Aberdeen boss Derek McInnes has ruled himself out contention to become the new Scotland manager.
Tomasz Kuszczak, Greg Stewart and Senegal midfielder Cheikh Ndoye are all released by Championship club Birmingham City.
Aberdeen vice-chairman Dave Cormack says Derek McInnes will be staying as manager even if the Scottish FA makes an approach about being national head coach.
