WBA middleweight champion Golovkin displayed his power on Saturday evening in stopping Matthew Macklin inside three rounds, which has resulted in Hearn proposing a fight between the Kazakh boxer and IBF and WBA super-middleweight title holder Froch.
Hearn told Sky Sports News: "Golovkin is one of most widely avoided fighters on the planet and fair play to Macklin for stepping up, but Golovkin is a freak of nature. He's a beast.
"According to HBO, he'd be willing to step up to super-middleweight and a fight with Carl Froch would just be epic."
Golovkin has stopped 24 of his 27 opponents in an unbeaten professional career, while Froch has won 31 out of 33 encounters.
