The world should finally receive a decisive answer to the question of who is the better boxer when unified middleweight champion Gennady "GGG" Golovkin (38-0-1, 34 KOs) and Canelo Alvarez (49-1-2, 34 KOs) square off in Las Vegas. The rematch will arguably be the fight of the year, and it's one that has been anticipated for quite some time considering the short but intense history between the two fighters.

Floyd Mayweather made a solid attempt to steal some of the headlines away from Canelo and Oscar De La Hoya early Saturday morning by announcing he was going to make a rematch against Manny Pacquiao, but Alvarez and Golovkin squaring off in Las Vegas is expected to be the best matchup of 2018 and one that is still dominating headlines on Saturday.

Alvarez and Golovkin fought to a controversial split decision back in 2017, and they were planning to fight again in May only for that bout to ultimately be delayed. Alvarez was suspended six months and not cleared to fight after the Mexican power puncher failed two steroid tests that he claimed were triggered by the inadvertent ingestion of tainted meat. In the meantime, Golovkin brutalized Vanes Martirosyan on that May date, setting the stage for Saturday's fight.

Not only are Golvokin's unified WBA (super), WBC and WBO middleweight titles on the line, he and Alvarez will be fighting for the vacant Ring and lineal middleweight titles. With so much going down ahead of the fight, let's take a look at everything you need to know before Canelo and GGG meet inside the squared circle in Las Vegas.
