The undercard for Caroline Dubois vs Terri Harper has been significantly strengthened with the addition of Tysie Gallagher, Britain's first female super-bantamweight champion, and IBF No 1 contender Elizabeth Oshoba. The April 5 event at London's Olympia will feature four world title fights and eight belts at stake, marking a historic night for women's boxing in Britain.

Gallagher, who made history as the first-ever female British super-bantamweight champion, will face Finland's unbeaten Teresa Makinen in her MVP debut. The 35-bout amateur standout, who also contested for the WBO world title in 2023, brings extensive experience to the card. Oshoba, a decorated Nigerian amateur who relocated to the UK, will make her promotional debut against Chelsey Arnell in a six-round bout using the same three-minute rounds as men's boxing.

Former WBA titlist Shannon Courtenay returns to fight in front of her home fans against Nottingham's Sasha Booker, while rising star Gemma Richardson faces Czech boxer Johana Rochl in a six-round lightweight bout. The stacked undercard builds toward the double main event featuring Dubois-Harper's world lightweight unification and Ellie Scotney's undisputed world championship shot against Mayelli Flores, live on Sky Sports.
