Celtic have recalled Josh Thompson from his spell at Peterborough and sent the defender back out on loan to Chesterfield.
Thompson spent the first half of this season at London Road but was summoned back from the Championship club after failing to break into the first team.
The 20-year-old will remain with the Spireites until the end of the current campaign.
Thompson has made 21 first-team appearances for Celtic since joining the Glasgow giants from Stockport in a £250,000 deal in 2009.
He spent last season with Rochdale, making 14 appearances.
