Ariel Helwani of ESPN first reported the news, as the fight was originally set to take place at both UFC 249 and UFC 250 being the coronavirus pandemic and injuries caused the bout to be pulled from those cards.
Nunes (19-4-0) will enter the title bout riding a ten fight winning streak and seven of those contests were title bouts. Nunes hasn’t suffered a defeat in over five years, with that last loss coming to Cat Zingano at UFC 178 in September of 2014. Nunes would be competing in her eighth straight title fight, but is making the first defense of her women's featherweight title.
