Season Description Two-time Olympic gold medalist and top pound-for-pound women's boxer Claressa Shields signed a three-year contract with the Professional Fighters League to compete in the Women's Lightweight division and former UFC lightweight champ Anthony Pettis who joined the Professional Fighters League ahead of the 2021 regular season.
PFL's 2021 roster included 60 fighters competing across six weight classes. The late additions to the season were the welterweights Gleison Tibau, Alexey Kunchenko and Jason Ponet, featherweights Chris Wade and Anthony Dizy, women's lightweights Kaitlin Young and Taylor Guardado and light heavyweight Nick Roehrick.
In December 2021, PFL announced a multi-year partnership for its new PFL Challenger Series with streaming television provider fuboTV on its Fubo Sports Network. Set to debut in February 2022, the new event will see fighters competing for a chance to earn a PFL contract and will incorporate a celebrity judging panel, a fan vote, sports betting and gamification.
