Assuncao narrowly defeated Dillashaw in October 2013 by split decision in a fight that Dillashaw felt that he won. The Brazilian is riding a seven-fight winning streak, but hasn’t competed since October 2014 due to a lingering ankle injury. It will be the first fight for Dillashaw since losing the 135-pound belt in controversial fashion to Dominick Cruz in January.
UFC 200 takes place at T-Mobile Arena in Las Vegas, and is headlined by the light heavyweight title fight between champion Daniel Cormier and interim titleholder Jon Jones. In the co-main event, the interim featherweight title is on the line as former champion Jose Aldo faces Frankie Edgar. Also on the fight card, women’s bantamweight champion Miesha Tate puts her title on the line for the first time against Brazil’s Amanda Nunes.
