Antrim fought back from six points down to beat Fermanagh 2-11 to 2-9 in the Ulster MFC in a game refereed by Cavan woman Maggie Farrelly.
The Cavan referee became the first woman to referee at this level as Antrim won despite Paul O'Reilly's two early Fermanagh goals.
O'Reilly's strikes helped the Erne boys lead 2-3 to 0-3 but a Brendan Corr goal cut the margin to three by half-time.
Conor Small hit eight Antrim points as Kevin Small netted their second goal.
Antrim's win at Brewster Park sets up a semi-final against Cavan.
