Young goalkeeper Artur Krysiak, defenders Franck Queudrue, Gregory Vignal and Jared Wilson and striker Gary McSheffrey will leave St Andrews when their contracts expire at the beginning of June.
Also leaving the club is Finland internatrional Teemu Tainio who has now returned to parent club Sunderland following an injury-blighted season long loan deal at St Andrews during which time he made just six appearances.
