Las Vegas hosts the superstar boxers after Golovkin weighed in slightly heavier on Friday with promoter Hearn tipping the Kazakh to “explode” in the ring.

“This is going to be an absolute all-out war. Gennadiy Golovkin, in his eyes, stone gold, ripped to shreds at 168 pounds, looked so good,” said Eddie Hearn on the DAZN Boxing Show.

“The last couple of fights, you see the cheekbones a little bit more at 160lbs. I’m telling you, this guy is ready for battle. And Canelo, you saw the shadow boxing after that. He’s ready to explode. This is going to be epic.”

Golovkin, 40, was defeated in his second contest with Canelo in 2018 after a draw a year earlier, while 32-year-old Canelo has lost some of his aura since losing to Dmitry Bivol in May.

“Don’t forget; this guy has boxed Canelo Alvarez for 24 rounds,” he added. “It’s not like we’re watching a fight, and we’re going, ‘Oh, I wonder if this guy is good enough to compete with him?’.

“A lot of people thought he won the first fight, and the second fight was razor-thin as well. This is going to be the same kind of fight. Canelo Alvarez, from the first bell, is going to be trying to knock Gennadiy Golovkin out.

“He may be reckless, he may be emotional, and if he is, Gennadiy Golovkin is going to be right in front of him, unloading his artillery on Canelo Alvarez as well. Honestly, back and forth, this is going to be absolutely brutal.”
