St Mirren have told 10 out-of-contract players that they will have to find new teams for next season.
They include defender John Potter, who captained the club, and forwards Craig Dargo and Gareth Wardlaw.
St Mirren boss Danny Lennon said: "John has been with us through the last promotion and was also captain. He has done a terrific job for us.
"We would like to wish all of the players released the best of luck for the future."
The other players who are not being offered new contracts are Garry Brady, Patrick Cregg, Sean Lynch, Nick Hegarty, Jamie McCluskey, Kyle Faulds, Mark McLennan and Ally Love.
St Mirren secured their Scottish Premier League survival on Tuesday night, when they beat Aberdeen and Hamilton were relegated after defeat by St Johnstone.
Wardlaw, who Lennon brought with him from Cowdenbeath in the summer, was the Buddies' scorer at Pittodrie, taking his tally to three goals from 24 appearances.
Dargo joined St Mirren in 2007, although his time in Paisley has been dogged by injury and he scored almost half of his 12 goals this term.
"We are grateful for the job that each of these players has done for the club," added Lennon.
Potter, who signed in 2005, and Brady, who arrived a year later, were the longest-serving of the 10 players.
Cregg, Lynch and Hegarty only joined the club this season.
