The fight is a rematch from a fight in September 2017 that ended with a controversial draw.

A fight that had to happen after the disputed draw in the first bout nearly didn't come to be after Alvarez tested positive for clenbuterol just before beginning training for what was supposed to be a May rematch.
Only a freak scorecard from judge Adalaide Byrd, who triggered uproar after ruling it 118-110 Alvarez, denied Golovkin a victory. "I would expect quite a few large bets Saturday".
A rematch between Canelo and Golovkin was subsequently agreed that would have seen the two foes face off on May 5th in a fight perfectly poised to light up boxing's fabled Cinco de Mayo weekend. At the same time it produced some hard feelings between the two fighters over Alvarez's contention that it was caused by eating contaminated meat in his native Mexico.
Members of both entourages quickly got between the two fighters to head off a physical confrontation after Alvarez appeared to rush towards Golovkin, who didn't flinch. "He would have got knocked out the first time, but he decided to make it a track meet".
Gennady "GGG" Golovkin and Saul "Canelo" Alvarez both had to be restrained by their camps after facing off ahead of their long-awaited rematch.
Whilst the selection of judges remained a hot topic during the negotiations for the rematch, both fighters have promised the scorecards won't be needed this time around, with both looking to cement their status as the world's best with a fearsome knockout. Golovkin weighed 159.6 pounds and Alvarez weighed 159.4.
"And if he fights him, he's going to get knocked out".
"If Canelo gives me a chance and fights like he claims he will, I will knock him out", Golovkin said. "It's a real fight, a real war".

"I'm going to go in there to knock him out", Alvarez said.
"I think this fight could be it".
