Young striker Ricky German has joined Sheffield FC on loan for a month.
German has joined the Evo-Stik League First Division South club after completing a spell on loan at Alfreton Town.
The 18-year-old made four starts during his time with Alfreton and scored two goals.
German, who is a product of Chesterfield's academy, has made ten first-team appearances for the Spireites, including one start.
His solitary appearance for Chesterfield this season came as a substitute in the Carabao Cup tie at Sheffield Wednesday in August.
