Valdez cemented his status as one of the faces of Mexican boxing with his 10th-round knockout over longtime champion Berchelt. He is 8-0 in world title fights, including six defenses of the WBO featherweight world title he won in July 2016. Valdez and Conceição fought as amateurs in the gold medal match of the 2009 Pan American Games, with Conceição prevailing by a single point. Valdez turned pro nearly four years before Conceição (16-0, 8 KOs), who made history as the first Brazilian boxer to capture Olympic gold. A native of Bahia, Conceição made his pro debut in November 2016 on the Manny Pacquiao-Jessie Vargas undercard and knocked out four of his first five foes. Last October, he survived an early knockdown to edge Louie Coria by unanimous decision. He last fought April 10 in Tulsa and knocked out Jesus Antonio Ahumada in the seventh round.
