John Pemberton has been appointed as Chesterfield manager until the end of the season, following a spell as caretaker boss.
He took temporary charge on 2 January after John Sheridan was sacked.
Pemberton turned to coaching after a 15-year playing career, and has also worked with Nottingham Forest, Sheffield United and Bristol City.
"It's something that makes a little bit of sense at the moment." Pemberton told the club website.
