Chris Eubank Jr has accused Conor Benn of putting a 'black mark' against his family's name ahead of their grudge match on April 26.

Eubank Jr and Benn's fathers, Chris Sr and Nigel, famously fought each other twice in the 1990s, and the family rivalry is set to continue next month at the Tottenham Hotspur Stadium.

But they were due to fight each other in October 2022, only for the domestic dust-up to be cancelled in fight week after Benn failed two drugs tests.

Two-and-a-half years later, they will finally meet in the ring, but Eubank Jr is still angry about Benn testing positive, and believes he has severely tainted his father's legacy. 

An interview with Eubank Jr and Benn was aired on Piers Morgan Uncensored on Friday night, and the latter admitted his dad had struggled to come to terms with the news of his failed tests.

At this point, Eubank Jr interrupted to say: 'His father's upset more than him because he's destroyed his father's legacy. He's put a black mark against the Benn name.'

Nigel was a two-weight world champion, winning 42 of his 48 professional bouts and becoming a household name thanks to his ferocious fighting style.

But Eubank Jr now feels there should be question marks about whether Nigel also 'cheated', as he suggested that Conor may have been following his father's lead.

'The worst thing Conor's done is put question marks against the Benn name, because as they say "like father, like son",' Eubank Jr added.

'So if he's capable of cheating, did his father cheat? That's now the question that arises. I don't believe his father didn't know what he was doing. I just don't believe it. 

'So that means that Nigel Benn could have been capable of doing the same thing in his career. That's the question that has now arisen because of what he did.'

This is not the first time Eubank Jr has hit out at his rival's dad in recent times.

After Eubank Jr smashed an egg into Conor's face at the launch press conference for their fight last month, Nigel grabbed Eubank Jr by the throat.

At a subsequent press conference two days later, Eubank Jr addressed the incident as he sent out a chilling warning to Benn Sr.

'You did put your hand on my neck. I'm going to give you a pass because of what happened,' Eubank Jr said.

'I'm just letting you know that if your hand ever touches me again, you won't get it back.'

That prompted an immediate reaction from Conor who shouted out: 'Shut your f***ing mouth. Threaten my dad again and watch what happens to you.'
