Claressa Shields vs Savannah Marshall undercard announced

On an historic night for women's boxing, the undercard for Claressa Shields (12-0 2 KOs) vs Savannah Marshall (12-0 10 KOs) at the O2 Arena, has been announced and it features a world title unification and three Tokyo 2020 Olympians.

In the co-main, a fight worthy of a headline slot, Mikaela Mayer (17-0 5 KOs) faces bitter rival Alycia Baumgardner (12-1 7 KOs) with the IBF, WBC and WBA world titles on the line.

Mayer comes into this fight unbeaten in her 17 outings so far, making her fifth appearance in a world title fight. She most recently beat Jennifer Han in April over 12 rounds.

Baumgardner holds just one career loss to date, since then she has built up momentum and won six consecutive fights picking up WBC and IBO world titles. The American stunned Terri Harper late last year to snatch the world title in just 4 rounds and ever since that victory, she was very vocal about wanting to fight Mayer.

Olympic gold medalist, Lauren Price (1-0), looks to carry on her progress in the professional ranks after her succesful debut in June as she takes on Timea Belik (6-6).

One of the most promising female fighters from the UK shores and fellow Olympian, Caroline Dubois (3-0 2 KOs), takes to the ring for the fourth time this year when she fights Milena Koleva (10-14-1).

Kariss Artingstall, Ebonie Jones and April Hunter also join the all female card at the O2 Arena.
