The lawsuit, filed in New Jersey, also names several top PFL executives such as co-founder Donn Davis, CEO Peter Murray, and matchmaker Mike Kogan.

The veteran middleweight's legal team has presented an 81-page document outlining Mousasi's complaints. According to the contract signed with Bellator in 2017 and extended in 2020, Mousasi was promised a guaranteed payment structure beginning at $150,000 for his first four bouts and escalating to $200,000 per bout thereafter. Additionally, he was to receive a $50,000 finish bonus for victories via knockout or submission, along with a promotional fee of $600,000 per bout after the first four, summing up to $800,000-$850,000 per fight.

The crux of Mousasi's complaint centers on his lack of scheduled fights after fulfilling the initial four-fight agreement. He alleges that despite being injured, he accepted a fight against Fabian Edwards out of concern that he would otherwise be sidelined indefinitely. His situation reportedly deteriorated further following Bellator's acquisition by PFL in November 2023, with continued silence and inactivity enforced by the promotion.

Mousasi voiced his frustrations earlier in the year, stating he struggled to communicate with PFL officials about his career status. "They refuse to answer us back," Mousasi told MMA Fighting in April. "I've been training, I've been ready. But they don’t promote me, or people think I'm retired actually."

The lawsuit chronicles numerous attempts over several months by Mousasi's manager to engage with PFL executives, efforts that ultimately led nowhere. Following a threat of legal action, PFL and Bellator announced his release from the contract in May. Now, Mousasi is pursuing legal redress, accusing Bellator and PFL of breaching the implied covenant of good faith and fair dealing, unjust enrichment, and engaging in anti-competitive monopsony conduct.

In his legal filing, Mousasi is seeking compensatory, consequential, and/or equitable monetary damages amounting to no less than $15 million, along with punitive damages and coverage for attorney fees.
