Colchester United have appointed Wayne Brown as caretaker manager.
The former U's defender, who has been in charge of the club's youth team, will be assisted by John McGreal while the Sky Bet League One club search for a new permanent boss following the sacking of Tony Humes.
Humes was shown the door last week after a run of one win in nine matches left Colchester hovering just above relegation zone.
They are currently in 20th place following Saturday's 5-1 defeat at Burton Albion when Richard Hall took temporary charge.
Humes had been manager since September 2014 when he stepped up to replace Joe Dunne, winning 22 of his 67 games at the helm.
Chairman Robbie Cowling told his club's official website: "Wayne Brown and John McGreal have been asked to take charge of first team matters at Colchester United on a caretaker basis whilst with the help of my fellow directors, I determine the next full-time management team.
"I am pleased to say that they have both accepted those roles and I would like to express my thanks to them both for helping the club out.
"I hope everyone involved with Colchester United can get behind Wayne and John and give them their full support. Richard (Hall) very much remains a part of the club and the equation going forward."
