Late goals from John-Paul McGarry and Conor McShea ensured Fermanagh got the better of Sligo in a game switched from Markievicz Park to Bawnacre Centre, Irvinestown because of bad weather.
Sligo led at the break by 1-10 to 0-9 thanks in part to a goal from wing-forward Liam Reidy on 11 minutes.
Points from Keith Raymond kept Sligo ahead but Sean Corrigan ensured Fermanagh only trailed by four points at the break as he landed three first-half frees.
And Fermanagh dominated the last ten minutes of the match, with late goals from corner-forward McShea and centre-forward McGarry securing victory.
