WBA super bantamweight champion Guillermo "El Chacal" Rigondeaux (17-0, 11 KOs) is set to face WBA interim titleholder Moises "Chucky" Flores (25-0, 17 KOs).

Rigondeaux vs. Flores is part of the Pay-Per-View undercard to Ward-Kovalev 2: "The Rematch" at the Mandalay Bay Events Center in Las Vegas on Saturday, June 17. The championship event, presented by Corona Extra, will be produced and distributed live by HBO Pay-Per-View® beginning at 9:00 p.m. ET/6:00 p.m. PT.

Rigondeaux was one of the most celebrated amateur boxers in Cuba before defecting and making his professional debut on May 22, 2009 in Miami, Florida. High expectations had no ill effect on Rigondeaux as he tore through his next five opponents. On November 13, 2010, in just his seventh pro fight, Rigondeaux faced Ricardo Cordoba for the vacant interim WBA World Super Bantamweight title and left the ring with the belt after scoring a split decision victory.

Rigondeaux turned his attention to supremacy in the 122-pound division and accomplished what many considered the unthinkable by knocking out WBA World Super Bantamweight Champion Rico Ramos on January 20, 2012, becoming a world champion in fewer than 10 professional bouts.

On April 13, 2013 at Radio City Music Hall in New York City, Rigondeaux scored his biggest victory to date by defeating WBO and Ring Magazine World Champion and 2012 Fighter of the Year Nonito Donaire. Rigondeaux came away with the victory by unanimous decision after out landing and out punching Donaire throughout the fight to unify titles.

In November of 2015, Roc Nation Sports announced that it had signed Rigondeaux to an exclusive promotional agreement and featured him on the HBO Pay-Per-View undercard of the Miguel Cotto vs. Canelo Alvarez mega-fight at the Mandalay Bay Events Center in Las Vegas, where he defeated veteran Drian Francisco via a 10-round unanimous decision.
