He scored a total of 34 goals in 64 appearances for Rovers before signing for Shelbourne just after the 1994 League success. He stayed with Shels until the end of the 2003 season.
He scored the winning goal in the 1996 FAI Cup Final replay at Dalymount Park against St Patrick's Athletic to deny them the league and cup 'double' and scored the second goal in the following year's final as Shels beat Derry City 2–0 to deny them the 'double'.
In 1999–2000, Geoghegan's goals helped Shels win the League and FAI Cup double for the first time in the club's history. Further league titles would be won in the 2001–02 and 2003 season with Shels. He also had a spell at Dundalk late in his career.
