The two sides' two previous meetings that season had been in the
League, with Dundalk winning both matches – including a 3–0 victory in
The Showgrounds in
Sligo two weeks earlier. Dundalk had finished as runners-up in the
1980–81 League of Ireland, and had already won that season's
League Cup. To reach the final they had defeated non-League Hammond Lane (1–0),
St Patrick's Athletic (2–0 in a replay following a 1–1 draw),
Drogheda United (1–0 in a replay following a 0–0 draw), and
Finn Harps (1–0). Sligo Rovers were the underdogs, having finished 11th in the League, and were playing in their fifth
FAI Cup final. They had lost in all four of their previous appearances, most recently in 1978. They had overcome UCD (2–1 in a replay following a 1–1 draw),
Home Farm (3–0), and
Waterford (1–0 in a replay following a 2–2 draw) to reach the final. The match was not broadcast live. Highlights were shown that evening on the
RTÉ show
Sports Scene, with commentary from
