Growing up in Clondalkin, sporting achievement was in his genes as his father Michael played for the Ireland national field hockey team. Con had short spells with Shamrock Rovers F.C. and Drumcondra F.C..
Con made his League of Ireland debut as a replacement for Damien Richardson at Sligo Rovers on the 17 October 1971. In his second League game he scored his first goal at Glenmalure Park against Limerick on the 31st October. He made a total of 16 appearances including 2 each in the Texaco Cup and the FAI Cup scoring 3 goals.
In 1980 he replaced former University of Arkansas All American kicker Steve Little for the St. Louis Cardinals.  He is most famous for having missed a game winning kick against the Washington Redskins in the last game of the 1984 season that would have sent his St. Louis Cardinals to the playoffs, and also for missing three field goal attempts in overtime of a Monday Night Football game against the New York Giants during the 1983 season, resulting in a 20-20 tie.
