A deal has been agreed to sign a keeper on an emergency loan following Cameron Dawson's return to Sheffield Wednesday.
A club spokesman said: "Subject to the necessary paperwork being completed, the keeper in question will train with the squad in preparation for Saturday's game at Stevenage.
"We would like to thank Cameron for providing cover at short notice and wish him all the best for the future. We are also grateful to Sheffield Wednesday for allowing Cameron to join us on a temporary basis."
Dawson, who made two appearances for the Spireites, was recruited after Joe Anyon suffered a broken arm.
