Thales Leites Lourenço (Portuguese pronunciation: [ˈtaliʒ ˈlejtʃiʃ]; born September 6, 1981) is a Brazilian mixed martial artist currently competing in the middleweight division of the Ultimate Fighting Championship.
Mixed martial arts 
A relative newcomer to the sport, Leites made his mixed martial arts debut at Shooto Brazil in 2003, defeating Felipe Arinelli by arm-triangle choke submission. Leites would win his next two fights in Vitória before making his debut in the United States in Hawaii's Rumble on the Rock promotion in 2005, where he defeated Adam Roland in his fourth consecutive mixed martial arts victory.
After a successful outing in the U.S., Leites returned to Brazil to fight Gustavo Machado, who was coming off two wins in the Japanese Pancrase organization. Leites defeated the more experienced Machado by submission in the third round, and was invited back to Rumble on the Rock to fight Hawaiian Ronald Jhun in September. Despite fighting a hometown favorite, Leites notched his sixth victory, defeating Jhun by technical knockout in the later half of the fight.
Although Leites held an unblemished record, he did not gain much mainstream exposure until his bouts with Osami Shibuya in Japan's MARS promotion, and Jose Landi-Jons in Brazil's Jungle Fight promotion. In both fights, Leites was much less experienced than his opponents; about Landi-Jons, Leites admitted, "He was already famous when I was not even interested" in mixed martial arts. Despite the experience disparity, Leites defeated both opponents, scoring a unanimous decision over Shibuya, and submitting Landi-Jons with an arm-triangle choke, increasing Leites' professional record to 9-0.
Ultimate Fighting Championship 
In September 2006, it was announced that Leites would make his UFC debut against veteran middleweight Nate Marquardt at Ortiz vs. Shamrock 3: The Final Chapter. However, due to issues with his travel documentation, Leites was not able to compete at the event as planned.
In his next fight, at UFC 69, he defeated The Ultimate Fighter 4 contestant Pete Sell. Leites next earned a submission victory over Floyd Sword at The Ultimate Fighter 5 Finale by arm-triangle choke. He was then scheduled to fight Ryan Jensen at UFC 74. Leites accepted the fight after Travis Lutter, Jensen's original opponent, was forced to withdraw from the event. Leites defeated Jensen by armbar submission in the first round, raising his UFC record to 3 wins, 1 loss.
Leites was scheduled to fight Nate Marquardt at UFC 81, but withdrew from the bout after breaking his hand in training. Leites finally fought Marquardt at UFC 85, winning by a controversial split decision due to point deductions in the 2nd and 3rd rounds to Marquardt.
On the undercard of UFC 90 Leites was able to earn a submission victory over heavy-handed Drew McFedries. This win would prove to be valuable as Leites was able to earn number one contendership to the UFC middleweight title against current champion Anderson Silva on UFC 97 in Montreal. Leites was defeated by Silva via unanimous decision in what is called by many to be the worst fight in MMA history. On his return to the octagon, Leites was defeated again via a controversial split decision against Italian Alessio Sakara. The fight inspired a lot of booing which started during the first round and continued throughout the fight. The lack of action during the fight at one point caused referee Marc Goddard to state to the fighters that Mixed Martial Arts was a "contact sport".
Following the loss, Leites, along with George Roop and Tamdan McCrory, were cut from the UFC. Just days later, Dana White revealed to Yahoo Sports his unawareness of McCrory and Leites' release from the UFC and expressed his intentions to reverse those actions. Shortly after, White decided not to reverse the decisions.
Leites earned a decision victory over Dean Lister at MFC 23 on December 4, 2009, a submission victory over Rico Washington at Bitetti Combat MMA 6 on February 25, 2010, and a submission victory over Jesse Taylor at MFC 25 on May 7, 2010.
In the Superior Challenge promotion, Leites submitted top European Middleweight Tor Troeng at Superior Challenge 6 on October 29, 2010, and fought Jeremy Horn to a split decision victory at Superior Challenge 7 on April 30, 2011.
Personal life 
Leites and his girlfriend had a daughter named Valentina in July 2009.
