Northampton Town can confirm they have parted company with manager Jimmy Floyd Hasselbaink.
"We are sorry to see Jimmy depart as he has worked very hard for us but felt a change at this point was in the best interests of the club," said Chairman Kelvin Thomas.
"We thank Jimmy for his work as manager of Northampton Town and we wish him the very best for the future."
Kelvin Thomas continued: "We understand we are in a very tough spot and what the task in hand is, but I’m confident that the players, supporters and staff will all unite behind Dean and Jon for the remaining five games of the season. It has certainly been a challenging time for the club, but we need to look forward and put our full focus on these remaining five fixtures."
