By Dan Ambrose: The Nevada State Athletic Commission has reportedly rejected the 21-year-old junior middleweight contender Jaime Munguia (28-0, 24 KOs) as the replacement opponent for IBF/IBO/WBA/WBC middleweight champion Gennady ‘GGG’ Golovkin (37-0-1, 33 KOs) to fight on May 5th, which means Gary ‘Spike’ O’Sullivan (27-2, 19 KOs) is back in the picture once again as the leading candidate to get the fight.
