Golden Boy Promotions CEO Oscar De La Hoya, who promotes Mexican superstar Saul "Canelo" Alvarez (49-1-2, 34 KOs), took to social media to bait IBF, IBO, WBA, WBC middleweight champion Gennady Golovkin (38-0-1, 34 KOs).

Canelo and Golovkin fought last September, at the T-Mobile Arena in Las Vegas, and their contest ended in a controversial twelve round split draw.

Earlier this year, it was announced that a rematch was set down for May 5th, also at T-Mobile.

Everything appeared to be on course - until it was revealed in March that Canelo had tested positive for the banned substance clenbuterol - which the boxer attributes to eating contaminated meat during training camp in Mexico.

Eventually, the Nevada State Athletic Commission would crack Canelo with a retroactive six month suspension.

The looming suspension would force Canelo to withdraw from the scheduled rematch.

Golovkin still fought on May 5, when he knocked out late replacement Vanes Martirosyan in two rounds at the StubHub Center in Carson, California.

Canelo's suspension would allow him to fight on September 15th, as part of Mexican Independence Day weekend. 

And now the attention is centered on whether or not a rematch between Canelo and Golovkin will happen in September.

De La Hoya is already starting the verbal barbs - warning Golovkin that Canelo can make a huge pay day with or without the rematch. 

"In the mean time, Golovkin is making 3 million and Canelo is making 40 million without you. Sign the contract, [you're] scared, stop crying," De La Hoya stated on social media.

De La Hoya was likely annoyed, that Golovkin stated in a recent interview that he's only placing a "10 percent" probability on the rematch coming together for the fall - because this time around GGG is not willing to make the bulk of the concessions.

“I would say it’s about a 10 percent probability at this point that it happens,” Golovkin told Yahoo Sports. “I would say only about 10 percent that it happens.”

“I think 10 percent is high; it’s bigger than it should be. I made 99 percent of the concessions for the fight with Canelo on May 5. Ninety-nine percent of them were by me, and now he’s the one not here.”
