Thiago Santos (heavyweight fighter)

Early career

Santos made his professional MMA debut in October 2007. He fought in a one night tournament against Shamil Abdurahimov at IAFC - Mayor's Cup 2009 and won via unanimous decision. He then went on to fight Oleksiy Oliynyk the same exact day and suffered the first loss of his career.

He then rebounded from that loss by knocking out Geronimo dos Santos in the first round at Amazon Fight 3. After that fight he faced Ubiratan Marinho Lima and won via DQ at Amazon Fight 4.

Bellator

In April 2011, Bellator announced that they have signed Santos and he will make his promotional debut on May 21, 2011 at Bellator 45 against Derrick Lewis. If Santos is victorious then he will earn a spot in the Bellator Season Five Heavyweight Tournament. Santos suffered an undisclosed injury, forcing him out of his Bellator debut.

Santos was originally scheduled to face Blagoi Ivanov in the opening round of the Bellator Season Five Heavyweight Tournament at Bellator 52. Santos, however, was unable to travel from Brazil for the event and was replaced by Zak Jensen.

Santos faced Josh Burns at Bellator 53 in a bout to determine the Heavyweight Tournament reserve fighter. He won the fight via submission in the first round. He was to face Blagoi Ivanov in the semifinal of the tourney on October 29, 2011 at Bellator 56, after Mike Hayes was forced out of the tournament due to injury. Ivanov subsequently had to pull out of the bout due to an injury and was replaced by Neil Grove. Santos won via submission in the first round.

Santos faced Eric Prindle in the finals held at Bellator 59. The bout was ruled a No Contest after Santos kicked Prindle in the groin at 1:24 of the first round and Prindle was unable to continue. The two were scheduled to rematch at Bellator 61 on March 16, 2012. However, on March 15, Bellator announced the fight had been pushed back a week to Bellator 62 due to Prindle having "flu-like symptoms." A week later at the Bellator 62 weigh-ins, Santos weighed in 12 pounds overweight for the rescheduled rematch and the bout was called off. As a result of Santos' inability to make weight, Prindle was announced as the Season Five Heavyweight Tournament Winner.
