Tommy Wright named caretaker-manager following John Sheridan’s departure earlier today.
Wright, who was Sheridan’s assistant, will be assisted by coach Mark Crossley.
Chesterfield chief executive Chris Turner said: "Tommy will take charge of the first-team for the forseeable future.
"We need to take stock of the situation so we are not looking to make an immediate appointment.
"The board would like to thank John for the hard work he has put in over the last three years and wish him well for the future.”
