Donegal hurlers edged past Wicklow in Saturday's Allianz League Division 2B semi-final in Aughrim on a final scoreline of 0-17 to 0-16.
Mickey McCann's side will now face Meath in the league decider.
Wicklow and Donegal had met just two weeks previously in Letterkenny in the regulation league game - with the Garden County running out emphatic winners by 2-24 to 0-11 to earn themselves a home semi-final against the same opposition.
However, Saturday's contest was a much more even affair with Donegal edging to victory by a single point.
