Northampton Town have parted company with manager Keith Curle and assistant manager Colin West.
Chairman Kelvin Thomas said the decision was taken with a heavy heart but was in the best interests of the club.
"We have a huge amount of respect for Keith and Colin and we will always owe them a debt of gratitude for the promotion they achieved but we feel a change is now required," he said.
"Our results, and in particular our lack of goals, have left us in a very difficult position in the league and we believe that this decision is in the best interests of the club as we battle to retain our League 1 status.
"Keith and Colin leave with our thanks and our best wishes and their time at the club will go down as a success, especially managing us through the difficult period of Covid 19."
Under 18s coach Jon Brady has been placed in caretaker charge, to be assisted by Ian Sampson and Marc Richards.
"Jon has a wealth of experience both as a player and a manager, he also has a good knowledge of the club and our younger players and we are fortunate to be able to call on him," said the Cobblers Chairman.
"He will be assisted by Ian Sampson and Marc Richards. Both are rightly Northampton Town legends, they have a huge amount of experience in the game and a deep knowledge of and affection for the club and I am sure all supporters will join me in wishing Jon, Ian and Marc well.
"Although supporters might not be able to attend games at the moment, the support they offer is as vital as ever. It has been a challenging season off the field and we can't thank the fans enough for that continued support. We now have a very important 20 games left in the season and we know they'll be right behind us."
