British and European middleweight champion Billy Joe Saunders will fight Chris Eubank Jr on 29 November at London's ExCel Arena.
Saunders, 25, faces Eubank Jr, 24, on the undercard of Tyson Fury's fight against Dereck Chisora.
Frank Warren, Saunders' promoter, told BBC London 94.9 he is expecting a memorable contest.
"They're both undefeated and there's a bit of bad blood between them so it will be a cracking fight," he said.

"The winner will go on and fight for the world title."
Saunders, from a Romany Gypsy community in Hertfordshire, won the vacant European middleweight title with his 20th straight victory against Italian Emanuele Blandamura in Manchester in July.
Eubank Jr, son of former world champion Chris Eubank, extended his unbeaten run to 17 fights with a win over Croatian Ivan Jukic on the same night.
Warren believes both fighters are meeting each other at the right time.
He added: "Eubank's father has been guiding his career and he says a lot of good things about him and in the last couple of fights he's looked extremely good.
"He's put together quite a few stoppages and at this stage of his career he's a better fighter than his father.
"Bill is a great young talent and it's got all the ingredients of a good competitive fight."
