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.
MK Dons manager Robbie Nielson has made his second signing since joining the League One club last month.
He's brought in 19-year-old Harvey Barnes from Premier League champions Leicester on loan until the end of the season.
Barnes made his senior debut for the Foxes this season in their UEFA Champions League tie away at Porto. He's scored five times for the Under-23s this season.
He told MK Dons website: "MK Dons has got a good reputation and everyone has been very welcoming – I’m happy to be here.
It’s a big step from Under-23s football but it’s what I feel I need – I just can’t wait to get out there and start playing."
League Two Cambridge United have signed defender Scott Wharton on loan from Blackburn Rovers until the end of the season.
The 19-year old made his debut in August with the Rovers against Burton and went on to score his first goal for the club in their 4-3 win over Crewe Alexandra in the EFL Cup three days later.
With the loss of Tom Dallison and Josh Coulson injured, U's manager Shaun Derry told the club website his new appointment adds defensive options.
We knew that we needed to add someone in this position because we want to have competition for places across the squad.
Scott certainly adds that competition for the centre back positions, and would allow Harry to go out on loan, whilst also bringing his own qualities to the squad. He is an up and coming defender, who is keen to learn and will provide a strong challenge to both Leon Legge and Mark Roberts.
He’s had experience of senior football this season and has developed well at Blackburn, but this is a great opportunity to pull on the shirt for Cambridge United and show his credentials.
MK Dons boss Robbie Neilson has raided former club Hearts to sign a new forward.
Robbie Muirhead, 20, has signed on a two-and-a-half-year deal for an undisclosed fee.
He told the club's website:
Sorry, this content isn't available on your device.
I like setting up goals and I like scoring – they are things I’d like to bring to the team.
Neilson said the striker was full of potential.
“He’s still a young boy so it will take him some time to settle but he’s got real potential. He’s left-footed and is very good with the ball at his feet."
Stevenage have signed Josh McQuoid on loan from fellow League Two side Luton Town until the end of the season.
The former Bournemouth player joined The Hatters in June 2015 on a three-year deal, where he's scored seven goals in 43 times appearances.
Boro Manager Darren Sarll believes his new signing will make a big impact at the Lamex Stadium between now and the end of the season.
Josh is an attacking player, a very intelligent player and a player I have admired over the last eight or nine years.
It is really important we bring in the right character as our dressing is a real tight knit environment.
As a player he has won leagues, played in the championship and he is a winner. He will definitely give us a different dimension or point to attack compared to what we have had.
Peterborough United's Shaquile Coulthirst has joined League two side Mansfield Town on loan.
The former Tottenham Hotspurs striker joined Posh last January on a three-and-a-half year contract for an undisclosed fee.
He's scored seven goals in 43 appearances in all competitions since making the move to the ABAX Stadium.
The 22-year-old joins Mansfield until the end of the season with the option for a permanent move in the summer.

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.
Ipswich Town were denied a place in the FA Cup fourth round following a shock 1-0 defeat at National League side Lincoln City.
The game looked to be heading for extra time until Lincoln's Nathan Arnold took on the Ipswich goalkeeper and scored within the first minute of injury time.
