The two men fought in a WBA title fight in January 2011 and although Miura dropped Uchiyama, hard, he was eventually stopped himself with a badly swollen eye. That was Miura's first world title bout and whilst the loss was painful it did suggest that he had the ability to become a world champion himself one day. Of course since that bout Miura has become the WBC champion and made two impressive defenses of the title with a third expected to come this Saturday against Puerta.
Uchiyama will be hunting his 9th defense of the WBA belt on December 31st when he battles against Israel Hector Enrique Perez (27-2-1, 16). It's thought that if he gets through that and if Miura defeats Puerta then then the talks between the camps will begin in the new year.
In the past the teams have come close to making a deal though one thing or another has come in the way of a rematch. Hopefully this time around nothing will stop the men from getting it on in the ring in a major unification bout, however with both men having bouts before the year is over this isn't even close to being a done deal yet.
