Froch’s team opened negotiations with Gennady Golovkin???s representatives last month over a possible Wembley showdown.
Golovkin, the WBA champion, is running out of opponents in the middleweight division and was willing to step up to 168lbs in order to take on the Nottingham fighter in London.
However, Golovkin’s promoter Tom Loeffler has since admitted talks have stalled and that they are now looking at other opponents, including a unification fight with IBF holder David Lemieux.
Froch, who turns 38 next month, last fought in a domestic rival rematch with George Groves just over a year ago and Hearn admits ‘the Cobra’ may now hang up his gloves.
“I’ve spoken to Golovkin’s manager Tom Loeffler and Carl still hasn’t decided if he’s fighting again yet,” Hearn told ESPN. “If he does fight again, there’s a very good chance it will be against Golovkin but at the moment there’s nothing.
“I think now there’s a strong possibility he will retire. People are saying he has to hurry up and make his mind up, but he will make up his mind when he wants to.
“There’s also the possibility of a big domestic fight against James DeGale for a world title to consider, but my gut feeling is that he will not fight again.
“Boxing fans would love to see him fight again, but if he hasn’t got the desire he definitely shouldn’t get back in the ring again. If he wants to fight again he will, if he doesn’t, what a way to go out last time against Groves in front of 80,000 at Wembley.”
