It’s no secret that Chael Sonnen and Wanderlei Silva don’t like each other. On March 9, via the UFC’s Fight Pass online subscription service, fans will get to see that dislike throughout a full season of The Ultimate Fighter, where the two serve as coaches for a group of middleweight and heavyweight UFC hopefuls.

As much attention as the coaches have received, the real focus of the show should be on its contestants. With that in mind, here is a preview of the 16 middleweights who will vie for the eight middleweight spots in The Ultimate Fighter: Brazil 3 house.

Cristiano Ribeiro Lopes Pontes (4-1) - In the spirit of Kenny Florian, Cristiano “Ferrugem” is a lightweight who will move up two weight classes to compete as a 185-pounder on The Ultimate Fighter. The X-Gym fighter made his pro debut in 2010, but didn’t compete again until 2012. He won his first four fights, including three by way of stoppage. In his most recent outing, the Bitetti Combat veteran made his first appearance under the Jungle Fights banner in a losing effort against Ary Santos, who submitted Ferrugem in just over three minutes. At age 34, the native of Rio de Janeiro is among the oldest fighters seeking a spot in the TUF Brazil 3 house.

Douglas Moura Silca (4-1) - Douglas Moura’s official record varies. The UFC’s press release lists Moura with a 3-1 record, but, according to the Sherdog fighter database, the 29-year-old picked up a fourth victory just a week before the UFC conducted its open tryouts for the reality show. Further muddying the waters is the database’s listing of a December 2011 amateur victory, which came after Moura already had two pro wins. The native of Rio de Janeiro made his pro debut in May 2011 and won three bouts under the Jungle Fights banner (plus the amateur contest at a Watch Out Combat Show event). Moura suffered his only defeat via a 72-second TKO in his fourth pro outing, but rebounded with the victory just one week before the TUF tryouts. The Team Nogueira and Behring Jiu-Jitsu product has three wins by submission and one via TKO. He has only been out of the first round once in his career.

Giuliano Brescianini Arante (5-1) - Giuliano Brescianini Arante made his pro debut less than two years ago. The Octagon Fight product went 1-1 through his first two fights, but he is now riding a four-fight winning streak. “Alemao” suffered his only loss via TKO. The 29-year-old has stopped three opponents by way of submission and picked up decisions in his other two wins. Arante hails from Campo Grande, Mato Grosso do Sul.

Guilherme Vasconcelos (3-1) - Guilherme “Bomba” Vasconcelos, who typically fights at welterweight, is another fighter moving up in weight for his crack at The Ultimate Fighter. Since making his pro debut in 2012, the 27-year-old has made appearances with Watch Out Combat Show, Shooto Brazil and Jungle Fights. The Titi Jiu-Jitsu product has utilized a rear-naked choke to submit two opponents and finished a third via first-round TKO. His lone loss came on the scorecards against Pride veteran Daniel Acacio, and his pro debut victory came against TUF castmate and veteran fighter Wendell Oliveira Marques. The native of Belo Horizonte is a highly decorated Brazilian Jiu-Jitsu practitioner and has graced the podium as a World champion in BJJ competition.

Ismael de Jesus (9-4-1) - Ismael “Marmota” de Jesus is among the most experienced welterweight contestants on the show. The 34-year-old, who hails from Goiania, made his pro debut in 2007 and went just 1-2 through his first three fights, all of which went to a decision. Marmota bounced back with a six-fight undefeated streak that included five wins, four of which were finishes. He ended the streak when he dropped a split verdict to Caio Magalhaes. Following the loss to Magalhaes, Marmota picked up three more wins, but he enters the TUF competition on the heels of a decision loss in his most recent outing. Training out of the Fernando Boi Team and Nova Uniao, de Jesus has never been stopped in a fight. In the win column, he holds an equal amount of victories via submission, knockout and decision, with three apiece.

Joilton Santos (9-2) - Joilton “The Peregrino” Santos made his pro debut in 2011 and shot out of the gates with four wins through five fights, with the remaining bout ending in a no-contest. The native of Campina Grande, Paraiba, lost two of his next three, but he has since recovered with four consecutive wins, including three via stoppage. Santos trains out of Benkei MMA System, Team Alexandre Pequeno and Comando Barra. The 21-year-old has four submission victories and three wins by some form of knockout. He has been finished on just one occasion, via submission.

Jose Roberto Rocha (5-0) - Jose “Negão” Roberto Rocha is a perfect 5-0 through six fights, with the other bout ending in a no-contest. The 26-year-old has stopped all but one of his opponents. Since making his pro debut in 2011, the Montanha Team fighter has submitted two foes and scored TKO victories over two more. The native of Uba, Minas Gerais, is coming off a decision victory in his lone fight of 2013.

Marcio “Lyoto” Alexandre Junior (12-0) - In terms of success rate, Marcio “Lyoto” Alexandre Junior’s spotless record through 12 fights certainly makes him a favorite among the middleweight contingent on this season of The Ultimate Fighter. The Team Tavares fighter made his pro debut in 2010, but didn’t return for his sophomore appearance until 2012. Though he is listed as a welterweight, Alexandre will step up to 185 pounds for the reality series. With a tendency for quick finishes—he’s only seen the second round once in his career—the 24-year-old from Florianopolis is a lethal threat to any of his castmates. Alexandre does have two submission wins, but his bread and butter is his striking, which has led to 10 wins by some form of knockout. “Lyoto’s” background is in karate.

Markus Perez Echeimberg (3-0) - Markus “Maluko” Perez Echeimberg has yet to hit his one-year anniversary as a pro fighter. The 25-year-old debuted in 2013 and notched three wins—a TKO, a unanimous decision and a submission—in the span of approximately five months. The Gracie Fusion and Veras TK product hails from São Paulo.

Paulo Henrique Costa (3-0) - Paulo Henrique “Borrachinha” Costa is one of the youngest middleweight contestants on the reality series. The 22-year-old, who is listed as a light heavyweight in the Sherdog fighter database, could turn out to be one of the bigger 185ers in the cast. The Rubens Dorea Team product made his pro debut in 2012 and has fought just three times. All three of the Belo Horizonte native’s fights ended in under three minutes, and all by way of TKO.

Pedro Paulino (3-0) - Pedro “Vinagre” Paulino has not had an official fight since his decision win over Brayner Caramalac in December 2012. The Campo Grande, Mato Grosso do Sul, native made his pro debut in 2011 and has picked up three victories. The 29-year-old trains out of Pantanal Fight Team and has two submission victories in his brief MMA career.

Ricardo Abreu (4-0) - Ricardo “Demente” Abreu may have multiple Brazilian Jiu-Jitsu World championships to his name, but he’s made a habit of using his fists in MMA competition. The 29-year-old BJJ ace made his pro MMA debut in 2011 with a 61-second armbar submission win, but he has followed the performance with a trio of astonishingly quick knockouts—24 seconds, 59 seconds and 24 seconds in duration. Abreu has trained with Nova Uniao and Black House, served as Tito Ortiz’s personal BJJ coach with Team Punishment and also has affiliations with the Wand Fight Team. Given his background and his well-rounded skill set, the São Paulo native has to be considered a favorite in the TUF competition.

Wagner Silva Gomes (3-0) - Wagner “Wagnão” Silva Gomes made his pro debut in 2012 and has won all three of his fights. The Tata Fight Team product has two first-round submission wins to go along with a split decision victory. The native of Viçosa, Minas Gerais, is 26 years old. His most recent fight came under the banner of the Watch Out Combat Show promotion.

Warlley Alves de Andrade (6-0) - At age 23, Warlley Alves de Andrade is among the youngest members of the middleweight class of this edition of The Ultimate Fighter. He made his pro debut in 2011 with a 34-second submission victory, and he has since added another sub-minute submission win to his resume. The native of Governador Valadares, Minas Gerais, trains out of the X-Gym and tends to submit his opponents, though he has scored one TKO victory and went the distance in two of his fights.The Jungle Fights veteran normally competes as a welterweight, but he’ll move to middleweight for his shot on The Ultimate Fighter.

Wendell Oliveira Marques (23-7) - With 30 fights on his record, Wendell Oliveira Marques has more than twice the experience of any other middleweight in the cast. “War Machine” made his pro debut in 2006, but he went just 2-4 through his first six fights and 6-6 through his first 12 outings. Since 2009, however, the Crazy Fight Team, Gracie Fusion and Black House product has gone a stellar 17-1. His only loss in that 18-fight span came courtesy of TUF castmate Guilherme Vasconcelos. The 30-year-old native of Rio de Janeiro has notched wins over the likes of Flavio Alvaro and Alexandre Barros, and he has suffered losses to Hernani Perpetuo and Edilberto de Oliveira. He has 11 wins by some form of knockout and three by way of submission, but he has also suffered four submission losses and two TKO defeats. Marques is another welterweight moving to middleweight for the reality series.

Willian Steindorf (3-0) - Willian Steindorf, like many of his fellow castmates, has but a few fights on his record. What differentiates him from the rest of the middleweight competitors is that he has only fought once in the last five years. The 24-year-old made his pro debut in 2008 and fought again in 2009, but he didn’t return to action for his third outing until 2013. All three of the Porto Alegre native’s win came in under three minutes via armbar.
