An exciting welterweight war featuring Matt Riddle vs. Luis Ramos hits the undercard of the UFC 141: "Lesnar vs. Overeem" mega-event tonight (Dec. 30, 2011) at the MGM Grand Garden Arena in Las Vegas, Nevada.

Both coming off losses, Riddle and Ramos are looking to prolong their stay with Ultimate Fighting Championship (UFC) with a big win in "Sin City."

Making his debut at UFC 134: "Silva vs. Okami," Ramos was knocked out just 40 seconds into the opening round by Erick Silva, which is not a great way to begin your UFC career. Riddle on the other hand, isn't exactly making waves in the promotion's 170-pound division either, losing his last two outings via unanimous decision.

Now, both welterweights hope to keep their place on the ZUFFA roster and a win tonight would certainly go a long way in accomplishing that while a loss could spell disaster for either combatant.

But who will prevail?

With all of his eight mixed martial arts (MMA) bouts under the UFC banner, Riddle has been a mainstay in the welterweight division, though another defeat could mark the end of his UFC career with two consecutive losses already preceding him.

The former Ultimate Fighter (TUF) participant kick-started his MMA career with an impressive 5-1 record before running into Sean Pierson and Lance Benoist, who both earned unanimous decisions over "Monster Mash."

Ramos hopes to put on a better showing than he did in his UFC debut when Silva knocked him out in under a minute. Though both welterweights aren't knocking on the door of a title shot, they are fighting for something of importance: relevance in the UFC's 170-pound division.

Can Ramos prove to the MMA community that his debut was not enough to judge his full capabilities by handing Riddle his third consecutive loss, or will Matt keep his place in the only fight organization he has ever known?
