Eubank and Benn will fight at the Tottenham Hotspur Stadium on April 26, but had originally been due to face off in October 2022 before Benn's failed tests forced the fight to be called off.
During a heated exchange in Manchester, Eubank had already made reference to two drugs tests Benn failed in 2022 due to what the World Boxing Council called a "highly-elevated consumption of eggs" - an offence for which he has since been cleared.
It all added to the bad blood between the two fighters, whose fathers Chris Eubank and Nigel Benn twice fought each other during the 1990s and whose rivalry has grown to something that the latter said was "very personal".
Chris Eubank Jr slapped rival Conor Benn with an egg as their personal enmity boiled over in a press conference ahead of their highly-anticipated middleweight clash in April.
Benn promised he would force the 35-year-old Eubank into retirement when the pair meet in a fight that will take place in the latter's division, at 160lbs, rather than at a catchweight.
