After a period without success, Duignan lined out in his fourth Leinster final on 17 July 1994. Playing at left corner-forward he scored a point from play and collected his fourth winners' medal after the 1-18 to 0-14 defeat of Wexford. Duignan, who had been prone to injury, suffered ligament damage during that game and was dropped from the starting fifteen for the All-Ireland final against Limerick on 3 September 1994. He was introduced as a substitute for Daithí Regan, however, Offaly looked like losing the game when they trailed by 2-13 to 1-11 with just five minutes remaining. Two quick goals by Johnny Dooley and Pat O'Connor and five unanswered points secured a remarkable 3-16 to 2-13 victory and a first All-Ireland medal for Duignan.
