On October 29, Georges St-Pierre puts his welterweight title on the line against "The Natural Born Killer" Carlos Condit.
In the co-main event, a No. 1 contender fight is going down in the welterweight division between former UFC welterweight and lightweight champion BJ Penn and former Strikeforce welterweight champion Nick Diaz.
Also featured on the main card is a heavyweight bout between The Ultimate Fighter 10 alum Matt "Meathead" Mitrione and Cheick Kongo.
Mitrione is 5-0 in his UFC and MMA career, and a win would catapult him into the top-10 of the heavyweight division.
Check out Mitrione and nine more of the best up-and-coming fighters in the UFC.
"Meathead" was featured on season 10 of The Ultimate Fighter, and he was one of a few fighters who had no prior professional experience.
Mitrione ended up losing in the quarterfinals to James McSweeney, but since debuting in the UFC, he has gone 5-0 with four (T)KOs and one fight-of-the-night award .
He gets a chance to rise from up-and-comer to contender when he takes on Cheick Kongo at UFC 137.
Dave Herman was scheduled to fight at UFC 136, but unfortunately a failed drug test (marijuana) forced Herman off the card.
Nevertheless, Herman certainly has the potential to be a top heavyweight, and his record of 21-2 attests to that.
Not only does he have an impressive record, but the fact that one of his losses was a DQ and 20 of his wins have been finishes should show that he's got some skill.
Herman is currently 1-0 in the UFC, with one fight-of-the-night award.
Alexander Gustafsson is a prospect in the light heavyweight division, where he is ranked about 10th.
Gustafsson is 4-1 in the UFC, with two finishes by submission, and two by (T)KO, and 12-1 overall in his career. His only loss came to Phil Davis.
Gustafsson is 24 years old, and after his most recent win over Matt Hamill, Jon Jones tweeted that he would likely end up facing him.
Phil Davis is a fighter in the light heavyweight division who is well on his way to the top.
Davis is one of the most accomplished wrestlers in the entire division. He placed in the top seven during all four years of college at Penn State, including one championship and one second-place finish.
Davis is pegged by many as the one fighter in the division who may challenge Jon Jones at some point in the future.
Davis is 5-0 in the UFC, with one submission-of-the-night award.
Rory MacDonald has been called "the future GSP" by GSP himself.
That's quite a compliment.
MacDonald is a bright young prospect in the welterweight division, and his only career loss came to the next welterweight title challenger, Carlos Condit.
Aside from that one blemish, MacDonald is 12-1, with 11 finishes.
MacDonald is 3-1 in the UFC, with one fight-of-the-night award.
Jake Ellenberger recently made a huge statement to the welterweight division, when he knocked out a top-10 pound-for-pound fighter in Jake Shields in a mere 57 seconds.
Ellenberger is one of the more experienced welterweights, and at only 26 years of age, he already has 31 fights.
Ellenberger's only loss in the UFC came at the hands of Carlos Condit, but soon enough he may get a chance to avenge that loss.
Ellenberger is 5-1 in the UFC, with one knockout-of-the-night award.
Tony Ferguson is the season 13 winner of The Ultimate Fighter in the welterweight division, and he currently fights in the lightweight division.
Ferguson is known as a finisher, as he has finished his opponent in 11 out of his 12 victories. He also finished all three of his opponents on The Ultimate Fighter.
In Tony's last fight, he broke Aaron Riley's jaw and won via TKO at the end of the first round.
Ferguson is 2-0 in the UFC, with one knockout-of-the-night award.
Edson Barboza is an undefeated prospect in the lightweight division; he also has a professional kickboxing record of 25-3.
Barboza was last seen putting on a fight-of-the-night performance against Ross Pearson at UFC 134, in front of his home-country fans.
Barboza should soon make a name for himself in this muddled lightweight division.
Barboza is 3-0 in the UFC, with two fight-of-the-night awards.
Yuri Alcantara is a name you probably haven't heard before, but you will.
Alcantara is a fighter in the featherweight division, with a record of 26-3 with 23 finishes.
He recently made his UFC debut at UFC 134, where he defeated Felipe Arantes by unanimous decision.
Alcantara is 2-0 in the UFC/ WEC, with one first-round knockout.
Renan Barao is pegged by many as the man to take down Dominick Cruz.
Barao is another very experienced fighter, with 28 fights at only 24 years of age.
Barao has a record of 26-1 [1 NC] with 6 (T)KO wins and 12 submission wins.
Barao is 3-0 in the UFC/ WEC, with two submission victories.
