Preston North End currently sit in 18th place – nine points above Peterborough – and had recently been struggling with poor form.
The Lilywhites have now sacked Frankie McAvoy and are looking to bring in a new man to lead them to safety, with Plymouth Argyle boss Ryan Lowe a name that has been heavily linked.
Posh remain in the bottom three and are without a win in their previous seven fixtures.
Three points against Millwall at the weekend would take them within touching distance of Cardiff City, who sit just outside of the relegation zone.
