Colchester United have rejected a bid from local rivals Ipswich Town for their winger Brennan Dickenson.
The 23-year-old has been a big hit since joining on a free transfer in the summer.
The former Gillingham man has scored seven goals in 23 appearances to help the U's into the League Two play-off positions.
Ipswich are in the market for fresh recruits to help breathe life into their stuttering Championship campaign, and wrapped up a loan deal for Leeds midfielder Toumani Diagouraga yesterday.
League Two Colchester United have signed Cardiff City midfielder Tommy O'Sullivan for an undisclosed fee.
The 22-year-old has signed a contract with the U's until June 2018.
He made three appearances for Cardiff's first team after coming through the club's academy system and has also spent time on loan at Port Vale and Newport County.
O'Sullivan is the second Cardiff player to join John McGreal's side this month, following the arrival of Eli Phipps earlier this week.
Southend United have signed former Ipswich Town striker Frank Nouble on a deal until the end of the season.
The 25-year-old was recently released by League One rivals Gillingham after joining them on a short-term contract in the autumn.
Nouble has also played for the likes of West Ham and Coventry City in a nomadic career, as well as enjoying a spell at Chinese club Tianjin Quanjian.
Meanwhile, Colchester United have signed Cardiff City forward Eli Phipps for an undisclosed fee.
Colchester United's manager John McGreal has been named League Two Manager of the Month for December.
The U's ended the month unbeaten to lift themselves to just outside the play-offs having earlier been fighting relegation.
McGreal saw off competition from Cambridge United's Shaun Derry, Gareth Ainsworth at Wycombe Wanderers and Exeter City's Paul Tisdale.
He says the award is down to a team effort.
It’s very flattering to receive the award...but the credit must go to the players for the way they’ve adapted to what we’ve asked them to do.
We’ve changed the system, had players come back from injury and the whole squad has had the belief and talent to go out there and perform.
Even during the run without winning, they believed in themselves and the results in December were a reward for their hard work and application.
They’ve shown what they are capable of and we all want to continue December’s form into the New Year and the second half of the season.
Colchester manager John McGreal and Cambridge United's Shaun Derry are both up for the League Two Manager of the Month award for December.
They're up against Gareth Ainsworth at Wycombe Wanderers and Exeter City's Paul Tisdale.
Colchester ended the month unbeaten to lift themselves to just outside the play-offs having earlier been fighting relegation.
Meanwhile, Cambridge moved into play-off positions after they're unbeatable run and only dropping two points in their last seven league matches.
The winner will be announced on Friday.
We look at how our clubs are coping without the emergency loan window as they prepare to do business again in January.Read the full story ›
Colchester United have signed former Shrewsbury Town defender Jermaine Grandison on a free transfer.
The 26-year-old has been on trial with the U's recently and has done enough to earn a deal until the end of the season.
Grandison made more than 150 appearances during his time at Shrewsbury, but was released in the summer.
Colchester United captain Luke Prosser has been ruled out for the rest of the season after undergoing surgery on a serious knee injury.
The 28-year-old defender has been a regular in the U's side since joining on a free transfer in the summer but will now have to sit out the remainder of the campaign.
The news following the surgery isn't what we all wanted to hear.
We were hoping that it was just something minor in the knee and the operation could clear it up for Luke to be back in a couple of weeks or so.
Sadly, that isn't the case and it looks likely that Luke will be out of action for the remainder of the season.
We will know more about the exact nature of the injury once I have spoken to the surgeon myself so we can't give exact timescales for his recovery at the moment.
Colchester United have confirmed the signing of defender Lloyd Doyley on a free transfer.
The 33-year-old Lloyd played over 400 times for Watford, at both Championship and Premier League level and helped them to promotion to the Premier League in 2005/6 season.
A Jamaican international, Doyley will bring plenty of football knowledge to the U's dressing room and he is expected to be part of the squad for the weekend game against Newport.
His move will be completed subject to paperwork clearance.
Colchester United midfielder Doug Loft has been ruled out of the next three months with an achilles injury.
The 29-year-old, who joined the club from Gillingham in the summer, hasn't featured since the defeat to Portsmouth last month and is now facing a prolonged spell on the sidelines.
A partial tear was discovered and it has necessitated an injection and a protective boot.
He will be in the boot for the next few weeks, although he will still be able to do plenty of work in that time, including some cross training and bike to keep up his cardio levels.
It is a bit early to predict exactly how long he will be out but two to three months is the estimate at this stage.
