PFL 4 took place on Thursday at Universal Studios in Orlando, Florida. This event featured the opening rounds of the 2025 Professional Fighters League World Tournament for the heavyweight and light heavyweight divisions.
The light heavyweight main event saw former Bellator champion Phil Davis make his debut under the PFL banner. He squared off against the 2022 PFL champion Rob Wilkinson. This marked Davis`s first appearance in the PFL after notable careers in both Bellator and the UFC.
Wilkinson was looking to reclaim tournament glory, having been removed from the 2023 tournament following a failed drug test and suffering a loss in the 2024 semifinals.
In the co-main event, former Bellator interim heavyweight champion Valentin Moldavsky faced Sergey Bilostenniy. Bilostenniy entered the fight with an impressive 8-1 record since 2018, with his single loss coming via disqualification to Tyrell Fortune. Bilostenniy later avenged this loss by submitting Fortune in their rematch.
A planned light heavyweight bout underwent a late change. Marcelo Nunes withdrew from his scheduled fight against Sullivan Cauley. Tournament alternate Alex Polizzi stepped in as the replacement, having originally been set to fight Rafael Xavier on the preliminary card.
