O'Shea started as Right Wing Back and played most of the game until he was replaced by Daniel Bohane.

He did not start in the 2009 League Final but did come on after 72 minutes for Pádraig Reidy as a Left Full Back.
[10][11][12] O'Shea did not play in Kerry's first two games in the 2009 Championship versus Cork but will start as Right Wing Back in Kerry's first qualifier game versus Longford.
