Jacobs was declared the winner via split decision in a fight close enough for ring announcer Jeremiah Gallegos to initially imply that Rosado had been ruled the winner, before correcting his monumental gaffe in what Hearn branded the highlight of the fight.

A few days after the card, Hearn joined the Ak & Barak Show on DAZN to go into further detail on his criticism, and maintained that things remain good between he and Jacobs (37-3, 30 KOs).

"Jacobs-Rosado was a disappointment, plain and simple," admitted Hearn. "These guys talked up the fight and everybody was excited for it, and we got a poor fight. 

"And I know Gabe was saying after the fight ‘yeah I outboxed him’, but in the last few rounds I don’t think Danny was really doing anything at all. Gabe should have been pushing the action and trying to win the fight. Danny, like he said, between that and the atmosphere, it felt more like a sparring session and that’s not what we want to hear.

"Great fighters can’t always gel, but I was disappointed. I thought after all the talk we’d get a real humdinger and it ended up being an average fight. It could have gone either way. More force was thrown by Danny but Gabe outboxed him at times as well."

Hearn then went on to add: "I was disappointed in the fight but this is not like the Bud-Top Rank situation.

"This is not an attack on Danny Jacobs. I value him very highly and I class him as a friend. This is someone who had faith in me when I first started promoting in the States and he was my first signing over here. 

"I’d love to work with Jacobs in the future, I just felt he let himself down on this night. And I felt Gabe did, as well. It happens. That’s not me having a pop at Daniel Jacobs, I just thought he could have done more. He’s still an amazing fighter and there’s a great future out there for him.

"We took a lot of heat for making that fight, so I wanted to make a great fight. We believed in the fight and we believed in the hype, and we battled to get it put on.

"Pacquiao vs Mayweather was a let-down. And it happens. All you can do is put it together. It’s not like there was a global demand for it, but I thought it would be a good fight.

"I love Danny, he’s a great fighter but it was a poor performance and he would say the same thing."

Hearn also confirmed that the win over Rosado was the last on Jacobs' current Matchroom USA deal, but that he intends to negotiate an extention with the American.

"I don’t think it’s the last time we will work together," said Hearn. "There are plenty of options there for him so we will be talking to them about the next steps and we want to keep him as part of the team.

"I feel like he has a big future in the sport. He’s still a top fighter and can win a world title; it’s just not as clear cut [as we hoped]."

Talk inevitably moved to the mistake made by Gallegos, which went viral on social media.

Gallegos, observing boxing tradition when the three ringside judges are split between the two competitors, announced a scorecard for Jacobs and a scorecard for Rosado before drawing out the third and final score, leaving the name of the winning boxer to the very end.

However, instead of concluding the suspense with "from Brooklyn, New York...", Gallegos announced Rosado's hometown of Philadelphia, making everyone watching believe the fight had gone his way.

Moments later, a red-faced Gallegos corrected his mistake and confirmed that Jacobs, not Rosado, had won on the deciding judge's scorecard.

Hearn admitted that he was going to fire the MC for the botch, but has since reconsidered any harsh action.

"He really did Gabe dirty, didn’t he, by botching the decision announcement," Hearn said. 

"I’m a bit of a softy, because my initial reaction was that he’s got to go. And then he put a post out on Instagram and it kind of played on my heartstrings. He said ‘everyone makes mistakes but I made a catastrophic error’, and he really apologised to everyone.

"Listen, with everything going on in the world right now, there are worse things that can happen. So you will see Jeremiah back on another Matchroom show, for sure. It just might not be until 2030. That was a joke, by the way!"
