The rematch is sold out, but a lackluster promotion might make it more hard to sell as many pay-per-views as the two fighters did when they first met.
The controversy didn't die down with the disputed decision - the original date for rematch had to be reworked because Saul failed a PED test, his reasoning: it must have passed through his system courtesy tainted meat he'd eaten in his native Mexico. "Saturday night, there will be no escape".
Whether that translates into a more entertaining fight remains to be seen. The 160-pound titles are at stake once again as the two fighters try to settle what they couldn't in last September's draw.
Eventually, to the delight of fight fans around the world, the two parties came together for a third time on a deal that will see the duo go to war for the WBA and WBC middleweight world titles, nearly a year to the day since their first meeting.
Golovkin (38-0-1, 34 knockouts) is a slight favorite in the rematch, much as he was in the first fight.
The bad blood between the pair has grown since Alvarez was temporarily suspended by the Nevada State Athletic Commission in April for testing positive for the banned substance clenbuterol, forcing a postponement of their planned May 5 rematch.
Despite two judges scoring the fight extremely closely - 114-114 and 113-115 in favour of Golovkin - judge Adalaide Byrd's scorecard of 118-110 in favour of Alvarez had many fans and pundits alike questioning the validity and reliability of the adjudicating.
In the hours leading up to the first fight, a late flurry of money on Golovkin drove his odds to -200 before the bell sounded.

Gennady Golovkin is a solid favorite in his rematch with Canelo Alvarez on Saturday in Las Vegas, but the bulk of the early action at sportsbooks, including some of the largest bets, have been on the underdog.
Alvarez (49-1-2, 34 knockouts) believes that, too, but sees a different result. "But I'm going in there to knock him out".
"If Canelo gives me a chance and fights like he claims he will, I will knock him out", Golovkin said.
Triple G's trainer Abel Sanchez also added fuel to the fire after their first bout by accusing both Canelo and his team of wrapping their fighter's hand in an illegal manner.
"If he intends to knock out Golovkin, he's going to have to fight him", Sanchez said.
Now, after a manic and frenetic weigh-in on Friday night, it appears some of those words and emotions may just have bubbled over slightly, with both fighters being pictured exchanging words with one another as they went face-to-face for the final time before the fight.
