Background and career
Junior dos Santos (Brazilian Portuguese pronunciation: [ˈʒuni.oʁ dus ˈsɐ̃tus]; born 30 January 1984) is a Brazilian mixed martial artist and former professional wrestler who competes in the Heavyweight division. He is a former UFC Heavyweight Champion and current Gamebred Bareknuckle MMA Heavyweight Champion. As a professional wrestler, dos Santos made appearances for All Elite Wrestling (AEW) as a member of the American Top Team stable.
Dos Santos and his two siblings were raised by a single mother, Maria, after his alcoholic father, Sebastian, left the family in the mid-1990s. He started to work at the age of ten in order to help his family. He trained in capoeira throughout his teenage years before he began taking martial arts seriously at 21, when he began training in Brazilian jiu-jitsu under Yuri Carlton. After six months of training, Dos Santos won a few jiu-jitsu tournaments in Salvador. One year later, Dos Santos was invited to join a boxing practice by a friend, where he met his boxing coach Luiz Carlos Dórea. Dórea also trained mixed martial arts, and roughly a year after he started training in boxing, he had his debut professional fight.
Dos Santos turned professional in 2006, at the age of 22. He fought in small promotions in Brazil, such as Demo Fight, Extreme Fighting Championship, Minotauro Fights and Mo Team League. He won six of his first seven bouts, suffering his only loss to Joaquim Ferreira, a fighter he had previously beaten.
Dos Santos debuted for the UFC on 25 October 2008 at UFC 90. Considered a major underdog, he knocked out top contender Fabricio Werdum at a minute and twenty seconds of the first round, earning himself a "Knockout of the Year" award. Returning on 21 February 2009 at UFC 95 he fought promotional newcomer Stefan Struve, defeating him at fifty-four seconds of the first round by knockout. On 19 September 2009, Dos Santos continued his winning streak and defeated Mirko Cro Cop at UFC 103. During the third round Dos Santos dominated Cro Cop in the clinch with knee strikes and punches. A knee from the clinch and a right uppercut apparently caused damage to Mirko's left eye, causing him to submit verbally. UFC 108 scheduled a fight between Dos Santos and Gabriel Gonzaga. However, Gonzaga pulled out of the bout on 25 November 2009 due to a staph infection. Instead, on 2 January 2010, Dos Santos fought Gilbert Yvel, winning the fight via TKO at two minutes and seven seconds of the first round. Dos Santos faced Gabriel Gonzaga on 21 March 2010 at UFC Live: Vera vs. Jones. He won the fight via knockout in the first round, earning him his second "Knockout of the Night" award.
Dos Santos faced Roy Nelson on 7 August 2010, at UFC 117. The fight saw Dos Santos use a variety of strikes and, for the first time, a successful takedown. Despite Dos Santos's striking ability, Nelson was able to stay in the fight, resulting in the fight going to decision. Dos Santos won the fight via unanimous decision. Following the win, there was speculation that Dos Santos would challenge Cain Velasquez for the heavyweight title. However, a torn rotator cuff suffered by Velasquez side-lined the champion for nearly a year.
On 11 January 2011, the president of the UFC, Dana White, announced that Dos Santos would be one of the coaches of The Ultimate Fighter Season 13, opposite Brock Lesnar. They were scheduled to face each other on 11 June 2011, at UFC 131, but Lesnar pulled out of the bout due to a recurrence of diverticulitis and was replaced by Shane Carwin. Dos Santos dominated Carwin and won the fight via unanimous decision, relying predominantly on his boxing skills, but showed more variety in his game by landing a couple of kicks and completing two takedowns in the third round.
