Chesterfield hope to have Peterborough defender Scott Griffiths back on loan in January.
The full-back played the final game of his three-month spell with the League Two leaders against Harrow in the FA Cup on Saturday.
Football League rules stipulate that a player can spend no longer than 93 days on an emergency loan, so Griffiths is unable to return until the next transfer window.
Spireites boss John Sheridan hopes that will be the case and plans to talk to Peterborough in the near future.
"We are trying to sort something out. Hopefully he will be back with us in January," said Sheridan.
"It`s in the hands of their chairman and (director of football) Barry Fry. We`ve had positive feedback and hopefully we can get it sorted out."
