Doran played international rugby for Ireland and in 1899 he was selected for the British Isles team on its tour of Australia.
Doran is most notable within rugby for scoring the winning try in the final game of the 1899 Home Nations Championship, which gave Ireland their second Triple Crown.
[3] His nickname within the club was Blucher, a reference to Field Marshal Gebhard Leberecht von Blücher, as he always arrived late.
On his return to Britain, Doran was reselected for the Ireland national team, playing in the opening game of the 1900 Championship, a loss against England.
Doran missed the 1901 Championship, but played in the final two games of the 1902 tournament, scoring a try in a win over Scotland, but then losing heavily to Wales.
