Hearn previously said Croke Park and Las Vegas bouts would “tick off the list of boxes for Katie Taylor”.
“Hopefully we can tick one of those boxes next, but even at this point I think Katie acknowledges that we’re probably approaching the final chapter.
“She’s given everything to this sport. She is one of the greatest individuals and greatest athletes, not just that Ireland’s ever seen but the world has ever seen.
“I’m very determined to make sure we can deliver all her dreams before she steps away from the sport.”
Hearn was speaking before Saturday night’s card at the SSE Arena with Belfast’s Lewis Crocker taking on Limerick’s Paddy Donovan in the headline bout.
“The atmosphere is very special here,” Hearn added when asked about Belfast’s rich history of boxing.
“If you put an average show on you’ll sell an average amount of tickets but the people here, they know their boxing and when there’s a big event, they’ll come, like they will tomorrow night.
“It is an all-Irish fight and the winner goes on to fight for a world title in the welterweight division, which has huge names like Ryan Garcia, Devin Haney, Teofimo Lopez and Jaron Ennis so this is a golden ticket for whoever can win tomorrow.”
