Ten players are leaving St Mirren following their relegation from the Scottish Premiership.
Gregg Wylde, Marian Kello, Victor Genev, Jeroen Tesselaar and Yoann Arquin have been released.
Youth team players Mark Williams, Mo Yaqub and Adam Brown are also exiting, along with on-loan duo James Dayton and Emmanuel Sonupe.
New manager Ian Murray will hold talks with Steven Thompson, Alan Gow and John McGinn, who are all out of contract.
If McGinn, 20, moves on the Paisley club will be due around £270,000 in compensation.
Winger Kieran Sadlier, who spent the second half of last season on loan from West Ham, has been invited back for pre-season training, as has Thomas Reilly.
The 20-year-old Reilly made his Buddies debut in January 2012 and made 23 appearances last season.
