The starting gun for the race to become Britain's next world heavyweight champion will be fired on the banks of the Thames on Saturday.
Daniel Dubois, who hails from London
, and Nathan Gorman, the traveller from Nantwich, clash in the most significant British heavyweight title fight for years.
In the preceding bout at the O2, another Londoner, Olympic silver medallist Joe Joyce, hopes to steal a march on the pair of them by thumping veteran American Bryant Jennings deeper into decline
Tyson Fury, Deontay Wilder, Anthony Joshua and now Andy Ruiz Jr had better get a move on with regard to fighting each other for the undisputed world title.
While Joyce is eyeing a route to the summit via European titles, Dubois and Gorman are taking direct aim at the household names who have been for the most part flirting rather than fighting each other.
Dubois, who looks every muscular inch as powerful as he punches, puts Fury, Joshua and Wilder on notice as he says: 'The heavyweight division now needs a dominant fighter to come through and take over. To become the one we look up to as 'The Man.' I can be that guy.'
Although still 21 and coming into just his eleventh fight, he adds: ' I feel I am only another fight or two away from challenging for the world title - and winning it.'
Gorman, thankful that his new daughter was born early on Tuesday so he can concentrate on Dubois, says: 'Daniel and I sparred a lot as amateurs and I believe I won every round. After this fight, I feel I will be ready for any of the big guns.'
Wilder and Fury have put the rematch for their respective WBC and lineal world titles on hold as they take yet another warm-up fight apiece this autumn. Joshua is still in negotiation over the date and venue for his shot at regaining the WBA, IBF, WBO and IBO belts he lost to that huge upset by Ruiz in New York last month.
Dubois runs the rule over them, saying: 'Wilder has something the others don't really have these days - one-punch knock-out power. He weighs only about 15 stone but he is putting away 20-stone guys like Tyson to prove that it's not all about size.
'Ruiz could have an easier night against AJ second time. Joshua has enough money not to need to fight any more so now we will see what really drives him. Time to show what he has deep down. Although frankly I don't care if he gets his titles back. He has his own career, reached the top and got knocked off his pedestal. It happens, Plenty get knocked off. Even Mike Tyson.'
With the public growing increasingly frustrated by the delays in the big names fighting each other, the opportunity is there for a young gun to burst through.
Promoter Frank Warren, sensing that opportunity, was opposed to one of Dubois or Gorman putting the other out of the picture this early in their careers.
But when both insisted on answering the Board of Control's invitation to box for the vacant British crown he acceded, saying: 'This would have been an even bigger fight next year but they are both so good that while the winner is likely to be first for a world title shot, the loser will come again.'
Both are undefeated. Dubois, having stopped 10 of his 11 opponents thus far, predicts he will prevail by knock-out. Gorman slightly the elder at 23 and having been taken the distance five times in his 16 professional outings, believes that the extra experience gained not only from additional fights but also a higher number of rounds boxed will count in his favour. Especially if it goes the 12-round distance.
The contrast of styles between the KO merchant and the Fury-esque mover should make for a minor classic.
Who wins, thereby staking first claim to the future of the heavyweight division?
One sledge-hammer American legend who tasted the venom in Mike Tyson's fists says: 'Dubois looks to me to have what it takes to go all the way. He has that vital ingredient for becoming a proper world heavyweight champion. Knock-out power.' Who am I to argue with Big George Foreman? Dubois in eight.
