Former UFC fighter Darren Till will make his boxing debut against former WBC middleweight champion Julio Cesar Chavez Jr on 20 July.
The bout is on the undercard of Mike Tyson v Jake Paul at AT&T Stadium in Arlington, Texas.
The fight will be over six rounds and at a catchweight of 190lbs.
Till, 31, was released by the UFC in March 2023 after eight years with the promotion.
“I’m very happy with my opponent,” Till said.
“He is a great fighter who I respect, but make no mistake about it, I am coming to knock him out in the first round.”
Till lost his final three fights with the UFC and has been inactive since a defeat against middleweight champion Dricus du Plessis in December 2022.
The Liverpudlian competed at welterweight and middleweight during his time as a mixed martial artist.
