@bbc.reporter, yeah this is a mandatory fight for Naoya Inoue as ordered by WBA if i'm not mistaken. As you can see in the picture below, the number 1 spot is vacant while Ramon Cardenas is ranked number 2. One thing i don't like with Team Inoue or maybe Top Rank is that they keep feeding Inoue guys who are not popular that could draw crowd in the stadium.
Because Inoue is their dog. Nery made it possible anyone in this upper division can knockdown Inoue. But once they will mandate Inoue I think he will climb up than fighting the interim champ.
He will add the excitement in 126. This is one more weightclass to Tank Davis who was rumored to be fighting him as Top ranks superfight. Time is running out for this match , they need it to happen. But this will not happen if Cardenas upsets their fight.
