Although we had expected Koki Kameda to be eying up a bout with Narvaez, it now seems his brother is the more like candidate for the Narvaez clash. This would, if it's signed, allow Daiki to delay his mandatory title defense against South African Zolani Tete, however a bout with Narvaez isn't an easy one.
We would assume that Daiki would be easier to pry out of Japan than Koki, who lets be honest doesn't seem likely to travel to Argentina. However what may be the idea is that if Narvaez was to beat Daiki then Koki would get a fight with the Argentinian in Japan with both the IBF and WBO titles on the line.
Of course another reason why Daiki maybe the one being targeted is the fact Daiki doesn't seem to take the easy option like his brother. In 2013 Daiki showed his bottle by fighting against 2 very credible opponents in the form of Rodrigo Guerrero and Liborio Solis, whilst Koki fought 3 less established opponents, and struggled with 2 of them.
We'll not yet be saying this is confirmed but it's a bout that certainly does interest us if it does get made and we'll be hoping that it does, although we'd actually prefer to see a fight between Koki and Narvaez as we'd like to see Koki given a test following his questionable moved to Super Flyweight in late 2013.
