WBC lineal middleweight Canelo Alvarez is expected to go back in the ring this coming May 7 in Las Vegas though his opponent has yet to be determined.

It will be his voluntary fight before addressing the WBC requirement where the Mexican will have to face mandatory challenger Gennady Golovkin.

For his part, Golovkin will also be in an interim fight this April though his opponent has yet to be named as well.

Whatever happens, the bottom line is that both fighters will have to face each other. However, for the ones who have closely followed the drama between the two fighters, a bit of a controversy exists.

This has something to do with the celebrated catchweight that Alvarez wants in play which could be snag when it comes to negotiations. The issue had died down a bit with the two fighters focusing more on their interim fights.

The latest word, however, from BoxingScene says that Alvarez is standing pat on that requirement which could jeopardize all hope of seeing that big fight in the Fall.

Alvarez is standing pat on fighting at 155 lbs., claiming that he is through when it comes to giving way to make big fights such as this from happening per his interview via ESPN Deportes.

However, the problem is that Alvarez is in a division where his catchweight is a demand, which works only to his advantage. The WBC is unlikely to give in to his request, same as mandatory challenger Golovkin. The Kazakh wants the fight to be made at the full middleweight limit of 160-pounds, which could hamper the fight from prospering.

With that said, there is a possibility that Alvarez could be stripped of the title and eventually make Golovkin the full champion without breaking a sweat. In all, Triple G will become full champion by default.

That development is bad news for the boxing fans who were hoping to see that epic clash between the two big fighters in the middleweight to date.

The closest that the two had, perhaps, come across was a sparring session which took place some years back. Alvarez says that the sparring was pretty good. However, he obviously understands that everything changes when an official fight takes place.

It remains to be seen if something else develops after May. Alvarez could have a change of heart and nix that catchweight rant or, then again, maybe not.

As it stands now, all eyes will be on Alvarez since Golovkin seems to be prepared for anything.
