Golovkin tipped the scales at 159.6 pounds and Alvarez came in at 159.4 at Friday's weigh-in, where the Mexican put his forehead against Golovkin's as they squared up to each other, prompting a brief shoving match on the T-Mobile Arena stage. Of course, given the way one of the most highly-anticipated boxing events in recent memory ended, a rematch was warranted.
And this time it's personal.
But the consequences of Canelo's failed drugs test were enormous for Golovkin, too.
"I don't believe all his stories about contaminated meat", Golovkin said this week.
Luckily for Golovkin, he hasn't had to listen. The two fighters didn't engage in the traditional faceoff after Wednesday's press conference at the MGM Grand.
When they finally do meet Saturday night it will be with some hard feelings on both sides that didn't surface in the first fight.
"Those are the kicks and screams of someone who is drowning", Alvarez said of Golovkin's doping claims. "I want to punish him for all the bad things that he and his team have done".
The rematch initially scheduled for May 5 earlier this year. However, that was scrapped after Canelo failed a drug test for the banned substance, clenbuterol.
A last minute agreement resolved the purse split, with Triple G getting closer to the 50-50 he was demanding.
The official purses were confirmed to ESPN by the Nevada State Athletic Commission, although both fighters are expected to make upwards of tens of millions more after pay-per-view sales.
Now the rematch has to live up to the hype.
"I won the weigh-in, and tomorrow I'll win the fight", he said.
Sanchez has carried much of the burden for the fight's promotion, as both fighters are more comfortable speaking in their native languages than in English. "But I think at the end of the day, there's nothing else Triple-G can do to further polish his apple if he wins this fight".
Golovkin, the unbeaten WBA, WBC and IBO champion, will be chasing a place in boxing history as he attempts to make a record-breaking 21st consecutive defense of his middleweight crowns against Mexican idol Alvarez at a sold-out T-Mobile Arena. I would advise him to retire - I really would. "Every night before bed I visualize what I'm going to do, which is to get a knockout". "Injection marks were evidently there", Golovkin said.
