Kayla Harrison says she happily resigned with PFL -- but only after company execs proved they were serious about making a super fight with Cris Cyborg, the undefeated MMA star tells TMZ Sports.
31-year-old Harrison -- a 2x PFL tourney winner -- has made it clear she wants to fight the best (think Cyborg and Amanda Nunes) ... so when Kayla recently hit the free-agent market, she talked to Bellator and UFC.
But, the 12-0 fighter says the PFL bosses convinced her they could put together a Harrison-Cyborg fight in the near future.
