Janigleison Herculano Alves, better known as Gleison Tibau (Portuguese pronunciation: [ɡlejˈsõ tʃiˈbaw]; born July 10, 1983 in Rio Grande do Norte, Brazil) is a Brazilian mixed martial artist currently fighting for the Ultimate Fighting Championship. He is one of the largest lightweights in MMA, weighing up to 185 pounds by the time he enters the cage.
Mixed martial arts 
Tibau began training for mixed martial arts when he was 13 years old and was fighting by the time he was 15. He was a state champion in Rio De Janeiro in both jiu-jitsu and wrestling. He was brought up as a fighter in Kimura team, from the northern part of Brazil. Today Tibau trains at American Top Team. Gleison's biggest strengths are his conditioning, wrestling, size and his Brazilian Jiu-Jitsu.
Ultimate Fighting Championship 
Tibau made his UFC debut at welterweight against Nick Diaz. Tibau started strong and was taking Diaz down efficiently while avoiding submissions using his jiu-jitsu. In the second round he tired and lost by TKO due to strikes.
After the fight, Tibau took on Jason Dent at UFC 68. Tibau dominated the fight and won by unanimous decision. He then took a one fight hiatus from the company and returned defeating Jeff Cox by submission due to an arm triangle choke. Tibau then took on undefeated Brit Terry Etim, outwrestling his opponent and taking a unanimous decision.
Tibau's next fight was set to be against former UFC lightweight champion Sean Sherk at UFC 104. Sherk pulled out of the fight and was replaced by Josh Neer. Tibau defeated Neer after landing a total of 10 takedowns during the fight via unanimous decision (30-27, 30-27, 30-27).
Tibau was expected to face Bart Palaszewski on May 28, 2011 at UFC 130, replacing an injured Cody McKenzie. Palaszewski was also injured and replaced by return UFC veteran Rafaello Oliveira. Tibau defeated Oliveira via second round rear naked choke, earning Submission of the Night honors.
