Struggling Donegal Celtic beat visitors Ballinamallard United at Suffolk Road thanks to Ciaran Burns' goal.
Burns turned the ball home after a corner in the 73rd minute.
In the first half, Jason McCartney shot wide of the post and John Connolly easily gathered an attempted overhead kick by Leon Carters.
David Kee twice went close in the second half while DC had Paul Bradley sent-off for a second bookable offence three minutes into added time.
Celtic travel to Coleraine next week while Ballinamallard are at home to leaders Cliftonville.
