Defender Graeme Lee is one of eight Notts County players to be told they can leave Meadow Lane.
Lee, Febian Brandy, Alan Gow, David Grof, Njogu Dembra-Nyren and Kevin Smith are not having their contracts renewed by manager Martin Allen.
Liam Chilvers and Jon Harley can leave, even though they are under contract.
"It is never easy to do this part of the job, especially as they have performed so admirably since I have been here," said Allen.
"What makes it tougher is that they are good people and have been good to work with.
"They are all very good, professional, honest people."
