Blackpool boss Simon Grayson has begun planning for life in the Championship by releasing Ciaran Donnelly, Sean Paterson and Marc Joseph.
But new contracts at Bloomfield Road have been offered to Phil Doughty, Danny Coid and Matt Blinkhorn.

And young right-back Scott Metcalfe has also been offered a contract.
