Eddie Hearn believes that Conor Benn and Chris Eubank Jr.'s bout effectively captures lightning in a bottle , describing their long-awaited grudge match as a "one-off".
The pair will seek to settle their grudges on April 26 when the headline The Ring's Fatal Fury: City of the Wolves at Tottenham Hotspur Stadium, live on DAZN .
An explosive press event on Tuesday saw Eubank Jr. smash an egg against his rival's face and as they follow in the footsteps of fathers Chris Eubank Sr. and Nigel Benn.
The latter duo fought two famed bouts three decades ago, and Hearn believes that the chance to settle family legacy feeds into a story the sport has never seen on this scale.
"This fight is just a massive showcase and spectacle for British boxing," he told DAZN . "It's a one-off. You could never have a narrative like this fight.

"When are you going to get a situation where the greatest rivalry in British boxing ever is re-lit and reignited by those fighters' sons? And at a world level as well?
"In front of 70,000 people, with all the narrative, with all the history, with all the controversy, with all the build-up, with all the rivalry, with all the hatred. There's nothing like it.
"That's why this fight, in my mind, sits as the biggest fight in British boxing. The right time was two years ago, and we know what happened. It's been a horrendous journey.
"But it has been a journey that's only made the fire burn stronger, and only made the fight bigger. It's only intensified the rivalry and made it more intriguing.
"It's spun the narrative like a washing machine, and just spat it out like a tornado. On that night at Tottenham, there will only be one thing and that is fireworks."
