League Two strugglers Grimsby Town have transfer-listed four of their squad.
The Mariners, who are second from bottom, have circulated the names of Barry Conlon, Danny Boshell, Jamie Clarke and Matt Heywood.
All four players have been told they can leave the club on free transfers if they find themselves new employers.
Boshell, Clarke and Heywood have not appeared much under new boss Neil Woods.
But Conlon is the club's current top-scorer with five goals.
Grimsby have also made Danny North available for loan.
