John Potter joins Dunfermline on one-year deal
Potter, who captained the Buddies, played for the Pars for three years until 2002 when he switched to Clyde.
The centre-half joins Kevin Rutkiewicz, Paul Burns, Paddy Boyle and Paul Gallacher as the Fife outfit's new recruits. McIntyre, who was at the Euro Under-21 Championships in Denmark last week as part of his UEFA Pro Licence course, said: "I am really pleased to bring in someone with great experience and a proven Premier League player.
"He was captain of St Mirren for the last three seasons and he is a real leader on the park. He joins us on a one-year deal."
