Two-weight British champion Liam Williams will fight for the WBC Silver middleweight title at the O2, London on Saturday 13 July.
‘The Machine’ will take on former European champion Karim Achour on the night of the heavyweight double header featuring Daniel Dubois v Nathan Gorman and Joe Joyce v Bryant Jennings.
Williams knocked out Joe Mullender in his last bout at the Royal Albert Hall in March.
Frenchman Achour, 32, has won 27 of his 35 fights and never been stopped.
He won the vacant European title in October 2015, forcing Moez Fhima to retire in the tenth round, before claiming the French middleweight title in June 2017.
He then won the WBC International title in February 2018 before suffering a points defeat to big-hitting Canadian David Lemieux.
Williams, 20-2-1, insists he is capable of inflicting a first stoppage on Achour.
It is great for me and a big step up,” said the Welshman. “It is what I have been calling for and it will be another title to add to my collection.
“I am excited, I am sure I am going to win in a good fashion and just keep progressing.
“We tried getting certain opponents which we weren't able to pin down for whatever reason but, for me, I couldn't give a monkeys over whoever I fight for a WBC Silver title. It doesn't matter to me.
“For me it is about picking up the title and taking another step in the right direction towards the ultimate goal, which is obviously becoming world champion," he added, before noting the apparent durability of his forthcoming opposition.
“I just think, with the roll I am on at the moment, I feel like I am going to go through people and I don't think this guy is going to make it through the full fight and is going to get stopped for the first time.”
