On 18 July 1993 Corcoran made his senior football championship debut in a 1-16 to 1-8 provincial final defeat of Tipperary. It was his first Munster medal. On 19 September 1993 Cork faced Derry in the All-Ireland decider. Cork got off to a good start, however, Derry capitalised on some careless play to take the lead. Tony Davis was wrongly sent off for what was later seen as a legal challenge. Enda Gormley scored six points for Derry, however, it was Séamus Downey who scored the decisive goal as Derry secured their first All-Ireland following a 1-14 to 2-8 victory.
