Southend United centre-back Luke Prosser has joined Northampton Town on loan until the end of the season.
The 27-year-old has been with the Shrimpers since 2010, but has found first team opportunities harded to come by this season in League One.
Prosser's contract at Roots Hall expires in the summer.
"I'm really pleased to bring Luke in.
I have been an admirer of his for a while and this is another signing that will strengthen us at a key time in the season.
As James Collins did, Luke also won promotion from this level last season, and that knowledge and experience can only help us.
We have a really hectic schedule coming up, and to be able to add Luke's ability, knowhow and experience to the squad is a big boost and a huge help to the players who are already here and have done so well to get us to the position we are in."
Meanwhile, former Southend loan star Joe Pigott will spend the rest of the campaign at Luton Town.
Pigott has signed on loan from Charlton Athletic and helped Southend gain promotion from League Two last season.
“I’ve worked before Joe before. He’s an excellent young striker who has scored goals wherever he has been.
He’s been brought into the Club because he is the type of player we want here. He fits all of our criteria and adds competition to an area we are already very strong in."
Elsewhere, Stevenage defender Jamie McCombe has left the club by mutual consent.
Northamptonshire Police have confirmed a 45-year-old man is helping with inquiries in relation to the investigation into the use of funds loaned to Northampton Town FC by Northampton Borough Council.
The man was arrested by detectives at an address in Northamptonshire on Monday morning. He has been released on conditional bail.
“This remains a very complex investigation and, as such, it would be inappropriate for us to make any further comment at this time.”
Northampton Borough Council loaned the League Two club £10.25million to complete a stadium development in 2013.
The proposed work was never completed and, in November 2015, police launched an investigation into "alleged financial irregularities".
Despite numerous off-field problems this season, the Cobblers are top of the table after 27 games.
MK Dons have signed Crystal Palace midfielder Jonny Williams on a 93-day emergency loan.
Welsh international Williams has been on loan at Nottingham Forest this season, and has also played for Ipswich Town.
“Jonny is someone who I’ve always liked from a young age. He really suits our style – he’s a very offensive player and can play in a variety of positions.
He’s also got an unpredictability about him and a low centre of gravity which gives him that ability to drive past people. He had a massive impact on helping Palace get promoted from this division – I’m really excited about what he can bring.
We'd have loved to have done this deal until the end of the season but as he's played for Crystal Palace and already been out on a standard loan this season, a 93-day loan is the longest we can acquire his services for."
In other transfer news, Luton Town defender Luke Wilkinson has joined Stevenage on a permanent deal while Alan Sheehan has joined the Hatters on loan until the end of the season.
Southend United have signed Southampton's Sam McQueen and Arsenal youngster Glen Kamara on loan deals until May.
Ipswich Town have terminated the contract of Australian winger Tommy Oar.
Oar only joined in the summer, but has failed to settle in England.
The 24-year-old wants to move closer to his family in Australia, and although Town were keen to keep him, manager Mick McCarthy has reluctantly allowed him to leave.
"I’d like to thank Ipswich Town for their co-operation over ending my contract.
It’s a great club and the manager, staff and players made me feel very welcome but while I have enjoyed playing for Ipswich, I have found it difficult to settle into life in England.
I have been away from home for five or six years now. My family came over at Christmas and maybe I’ve got to a point where I want to be closer to home again.
It’s just one of those things where moving over here as not worked out as I had hoped but I’d like to wish the club, the manager, the staff and the players the best of luck over the rest of the season and I hope to be watching Ipswich in the Premier League next year.”

Ipswich Town manager Mick McCarthy has extended his contract with the club until 2018.
McCarthy has had a big impact at Portman Road since joining in 2012 and led Town to the play-offs last season despite working on a limited budget.
Ipswich are competing again at the right end of The Championship and currently sit just outside the top six.
Assistant boss Terry Connor has also been given a new deal.
“TC (Terry Connor) and I are obviously delighted to have extended our contracts. We are really enjoying the job here and the results on the pitch have improved year on year.
In a relentless and tough league that the Championship is, that is testament to the hard work the players have put in. I think we have a team we can all be proud of and it’s mine and TC’s job to make sure that continues.”
Norwich City striker Gary Hooper has joined Sheffield Wednesday on a permanent deal.
Hooper has impressed while on loan at the Championship club and has now completed a move to Hillsborough for an undisclosed fee.
The 27-year-old joined Norwich for a fee of £5 million from Celtic in 2013 and went on to score 20 goals in 70 appearances.
Hooper has signed a three-and-a-half year deal in Yorkshire.
Ipswich Town have completed the signing of former Wolves defender Kevin Foley.
Town have been on the lookout for a full-back since they sold Jonny Parr to Norwegian side Strømsgodset earlier this month.
31-year-old Foley was recently released by FC Copenhagen and played under manager Mick McCarthy at Wolves.
He's signed a contract until the end of the season.
“This is a great club and I’m delighted to be here.
It’s taken a bit of time due to the international clearance and stuff but I’m just happy it’s done now. I really enjoyed my time here anyway and a door sort of opened up for me once Jonny Parr departed.
I know the gaffer and TC (Terry Connor) from our days at Wolves and it’s great to work with them again. They know what I’m all about and likewise I know how they work."
Peterborough United have signed highly-rated Tottenham Hotspur striker Shaquile Coulthirst for an undisclosed fee.
The 21-year-old has spent time out on loan at several clubs, but has now agreed a permanent three-and-a-half year contract at the ABAX Stadium.
Posh beat a number of other clubs to sign Coulthirst.
"He is a sought after player, we are not the only club at the top of our league that have been after him so I am delighted that he has decided that we are the place he wants to join.
I think he wants to try and become the next Conor Washington, the next Craig Mackail-Smith, the next Britt Assombalonga and he has all the talent and attributes to fulfil that."
Peterborough United have strengthened their squad with the signing of two Premier League players.
Left-back Harry Toffolo has agreed a loan move until the end of the season, while Posh have also captured West Brom midfielder Adil Nabi for an undisclosed fee.
"Harry is a terrific young player, he showed at Swindon in League One last year what he can do. He has gone to the Championship this year and it hasn't been the most successful loan for him and I think he is delighted to be here, and closer to where his parents live in Stevenage.
Nabi is a long story because it goes back to me wandering up one night to watch Kemar Roofe play for West Brom under 21s. Kemar did well to be fair, but I came away with the name Nabi on my lips. He was outstanding, he scored a brilliant hat-trick, but it wasn't just the hat-trick, it was his all round display.
I have had my eye on him ever since. He went out to India and played some football, he is back, he is available and I am pleased to have him here at the football club. I think the fans are going to love him."
Both players will help fill the void left by striker Conor Washington who joined QPR earlier this week.
Defender Miles Addison has been released.
