Katie Taylor will fight for her first professional world title on the undercard of Anthony Joshua vs Carlos Takam in Cardiff on 28 October, live on Sky Sports Box Office.
The unbeaten Irish sensation will take on Argentina's Anahi Esther Sanchez, a two-weight world champion, for her WBA world lightweight belt at the Principality Stadium.
The announcement at Monday's press conference means there are now three world title fights on the blockbuster bill, with Kal Yafai's mandatory defence against Japan's unbeaten super-flyweight Sho Ishida completing the trio.
"This is something I've been waiting for since turning pro, I've always wanted to be involved in big fights on big shows, and I hope this is the first of many world title fights," Taylor said.
"Sanchez is a tough opponent, a two-weight world champ but I feel like I am ready. She is very experienced and has a great record as well.
"I want to make history in the sport. I feel like this is what I was born to do, to get this opportunity is a dream for me."
Promoter Eddie Hearn also confirmed that Cardiff's own Joe Cordina, a 2016 Rio Olympian, will box for a title in just his fifth pro fight on the bill as he realises his dream of fighting in the Welsh capital.
'The Welsh Wizard' will be joined on the bill by fellow Olympians Lawrence Okolie and Joshua Buatsi, a bronze medallist from those Games.
It has already been confirmed that Frank Buglioni and Callum Johnson will clash for the British and Commonwealth light-heavyweight titles, while David Allen has a chance to seek revenge on Jamaican Lenroy Thomas.
The Doncaster heavyweight suffered an agonising split-decision defeat to Thomas in their Commonwealth title clash back in May.
