Carlisle United's League Two rivals Colchester United are the latest to confirm the appointment of a new boss.
The Essex club have handed Hayden Mullins the permanent head coach role.
Mullins had been in interim charge for the last eight games of the 2020/21 season.
After keeping the Us in League Two, the former Crystal Palace, West Ham and Portsmouth player has now been asked to remain at the helm for next term.
Mullins had joined Colchester last summer as assistant to Steve Ball, and remained in that role during Wayne Brown's brief interim period in charge later in the campaign.
Colchester said Mullins' appointment followed a spell when he gained 12 points from eight games to see off the risk of dropping into non-league.
They finished 20th, six points clear of the relegation places.
Mullins' appointment is the latest piece of managerial news in United's division, with Salford having earlier confirmed Gary Bowyer's return as their boss for next season.
Other clubs including Bradford, Walsall and Leyton Orient are seeking new managers.
