Two-weight world champion Natasha Jonas will defend her IBF welterweight belt against former Ring junior lightweight world champion Mikaela Mayer in a landmark night for women’s boxing as two of the sport’s biggest stars meet in the centre of the ring on Saturday, January 20th at the M&S Bank Arena in Liverpool, live on Sky Sports in the UK and Ireland.

Jonas (14-2-1, 9 KOs) will be making a first defense of the IBF crown she claimed with a stoppage win over Canadian Kandi Wyatt earlier this year, having previously unified the IBF, WBC, and IBF junior middleweight belts and earning the inaugural Ring championship in that division.

Standing in the opposite corner will be U.S. star Mayer (19-1, 5 KOs), a fellow Olympian and former IBF and WBO titlist at 130 pounds. The Los Angeles native is moving up in weight once again after a short stint at 140 pounds.

Natasha Jonas said: “I’m so excited to be fighting back in Liverpool in my first headline show and in the biggest fight of my career so far. It’s my fifth world title fight with Boxxer, in my backyard and I’m ready for it. It’s Mikaela Mayer, she stretches above and beyond the UK shores. ‘Miss GB’ versus ‘Miss USA’ and may the best woman win!”

Mikaela Mayer said, “These are the types of matchups boxing needs. I am feeling better than ever at my new weight and confident that 2024 is when I take it all back.”

Boxxer Founder and CEO, Ben Shalom, said: “2024 promises to be a monumental year for Boxxer and Sky Sports, and we’re thrilled to kick things off with another massive night for women’s boxing as Natasha Jonas defends her World Title against Mikaela Mayer in a matchup set to showcase the pinnacle of the sport. Natasha and Mikaela are two fantastic athletes – both former Olympians and world champions – from either side of the Atlantic, ready to put it all on the line to secure their legacy.”

“Mikaela Mayer is beloved in the UK, and we are thrilled that she will get an opportunity to become a two-weight champion against a sensational fighter in Natasha Jonas,” said Top Rank Chairman Bob Arum. “These are two of the best pound-for-pound females in boxing and a great fight to kick off the 2024 schedule.”

In the undercard, newly crowned British and Commonwealth Champion Jack Cullen also returns to action in Liverpool defending his belts against former foe Zak Chelli. Cullen (22-4-1, 10 KOs) scored a memorable third-round TKO win over Mark Heffron in September to claim the British and Commonwealth titles. ‘Little Leaver’s Meat Cleaver’ will now square off against former English Champion Chelli (14-2-1, 7 KOs) in a repeat of their all-action 2020 contest that ended in a draw.
