Donegal 0-10 Derry 0-15
In a dress rehearsal for their championship meeting, Derry beat Donegal at Letterkenny to win through to their first NFL Division 1 final since 2000.
Derry will meet Kerry in the league decider and owe this win to a strong first half display which had them leading by 0-10 to 0-3 at half-time.
Michael Hegarty and Colm McFadden (0-2) were the hosts' only scorers during the opening 35 minutes.
And despite an improvement from Donegal, Derry kept ahead with Paddy Bradley claiming six points.
