The Nevada State Athletic Commission voted unanimously during a Monday morning meeting to change the result of the Guillermo Rigondeaux-Moises Flores fight to a no-contest.

Rigondeaux originally was declared a winner by first-round knockout June 17 at Mandalay Bay Events Center in Las Vegas. The NSAC changed the result to a no-contest because video and audio evidence proved Rigondeaux's fight-ending left hand clearly landed after the bell sounded to end the first round.

The NSAC also agreed with referee Vic Drakulich's assessment in his post-fight report that Rigondeaux's late punch was unintentional. That's why the result was not changed to a disqualification victory for Flores, who said he couldn't continue after Rigondeaux's punch landed.

Miami's Rigondeaux (17-0, 11 KOs, 1 NC), a two-time Olympic gold medalist for Cuba, will retain the WBA super bantamweight title. Mexico's Flores, who entered the fight as the WBA's interim champion at 122 pounds and was the mandatory challenger for Rigondeaux's title, will remain undefeated (25-0, 17 KOs, 2 NC).

The WBA likely will order a rematch.

The contents of Drakulich's report were not made available during the NSAC's meeting.

According to Bob Bennett, the executive director of the NSAC, the result wasn't changed following an immediate replay review because an unidentified truck technician informed him that Rigondeaux's punch landed before the bell. Flores also appeared to throw a right hand after the bell sounded, but before Rigondeaux's left hand.

Drakulich was more concerned immediately after the fight ended about Rigondeaux holding Flores behind his head and punching Flores prior to throwing that late left hand. Drakulich, who said he didn't hear the bell, did not have a full complement of video and audio available to him when he reviewed video at ringside following the fight.

The Rigondeaux-Flores fight was part of the HBO Pay-Per-View undercard prior to Andre Ward's eighth-round technical knockout victory over Sergey Kovalev in their light heavyweight championship rematch.
