They secured a five-point victory at Kingspan Breffni Park, with a final score of 0-13 to 0-08.
The pair played out a stunning 2-12 to 2-12 draw last week but today's replay was a much tighter affair.
Patrick Lynch was the leading scorer for the Kilnaleck-based side with five points, two coming from frees. James Smith, who scored three points, put in a man of the match display.
There were chances for both sides and Crosserlough defended very well, holding out for the victory, sparking joyous celebrations from the panel.
