According to ESPN, O’Sullivan, a Golden Boy signee, is a possible opponent.
One potential replacement opponent is fringe contender Gary “Spike” O’Sullivan (27-2, 19 KOs), 33, of Ireland, who probably was going to fight on May 4 on Golden Boy’s ESPN card in Las Vegas. Whomever Golovkin fights next, a victory would tie him with Bernard Hopkins for the most consecutive middleweight title defenses in boxing history at 20.
