Colchester has parted ways with head coach Steve Ball after a 13-game winless streak in League Two.
A 2-1 loss by promotion hopefuls Exeter City on Tuesday left 21st U in the standings, nine points out of the relegation zone.
Colchester appointed former player and assistant manager Ball, 51, last July as the successor to John McGreal, who left the club following his loss to Exeter in last season’s play-off semi-finals.
In a statement from the club, owner and chairman Robbie Cowling said: “After tonight’s game and a discussion I had with Steve, it was decided the best way forward was for him to leave his home. head coach position.
“Steve has been with the club in different capacities for a long time and I would like it to be recorded our thanks to him for his hard work and dedication.”
Ball’s last victory in charge was a 1-0 victory at Scunthorpe on December 8.
Colchester has not disclosed who will take the interim charge, or whether Ball’s assistant Hayden Mullins will remain at the club.
