Katie Taylor will fight for the WBA lightweight world title on the Joshua v Pulev undercard.
Promoter Eddie Hearn confirmed that the Bray boxer will face two weight world champion Anahi Sanchez for the belt in Cardiff on October 28th.
The 30 year old Irishwoman has won all six of her professional bouts since turning pro after Rio 2016, and has knocked out four of his opponents to date.
Her Argentinian opponent defeated Cecila Sofia Mena to take the the vacant WBA belt, and has a professional record of 17-2-0. However, all of the 26 year old’s victories were won in her native country, with her only two defeats coming on visits to Europe.
“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.”
There are now three world title fights on the card, with Joshua’s defence and Taylor’s challenge complemented by Kal Yafai’s mandatory defence against Japan’s unbeaten super-flyweight Sho Ishida.
Taylor also fought on the undercard of Joshua’s stunning victory over Wladimir Klitschko before a sell-out crowd of 90,000 at Wembley Stadium.
If the former Olympic gold medalist can overcome Sanchez, she’ll be the third Irish female boxer to secure a world professional title, joining Christina McMahon and Deirdre Gogarty on that elite list.
