Doran won his first Leinster medal in the senior grade in 1968 following a 3–13 to 4–9 defeat of reigning provincial and All-Ireland champions Kilkenny. This victory allowed Wexford to advance to an All-Ireland final against Tipperary, the outstanding team of the decade, on 1 September 1968. All was going to plan for Tipperary as they took a 1–11 to 1–3 lead at half-time. In one of the great All-Ireland comebacks, Doran got Wexford back on track with a goal six minutes after the interval. Three more goals followed from Paul Lynch, Jack Berry and Doran again. Late goals from Michael "Babs" Keating and Seán McLoughlin for Tipp failed to stem the tide as Wexford secured a remarkable 5–8 to 3–12 victory. It was Doran's first All-Ireland medal.
