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 heavyweights who will vie for the eight heavyweight spots in The Ultimate Fighter: Brazil 3 house.

Alexandre Machado (6-1) - Alexandre “Bebezao” Machado is a smallish heavyweight fighting out of Machado Team in Niterói, Rio de Janeiro. The 30-year-old made his pro debut in 2007, but didn’t return to action again until more than two years later. He won his first four fights before suffering his lone defeat in 2012. Machado has since returned to the win column with a pair of victories. Though he has scored a knockout, a TKO and three submission wins, his most notable victory is his one decision win, which came against Mikhail Zayats. Machado has a diverse resume that features stops in the M-1 Global, Peru FC and Jungle Fight promotions.

Antonio Carlos Junior (3-0) - The TUF middleweight class doesn’t hold a monopoly on World champion Brazilian Jiu-Jitsu competitors on this season of the reality series. Two-time World champion Antonio “Cara de Sapato” Carlos Junior gives the heavyweight contingent its BJJ ace. The 23-year-old is a native of João Pessoa, Paraiba, and typically fights at light heavyweight. The Champion Team and Nordeste Jiu-Jitsu product made his pro debut in July 2013 and has quickly racked up three submission wins. He has never gone beyond the first round, and two of his contests ended before the two-minute mark.

Antonio Paulo Branjao (3-0) - Antonio “Montanha” Paulo Branjao is another light heavyweight competitor moving up to heavyweight for his opportunity on The Ultimate Fighter. The 25-year-old trains out of Team Nogueira and hails from Uba, Minas Gerais. He made his pro debut in 2012 and has three victories by some form of knockout. All of his fights have ended in the first round.

Bruno Silva (9-4) - The UFC may have opted to seek heavyweights for this season of The Ultimate Fighter, but it seems that the best heavyweight options out there are really light heavyweights. Bruno “Blindado” Silva is among the group of 205-pounders to head to heavyweight for their shot on the reality series. Silva is among the most experienced heavyweights in the cast. The 24-year-old has been very active since his debut in 2010, racking up nine wins in 13 fights over the course of three years. Of his victories, eight have come via knockout or TKO. Meanwhile, Blindado has proven to be weak on the mat, where he has been submitted three times. The Nocaute Fight product, who hails from João Pessoa, Paraiba, is riding a four-fight winning streak, but he lost to castmate Felipe Diego Dantas de Oliveira in 2012.

Edgard Castaldelli Filho (12-4) - Team Nogueira’s Edgard “Magrao” Castaldelli Filho is the most experienced heavyweight on the reality series. He made his pro debut in 2001, but didn’t engage in his sophomore outing until 2004. He doesn’t have a reputation for finishing opponents. The 34-year-old has seen the scorecards in more than half of his fights, with seven wins and two losses to show for those efforts. Another natural light heavyweight, Magrao has been on the losing end of the TKO in contests against UFC veterans Fabio Maldonado and Thiago Perpetuo. The Rio de Janeiro native does hold a victory over UFC fighter Igor Araujo.

Everton Rocha (3-1) - Everton “Gigante” Rocha isn’t so giant. In fact, he’s yet another light heavyweight to join this edition of The Ultimate Fighter as a heavyweight. The 31-year-old blasted out of the gates in 2012 with a 64-second TKO victory in his pro debut. His second fight didn’t go so well, with the Team Nogueira fighter succumbing to a heel hook in just 27 seconds. The native of Rio de Janeiro righted the ship with back-to-back submission wins. He has appeared twice under the Shooto Brazil banner.

Felipe Diego Dantas de Oliveira (6-0) - If you’re reading this preview in order and guessed that Felipe Diego “Monstro” Dantas de Oliveira is a natural light heavyweight, you’d be correct. The native of Natal, Rio Grande do Norte, made his pro debut in 2005 and competed once a year until 2007. The Kioto product stepped away from MMA until 2012, when he returned with a victory over castmate Bruno Silva. The 30-year-old loves the arm-triangle choke and has used it to submit five of his adversaries in the first round.

Fernando Camoles (4-1) - Brazilian Top Team’s Fernando Camoles will enjoy the luxury of being one of the bigger heavyweights in the TUF house. The 28-year-old made his pro debut in 2011 and immediately launched into a four-fight winning streak. His most recent fight, however, ended in disappointment when Camoles dropped a unanimous verdict to Fabio Marongiu at a Watch Out Combat Show event. The São Caetano do Sul native has finished two opponents via strikes and two by way of submission, and three of his victories came in the first round.

Goncalo Salgado (7-2) - Goncalo Salgado checks in as a truly unique member of TUF Brazil 3’s heavyweight cast. Salgado is listed as a 308-pound super heavyweight in the Sherdog fighter database, and he’s also the only fighter in the cast from outside of Brazil—he hails from Portugal. The giant made his pro debut in 2006 and compiled a 5-1 mark through 2007. He returned to the sport in 2009 and recorded two more wins and a loss by the end of 2011, but he has not fought since then. Salgado’s most recent outing came under the M-1 Global banner. The 33-year-old has been submitted once and lost one fight via TKO. He has one submission win, but tends to knock out his opponents.

Guilherme Viana (4-1) - Guilherme Viana is another light heavyweight among the heavyweight contingent on the reality series. The Ruas Vale Tudo product made his pro debut in 2012 and won his first three fights. His lone defeat came via split decision against UFC veteran Rodney Wallace, and the 27-year-old has since rebounded with another victory. The Porto Alegre native has three TKO victories and one win via submission. Viana has trained alongside Glover Teixeira and Pedro Rizzo. He is a veteran of the Watch Out Combat Show promotion.

Job Kleber Melo (3-1) - Job Kleber Melo is a smallish heavyweight. The Beto Padilha Team fighter made his pro debut in December 2012 and notched three stoppage wins. The 34-year-old native of Rio de Janeiro tasted defeat in his most recent outing, a loss to Wagner Ribeiro just one week before the UFC’s open tryouts for the reality show. Melo has two submission wins and one victory by way of TKO. His lone defeat came via TKO.

Jollyson Francino Sosatleta (2-0) - Jollyson Francino Sosatleta has lacked luck in his MMA career. After debuting in 2011 and scoring wins in his first two outings, the Nova Uniao Pernambuco product has seen his last two fights end in no-contests. The first of those no-contests ended when the 30-year-old was injured by a headbutt. The second of those fights featured an outcome that was overturned by the promoter. The native of Recife is listed as a middleweight in the Sherdog fighter database and could check in as one of the smallest heavyweights in the cast. He has one submission win and one victory by way of a decision.

Marcos Rogerio “Pezao” Lima (11-2-1) - Marcos Rogerio Lima is a natural middleweight who is moving up two divisions for his opportunity on The Ultimate Fighter. With 15 fights under his belt, the 28-year-old is among the most experienced heavyweights in the cast. He debuted in 2009 and won his first eight fights. Among those wins, Pezao earned a unanimous nod over Pride and WEC veteran Paulo Filho. The 011 MMA Team product’s next fight came in the Strikeforce cage, where he dropped a decision to UFC veteran Mike Kyle. The São Paulo native suffered his only other career loss in his very next bout against Carlos Eduardo, who knocked out Pezao in the second stanza. Lima recovered with three straight wins before fighting to a draw in his most recent bout. He has scored eight of his wins by some form of knockout.

Richardson Moreira (7-1) - If you don’t succeed the first time, try, try again. That could be the motto of Richardson “Rick Monstro” Moreira. The 29-year-old was on the losing end of a decision verdict against Daniel Sarafian in a qualifying round middleweight fight on The Ultimate Fighter: Brazil. Now, the former middleweight and light heavyweight returns to TUF as a heavyweight. The native of Campinas made his pro debut in 2010 and scored first-round wins in his first five fights, including a submission of UFC veteran Antonio Mendes. He suffered his only loss via submission in the first of his three fights in 2013. The Team Nogueira fighter has five submission victories, all in the first round, and has scored the remainder of his wins by some form of knockout.

Thiago Santos (11-3-1) - Thiago “Big Monster” Santos will be the most familiar cast member to viewers who reside in the United States. The 27-year-old competed in the season-five and season-seven Bellator heavyweight tournaments and was involved in the bizarre conclusions of a pair of tourney fights with Eric Prindle, including the season-five tournaments final, which ended in a no-contest when Santos kicked Prindle in the groin. He picked up a win in the rematch when Prindle landed a kick to his groin. The Rio de Janeiro native made his pro debut in 2007 and won 11 of his first 13 fights before running into tougher competition inside the Bellator cage. The Team Nogueira fighter is on a two-fight skid following first-round stoppage losses to Rich Hale and Javy Ayala. Santos has defeated the likes of UFC veteran Neil Grove. He has five wins by submission and two by some form of knockout. He’s also prone to bizarre finishes, as evidenced in the two fights with Prindle and in an additional disqualification victory. Despite his two-fight losing streak, Santos’ size and experience in Bellator make the Brazilian Jiu-Jitsu black belt a favorite among the heavyweights this season.

Vitor Miranda (9-3) - This season of The Ultimate Fighter has a healthy serving of grappling aces, but there’s only one standout striker among the 32 fighters. That would be K-1 Brazil 2005 and K-1 Turkey 2007 super heavyweight tournament champion Vitor Miranda, who holds a 24-8 mark with 18 (T)KO victories as a kickboxer. The 34-year-old made his pro debut in 2003, but didn’t undertake his sophomore effort until 2007, when he dropped a decision to UFC veteran Fabio Maldonado. He rebounded with a three-fight winning streak before encountering Maldonado again, this time under the Bitetti Combat banner. Maldonado handed Miranda another decision loss, but the Joinville, Santa Catarina, native recovered with five wins in his next six fights. Miranda has trained at Team Nogueira, Imperial Athletics and the M-13 Gym.
