Gilbert Burns, commonly known as "Durinho" is a jiu-jitsu black belt under Rafael "Fofitio" while being also regarded as one of his generation's top grappling competitors, a status he held before switching his career focus to mixed martial arts (MMA), a transition that occurred after Burns conquered the International Brazilian Jiu-Jitsu Federation (IBJJF) World title in 2011. A former member of the Oriênte Club and the Atos Academy in the sport of BJJ, Durinho's MMA career started with the help of veteran cage-fighter Vitor Belfort, who Gilbert helped in the capacity of Grappling Coach during the filming of the 2012 reality TV program, The Ultimate Fighter Brazil (TUF) - Belfort vs Silva, later becoming a UFC fighter himself, signing his contract on May 2014.
