The smart guess is that there was problems regarding money with the reported $500,000 figure for Rigondeaux being a huge amount for the promoter to put up for the Cuban fighter, even more so when the bout was unlikely to be a world title bout and was not likely to headline a card. TV money and ticket sales would have covered some of that but it would have been highly unlikely for the promoter to have actually made money on the show when you consider the need for an under-card and the lack of big name notability of Amagasa.
Of course we may again be jumping the queue in reporting this but it is worth noting that there has been no word from the Japanese media about the bout and nothing regarding a press conference or even a ticket listing. It's fair to say however that Tuesday's press conference,which we suspect is to announce Takayama Vs Odaira, is one final opportunity for the bout to be announced
We're very sorry for those who feel let down by this news. We're sure the full story will come out shortly though it certainly doesn't look good for those hoping to see Rigondeaux in the ring again this year. Fingers crossed that we're wrong, and it has happened in the past, but this bout is becoming less and less likely by the day.
