Speaking with Sky Sports, Hearn suggested a deal could be struck to bring the British duo together in a rematch that is sure to garner plenty of attention:
I think there's a great chance.
I think it comes down to ego and pride at the end of the day, and of course a lot of money.
As a fan and a promoter it's the biggest fight out there. I know we could have this at a huge stadium and have 60, 70, 80,000 people.
Hearn called the original bout "one of the best fights" he has ever witnessed while also saying, "I think we are going to get there" when clamouring for a rerun.
As reported by Ben Dirs of BBC Sport, Froch won the first battle under controversial circumstances after referee Howard Foster stopped the fight early in the ninth round.
Groves had knocked his more experienced foe down earlier in the contest and was ahead on all three judges' scorecards when the moment arrived, but it appeared as if the 25-year-old Londoner was defending himself from the incoming flurry.
Although Froch is thought to have plenty of options after his win, Groves has continued to bait his rival on social media in the aftermath of the fight. The rapidly improving brawler regularly promotes "#RematchorRetire" on Twitter, as seen here:
Sky Sports reported that Hearn will meet with Froch on Jan. 14 to decide whether or not a second encounter will go ahead.
Froch may wish to face Andre Ward once more in order to overcome the American who beat him in December 2011. Speaking to BBC Radio 5 Live in November of last year (h/t BBC Sport), Ward rightfully confirmed, "Froch needs me more than I need him."
A mouthwatering battle against Gennady Golovkin could also be a possibility, as outlined by Eurosport via Yahoo! Sports.
Hearn previously suggested to Sean Ingle of The Guardian that if Froch vs. Groves II is to happen, it could take place at Wembley:
We have had a number of approaches from football clubs and outdoor stadiums. Don't forget, when Matchroom did Nigel Benn v Chris Eubank II at Old Trafford it sold 45,000. I think Froch v Groves II would be the biggest grossing outdoor boxing event of all time in this country.
While it seems there is plenty to sort out before this rematch becomes reality, Hearn's confidence toward a potential second fight suggests boxing fans could have a particularly tense showdown to watch in the near future.
