Former UFC star Molly McCann will make her boxing debut on the undercard of Paddy Donovan and Lewis Crocker's world title contest at Windsor Park.
Liverpool's McCann, who retired from MMA in March following defeat by Alexia Thainara at UFC London, said she wants to "win a world title within eight fights" after signing with Eddie Hearn's Matchroom Boxing earlier this month.
The 35-year-old's opponent for the 13 September fight in Belfast has not yet been announced.
McCann won 14 of her 22 fights across a 10-year MMA career.
Irish boxers Caoimhin Agyarko and Tyrone McKenna have also been added to the Windsor Park card.
Unbeaten middleweight Agyarko, 28, will face 30-year-old Englishman Ishmael Davis, while 35-year-old McKenna will take on fellow Irishman Dylan Moran.
McKenna stopped Moran in the second round of their welterweight contest in Waterford last December.
Matchroom have also confirmed Patrick Brown, who represented Great Britain at the 2024 Olympics, and Commonwealth Games bronze medallist Aaron Bowen will appear on the bill, with more fights still to be added.
