Renan Barao (Esther Lin/MMA Fighting)Renan Barão vs. Mitch Gagnon Set to Meet in Co-Main Event of UFC Fight Night 58 José Youngs October 16, 2014 News, Spotlight On Wednesday night, the UFC announced a bantamweight matchup between former 135-pound kingpin Renan Barão and the surging Mitch Gagnon has officially been added to UFC Fight Night 58 in December. Barão (32-2) has not stepped foot inside the octagon since fans saw him on the receiving end of one most stunning upsets in mixed martial arts history at the hands of current champion T.J. Dillashaw in their title fight at UFC 173 in May. Heading into this bout, the former champion was riding an incredible 33-fight unbeaten streak, which included seven straight under the UFC banner and three straight UFC title defenses. But Dillashaw shocked the world and systematically dismantled the former champion for four straight rounds before finally putting him away with a violent knockout early in the final frame. Almost immediately, the two were booked to rematch in the main event of UFC 177 in August. However, in one of the most bizarre series of events in UFC history, Barão pulled out of the bout just hours before the scheduled weigh-ins. It was later revealed he was taken to the hospital after he lost consciousness and hit his head while cutting weight in the sauna. The UFC would end up replacing the Barão with promotional newcomer Joe Soto, who would go on to suffer a violent fifth round knockout to Dillashaw. His opponent Gagnon (12-2) will enter this bout riding a four-fight win streak. In his most recent outing, the Ontario native walked away with an impressive first round submission victory over Roman Salazar at UFC Fight Night 54 earlier this month. He will enter this bout with a UFC record of 4-1, with three of those victories ending by way of first round submission. UFC Fight Night 58 is set to take place on Dec. 20 at the Ginásio José Corrêa in Brazil. A middleweight matchup between Arizona native C.B. Dollaway and former UFC light heavyweight champion turned middleweight contender Lyoto Machida will serve as the night’s main event.
