Unfortunately things don't look like they will be getting any better any time soon for the brothers.
The JBC may have technically jumped the gun by unlisting Daiki Kameda, pictured, from their roster of active world champions though it does appear that they may end up being correct and Daiki, whilst he is still recognised by the IBF as their Super Flyweight champion, he may not keep that recognition for long.
The IBF website currently states Daiki has a mandatory obligation to fulfil by March 3rd 2014. With Zolani Tete having won an IBF eliminator last November Tete would be the mandatory challenger. This would seem to suggest that Kameda has until March 3rd to defend his belt against Tete. That's less than 4 weeks away.
Of course, as we all know by now, Daiki kept his title despite losing to Liborio Solis due to the fact Solis failed to make weight. The IBF rules dictate that if a challenger fails to make weight the champion cannot lose their title.
Although the IBF rules don't explicitly state a fighter will be stripped for failing to meet a mandatory obligation, instead stating that the "Championships Committee and Board of Directors consider withdrawing recognition of the title", it would seem hard for the IBF to stand by Daiki any longer, especially considering the serious backlash the organisation has had in Japan which has reflected very badly on the IBF.
We have asked the IBF to confirm whether or not Daiki will have to meet the March 3rd date though have yet to hear back from them. We would assume they are looking in to the matter though we would not be shocked if the decision was made to strip the Japanese fighter.
