"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."

Colchester United manager Tony Humes has left the club by mutual consent.
The news was confirmed at a press conference this afternoon.
The U's have decided to act following Tuesday's 3-2 defeat to bottom club Crewe Alexandra, where they threw away a two-goal lead.
Colchester have only won one of their last nine league games, and have conceded more goals than any other team in the Football League.
Humes leaves Colchester in 19th place in League One and just a point outside the relegation zone.
Chairman Robbie Cowling had previously told fans asking for Humes to be sacked to "save their stamps" after several supporters wrote to him asking for a change in management.
Assistant boss Richard Hall and under 21s manager John McGreal will take charge of Saturday's trip to Burton.
"Humes felt that his presence was becoming detrimental to the club and the young players that he had nurtured in his time at the U's and it would be best to remove himself from the equation.
Robbie (Cowling) would like to place on record his thanks to Tony for his hard work, not only over the past fourteen months but throughout the years he has been at Colchester United."
Colchester United have signed striker Marvin Sordell.
Sordell, 24, was once a £3m signing for Bolton but joins the U's on a permanent deal having been released y Championship side Burnley.
It comes a day after chairman Robbie Cowling issued a "save your stamps'' warning to fans who've been writing demanding the sacking of current boss Tony Humes.

Colchester United chairman Robbie Cowling today spoke of his sadness at receiving a letter from fans asking him to sack manager Tony Humes.
The U's are yet to find a win this season, sitting second bottom of League 1 with three points after their first five games.
Manager Tony Humes has been with the club since 2009 when he joined the U's as the Head of Youth. Humes was in charge of the under-18 squad when they won the national Youth Alliance Cup in the 2013-2014 season. Since becoming Manager of the first team at the start of last season, he led the club to safety on the final day of the 2014-2015 season.
Cowling said he understood the fans' frustration, but said sacking Humes would be a "quick fix".
"I know how painful defeat is and how much more painful it becomes when the banter starts once you return to work on a Monday following yet another defeat. Like most pains, you just want a pill to make it go away and in football, the over the counter pill of choice is to sack the manager. If that doesn’t work, then a serious operation is required to have the board removed.
After nine years of owning a football club, I just don’t buy into either of those treatments as a quick fix."
"I find it somewhat offensive when I receive a letter from a supporter of our club asking me to sack the manager. I have received such letters for every one of my managers to date
"Yes, the last three years have been difficult and the next few years won’t be easy either. But I am happy with the way I invest my time, effort and money in the managerial staff we have at Colchester United so if you are thinking of writing to me about my manager’s future, please save your stamps."

Briggs was once the Premier League's youngest player when he made his debut for Fulham at the age of just 16 years and 65 days in 2007.
"He has got a lot of the attributes we’re looking for and he showed at the end of the season that he’s improving with games.
You're looking at him fitting into the back four as an attacking left back and he has a real physicality and technical ability. He has got those attributes in abundance."
