Professional Fighters League’s most accomplished man and woman will both be in action for its third event of the 2021 season.

Fabricio Werdum, the former UFC heavyweight champion who signed on as a free agent last November, will make his debut with the organization at PFL 3 on May 6 against Renan Ferreira in the evening’s headliner. In the co-main event, Kayla Harrison begins the defense of her 2019 women’s lightweight season championship against Mariana Morais.

The full regular season slate will be held at Ocean Casino Resort in Atlantic City, N.J., with the PFL 3 four-bout main card airing on ESPN2 following six scheduled preliminary bouts on ESPN+.

Werdum (24-9-1, 18 finishes) arrives with PFL following a 4-3 run since losing his championship to current UFC heavyweight titleholder Stipe Miocic in May 2016. The decorated 43-year-old grappling wiz won his final bout in the octagon, a first-round armbar submission of former three-time UFC light heavyweight title challenger Alexander Gustafsson, last July 26.

Ferreira (6-2, six finishes), 31, stands 6-foot-8 and will also make his PFL debut.
