Young midfielder Ellis Chapman has joined Chesterfield on loan from Lincoln City until the end of the season.
John Sheridan describes Chapman as "a very good young player".
The Spireites boss adds: "He'll add good balance to the squad. He's capable of playing at left-back as well as on the left-hand side of midfield."
The 18-year-old returned to Lincoln in 2017 after being signed by Leicester City the previous year.
He has made a total of eight first-team appearances, including six this season.
