The bout, mooted to take place on the undercard of Floyd Mayweather's bout against Marcos Maidana on May 3rd, was thought to be all but signed and sealed but unfortunately things don't seem to be that clear.
Mares, a 3-weight former world champion, seems to have realised that Miura isn't a pushover like he seemed to expect and instead is actually a fearsome fighter who would hold size, strength and power advantages over the Mexican fighter. With that in mind Mares seems likely to back out and leave Miura, AKA "the Japanese Mexecutioner", missing out on what would have been a very high profile contest and a chance to show off his skills to a wider US audience.
Whilst some will say it's a good move from Mares to at least think twice about the bout it is worth noting that the Mexican can't afford to waste much more time. The supposed date of the bout is less than 2 months away and if Mares doesn't want the challenge of Miura he should say so now rather than drag out the whole issue and put the Japanese fighters career on hold.
Thankfully if the bout does fall through then it leaves the door open for a rematch between Miura and WBA champion Takashi Uchiyama in a bout that we actually prefer to see made sooner rather than later. Uchiyama does look to be on the slide and if the rematch has to wait until next year then we don't think it'd be as good a bout as if it was made for the middle of this year.
Whilst both fights are great we just hope Mares makes up his mind rather than drag the whole process out any longer.
