Mexican superstar Canelo Alvarez (49-1-2, 34 KOs) is gearing up for a real brawl with WBC/WBA/IBO middleweight world champion Gennady "GGG" Golovkin (38-0-1, 34 KOs).

The contest takes place on September 15th at T-Mobile Arena in Las Vegas.

Their first bout took place in September 2017, and ended in a controversial twelve round split draw. The rematch will be produced and distributed live by HBO Pay-Per-View beginning at 8:00 p.m. ET/5:00 p.m. PT.

Golovkin, who won an Olympic silver medal, built an impressive 23-fight knockout streak, but then both of his bouts in 2017 went the distance, with Daniel Jacobs and Canelo.

Golovkin was set to face Canelo in a rematch on May 5th - but the contest fell apart when the Mexican star tested positive for the banned substance clenbuterol.

Canelo was then suspended for a six month period by the Nevada State Athletic Commission.

Golovkin still went forward with the May date, and scored a second-round knockout victory against Vanes Martirosyanin.

Following that fight, the negotiations began to finalize the rematch with Golovkin. The discussions played out for several weeks before they reached an agreement on the monetary terms.

From the moment Canelo failed a pair of drug tests, Golovkin verbally slammed him. He accused Canelo of being a drugs cheat - and questioned whether or not Canelo was clean for their initial bout. 

Canelo, who claims the positive tests were a direct result of eating tainted meat, has promised to punish Golovkin in the ring.

"The truth is that this fight means a lot to me because of all that has happened and all that has been said," said Canelo.

"I will prove with my fists that I am the best, and Golovkin will eat all of his words and speculations. I will demonstrate who is the best when I defeat Golovkin soundly on September 15 during Independence Day Weekend, and I'll make it clear that Mexican boxing is the best."
