On Tuesday, middleweight champion Gennady Golovkin fired off an arsenal of verbal jabs in the direction of Canelo Alvarez, the Mexican superstar's promoter Oscar De La Hoya, and even the Nevada State Athletic Commission.
Golovkin accused Canelo of being a longtime user of performance enhancing drugs. He rejected Canelo's explanation for failing two tests back in February, which came up positive for banned substance clenbuterol.
The undefeated puncher does not believe Canelo came up positive due to contaminated meat, which is what the Mexican boxer and his team are claiming.
He shockingly claimed that he immediately knew Canelo was "not a clean fighter" following their first encounter.
As far as the Nevada Commission, Golovkin made several allegations that Canelo receivers preferential treatment in Las Vegas - which he feels is evident by their controversial split draw last September and he also feels the NSAC is being very relaxed with respect to Canelo's two positive tests.
"I don't think I would have had the same amount of benefits he has had," Golovkin said. "That's why I would never use any drugs because I know there won't be any preferences to me.
"I felt like I won the fight. I thought I didn't understand something but then I reviewed the fight. These people are like terrorists. They're killing sport. It's not about me. People like that should be in prison. People being cheated like that. It's too much. This is America. This is democracy."
Golovkin is backed by his trainer, Abel Sanchez, who also believes Canelo is given special treatment in Las Vegas.
"Going to Vegas we are two points down and we are gonna need to win more convincingly or to knock him out," Sanchez said.
Bob Bennett, the executive director of the NSAC, reacted to Golovkin's accusations when speak with the Los Angeles Times.
"There were no adverse analytical findings concerning performance-enhancing drugs or any other illegal substance [in Canelo's system for the first]. There are no instances since I've been at the helm where there was any prejudice, bias or favoritism toward anybody," Bennett said.
"We are strictly regulators. We have no interest in who wins or loses as long as the playing field is level."
The NSAC is still investigating the matter and plan to issue a ruling soon - although everyone expects the rematch to move forward as scheduled.
An interesting note from the LA Times, was regarding the original statement from Dr. Daniel Eichner, an expert at the World Anti-Doping Agency lab, which analyzed Canelo's samples.
Eichner was quoted in a statement from Canelo's promoter, Golden Boy Promotions, saying the level was consistent with meat contamination.
However, the paper states that a second quote from the doctor was "chopped" from Golden Boy's official statement.
Eichner had added, "Further investigation is needed to make a final determination" - which the paper states is because "Canelo's Feb. 17 positive sample contained such a higher level than the positive sample collected on Feb. 20."
