Hughes will undergo surgery at some point next week.
“I’m out of PFL Belfast,” Hughes said on Instagram. “I’m sorry to all of my supporters. I am absolutely crushed. The card will go ahead featuring the best talent the island has to offer, including my teammates Caolan Loughran, Rhys McKenna, and the future of Irish MMA, Eoghan Masoliver. I will be back as soon as humanly possible. The obstacle is the way.”
The new main event will feature Wilson against rising Irish star Darragh Kelly.
PFL Belfast will stream live in the United States on ESPN2, ESPN App and ESPN Deportes.
