A member of Sligo Rovers' First Division Championship winning squad of 2005, Stephen is another of Anthony Gorman's closed season signings. A former Finn Harps under-21 players, he made his National League of Ireland debut in the colours of the Bit o' Red from the Showgrounds. A tough tackling midfield player, O'Donnell scores more than his fair share of goals. Scored a goal in each of Harps' opening two games this season and has four so far this campaign.
