The PFL is preparing to launch its new Challenger Series and has revealed a few familiar faces will be a part of the experience. This new series of events will seek to find talent to compete in upcoming PFL seasons and will have a judging panel consisting of athletes combined with votes from the fans watching along. A pair of former UFC champions, Vitor Belfort and Tyron Woodley , will be panel experts for the new series, alongside a few familiar faces that have graced the PFL commentary booth in the past. “I can talk about the panel,” PFL CEO Peter Murray explained to MMA Junkie in a recent interview.
