Professional Fighters League

Professional Fighters League (formally World Series of Fighting) is a U.S.-based mixed martial arts league founded by Donn Davis in 2017 and launched in 2018. PFL is the first major MMA organization in which individual athletes compete in a regular season, post-season and championship, rather than on a year-round basis.
