Canelo Alvarez isn’t playing any weight games regarding weight gains in his showdown with Gennady Golovkin.

Oscar De La Hoya confirmed during an interview Tuesday on ESPN’s “First Take” that the contracted weight limit for their long-awaited fight is the middleweight limit of 160 pounds. De La Hoya, Alvarez’s promoter, also said there aren’t any rehydration clauses in the contracts that would limit either fighter from gain a specific amount of pounds following an official weigh-in September 15.

“My man, let’s just say this is a real, true middleweight fight at 160 pounds,” De La Hoya told ESPN’s Stephen A. Smith and Max Kellerman. “Both guys will fight in 10-ounce gloves. You know, there’s no rehydration, weight-class clause and all this B.S. and this and that. It’s a true middleweight fight, at 160 pounds. And that’s it.”

Alvarez’s two previous middleweight title fights were contested at contracted catch weights of 155 pounds, five full pounds beneath the middleweight limit. He won those two bouts against Puerto Rico’s Miguel Cotto (40-5, 33 KOs), a 12-round unanimous-decision victory in November 2015, and Amir Khan (31-4, 19 KOs), a sixth-round knockout in May 2016.

The Mexican superstar and De La Hoya had mentioned at times last year that Golovkin would have to come down from the 160-pound limit and meet him at a catch weight. Alvarez later said he would challenge Golovkin at the middleweight limit and ultimately kept his word.

The 35-year-old Golovkin (37-0, 33 KOs) has been a middleweight throughout a professional career that began in May 2006. The least the Kazakhstan native has weighed for a professional fight is 158½ pounds for a first-round knockout of Lajuan Simon in December 2011.

The 26-year-old Alvarez (49-1-1, 34 KOs) has boxed above 155 pounds just once in his 11½-year pro career. That thorough win took place Saturday night, when he dominated countryman Julio Cesar Chavez Jr. (50-3-1, 32 KOs, 1 NC) in a 12-round fight at T-Mobile Arena in Las Vegas.

The Alvarez-Chavez bout was contracted for a maximum catch weight of 164½ pounds. That was the lowest Chavez needed to weigh since he lost to Sergio Martinez in a WBC middleweight title fight in September 2012 at UNLV’s Thomas & Mack Center.

According to his trainer, Abel Sanchez, the 5-feet-10 Golovkin usually doesn’t add more than 10 pounds between the time he weighs in and the time his fights start.

Alvarez is believed to have entered the ring at more than 170 pounds for some of his junior middleweight and “middleweight” bouts. The WBO super welterweight champion wouldn’t allow HBO to weigh him on the network’s unofficial scale Saturday night and hasn’t divulged how much he weighed when he got in the ring to face Chavez.
