight strikers Matt Mitrione and Cheick Kongo will battle it out. Both are coming off KO wins at UFC Live on Versus 4, with Kongo knocking out Mitrione’s friend, Pat Barry. This will be the biggest test to date for Mitrione, who is now 6-0 in his pro career.

If you weren’t on Facebook before, the UFC is giving you plenty of reason to do it now.

Once again, the premiere MMA organization is airing preliminary fights for an event on the social media network.

This Sunday, UFC Live 4 featured four main card bouts, but will have 7 prelim fights, and all will air live on Facebook, starting at 4:55 p.m.

Now, I am a big fan of watching any fight, but the UFC Live 4 prelims are really an impressive set of bouts.

The first fight of the night will feature Michael Johnson, who was a punch or two away from winning the Ultimate Fighter Season 13.

Then you have fighters like Joe Lauzon and Daniel Roberts taking the octagon and an impressive lightweight showdown from Charles Oliveira and Nik Lentz.

You also have the featherweight debuts from Joe Stevenson and Tyson Griffin. Griffin will face off with Manny Gamburyan in a bout that I personally think will be a PPV quality fight.

I have to hand it to the UFC. Years ago, you used to have to buy the event DVD to watch prelim fights, but now, they are providing them through all sorts of means, including YouTube and Facebook.

So, once again, if you haven’t “Liked” the UFC on Facebook, you better do it before 5 p.m. tomorrow, or you are going to miss out on some impressive fights.
