Alvarez and Golovkin get another chance to settle what they couldn't last September when they meet in a rematch of their first fight, which ended in a draw.
Golovkin beat Vanes Martirosyan as a replacement opponent on May 5 at the T-Mobile Arena. They likely won't look into each other's eyes until the opening bell for a sellout crowd Saturday night.
Scores of 114-114 and 115-113 in Golovkin's favour appeared to fairly reflect the narrow margin between the two men - but ringside judge Adelaide Byrd's freaky scorecard, ruling in favour of Canelo by 118-110, left many observers baffled.
Only a freak scorecard from judge Adalaide Byrd, who triggered uproar after ruling it 118-110 Alvarez, denied Golovkin a victory.
The purses for Saturday's PPV undercard fighters are: Jaime Munguia, $250,000; Brandon Cook, $30,000; David Lemieux, $200,000; Gary "Spike" O'Sullivan, $400,000; Roman Gonzalez, $200,000; Moises Fuentes, $35,000. After failing two drug tests in February for clenbuterol and pushing the date from May 5 to September 15, Golovkin and his team have labeled Alvarez as a "cheater" - even though the latter has said on numerous occasions that contaminated meat caused the positive results.

Alvarez was ultimately suspended for six months by the Nevada Athletic Commission.
The 28-year-old vehemently denied any wrongdoing, maintaining he had ingested the drug accidentally as a result of eating contaminated beef from his native Mexico. However, that was scrapped after Canelo failed a drug test for the banned substance, clenbuterol.
"I want to punish him", said Golovkin, 38-0-1 with 34 knockouts.
"He's promised the fans he's going to knock him out but in order to do that you have to be in range and then it gets risky", Sanchez said. "It's kind of disappointing, because I think this is probably going to be the best fight boxing is going to put on this year".
The former Olympic gold medallist is a brutal body puncher, perfecting the technique traditionally associated with Mexican boxing to finish some of the 160lb division's toughest men.
But the youthful Mexican could look to push the pace against his aging rival who, despite having looked as fresh as ever during recent contests, will surely one day show signs of slowing up.
