The title was vacant and only Yafai was eligible to win it with an eventual win.^[2] Yafai managed to secure the win with a boxing masterclass, winning on all three scorecards.^[3]

In his next fight, he knocked out Luis de la Rosa in the second round to secure the win.^[4]

Next, Concepcion fought unbeaten super flyweight Andrew Moloney. Concepcion lost the fight in the tenth round via TKO. Moloney was dominant from the opening bell, with Concepcion having some success in the latter rounds, but not nearly enough to make a difference in the fight.^[7]
