Irishman Paul Hughes will fight American AJ McKee in Saudi Arabia on 19 October.
The lightweight bout features on the undercard of the PFL’s Battle of the Giants event in Riyadh, which is headlined by heavyweight pair Francis Ngannou and Renan Ferreira.
Former Cage Warriors featherweight champion Hughes, 27, joined the PFL earlier this year before beating American Bobby King on his debut in June to extend his record to 12 wins and one defeat.
McKee, meanwhile, is a former Bellator featherweight title holder, with the 29-year-old winning 22 of his 23 professional bouts.
Ex-UFC heavyweight champion Ngannou is making his PFL debut after a stint boxing which saw the Cameroonian suffer defeats by Britons Tyson Fury and Anthony Joshua.
