Chris Eubank Jr will meet Liam Smith in a mouthwatering domestic clash on January 21 in Manchester.
Eubank had been due to face Conor Benn last month, only for his rival to fail a drugs test, forcing the fight to be postponed.
The 33-year-old has moved on to another all-British clash against former world champion.
Smith is coming off victory over Hassan Mwakinyo in September.
Smith said: ‘He’s making a big mistake fighting me. Every time he has stepped up to elite level, he has failed. I am elite and he will fall again on January 21st in Manchester.
‘If he was at 60 per cent for the fight that never was against Conor Benn, then he’ll need to be at 160 per cent to be ready to face me, a former world champion, in front of thousands of my fans in the North West.
‘For Chris this is a high-risk, low-reward. For me, it’s the perfect platform to show I will rule the world again in 2023. He needs to be prepared for the toughest night of his career.’
BOXXER CEO Ben Shalom said: ‘This is the fight that British boxing fans have been calling for.
‘There aren’t many bigger names in the sport than Chris Eubank Jr, who many believe is coming into his prime now. This is his biggest fight in recent memory against a truly world class fighter Liam Smith. Liam is proven at world level and in the form of his life. Many will feel that he is the favourite going into this.
‘It will be a huge occasion for British boxing and we’re delighted to bring this mouthwatering event to the fans in the iconic fight city of Manchester.’
