Amanda Nunes will defend her featherweight championship against Megan Anderson at UFC 259, three months after she was originally slated for the title defense.
Brett Okamoto of ESPN reported the news.
Nunes vs. Anderson was originally slated for UFC 256, but the champion pulled out of the bout for an undisclosed medical issue.
"All I was told was she has a 'serious medical issue' and that they're working on rescheduling the bout currently," Anderson said in a statement. "Obviously, it sucks because we've been working so hard for this, but I hope she has a speedy recovery and the goal remains the same. Nothing has ever come easy for me. This is just another part of the journey and we'll be ready for whatever date they set. Our time is coming one way or another."
Nunes is undefeated in her last 11 bouts, currently holding the featherweight and bantamweight championships. She last defeated Felicia Spencer via unanimous decision at UFC 250 in June. Her last loss came at UFC 178 to Cat Zingano all the way back in 2014.
Anderson holds an 11-4 career record, defeating Norma Dumont Viana via knockout at UFC Fight Night in February.
However, she'll likely come in as a huge underdog with losses to Spencer and Holly Holm recently on her resume. Nunes dominated Spencer and knocked out Holm in the last 18 months.
Deiveson Figueiredo and Brandon Moreno fought to a draw at UFC 256 in the replacement main event for Nunes vs. Anderson.
