Briton Fabian Edwards’ rematch with Bellator middleweight champion Johnny Eblen will take place on 19 October in Saudi Arabia.
The bout has been added to the PFL Battle of the Giants event in Riyadh, which is headlined by heavyweights Francis Ngannou and Renan Ferreira.
Edwards, 31, was stopped by American Eblen in the third round of their title fight last September.
The rematch was originally scheduled for the Bellator Champions Series in London last week, but was postponed this month.
Birmingham’s Edwards, who is the younger brother of UFC star Leon, is aiming to become the first English Bellator champion since Liam McGeary in 2015.
Eblen is undefeated, winning all 15 of his fights, and has defended the belt twice since winning it against Gegard Mousasi in 2022.
Former UFC heavyweight champion Ngannou is making his PFL debut at the event after a stint boxing in which the Cameroonian suffered defeats by Britons Tyson Fury and Anthony Joshua.
The 38-year-old is the PFL’s biggest star, with his fight against Brazil’s Ferreira launching the promotion’s new pay-per-view Super Fight Division.
The co-main event features Bellator featherweight champion Cris Cyborg against fellow Brazilian and PFL featherweight title holder Larissa Pacheco.
Elsewhere on the card Paul Hughes, from Northern Ireland, will take on American lightweight and former Bellator featherweight champion, AJ McKee.
