Peterborough United striker Lee Angol has joined Conference leaders Lincoln City on loan until the end of the season.
The transfer window is shut for Football League clubs, but teams outside the top four divisions can still bring people in.
22-year-old Angol has made 17 appearances for Posh this season, but has only scored once.
The former Luton Town forward won't be able to feature in the Imps' FA Cup quarter-final at Arsenal later this month though having already appeared in the competition for Peterborough.
Port Vale midfielder Anthony Grant has joined Peterborough United for an undisclosed fee.
The 29-year-old, who has also played for Southend United and Stevenage earlier in his career, has signed a two-and-a-half year deal.
Despite chairman Darragh MacAnthony promising a "quiet day", Grant is the second new arrival following Craig Mackail-Smith's loan move.
He is a really difficult opponent. He has been captain at Port Vale, he is a leader on and off the pitch and I think he will bring a lot to the dressing room.
He has an excellent passing range, he dictates games and he will help us moving forward.
Peterborough United signed striker Craig Mackail-Smith for a third time.
The 32-year-old has re-joined Posh on loan from League Two side Luton Town for the rest of the season.
He is stuck on 99 goals for Peterborough and will be hoping to bring up his century in his latest spell at the ABAX Stadium.
Mackail-Smith has struggled to break into the Luton team this season, with manager Nathan Jones going for other options up front instead.
I am delighted to have him. I feel as if the squad need one or two older heads and he brings that.
He also has a real passion for this football club, you can't buy that. I feel like Craig has a point to prove.
Meanwhile, 19-year-old striker Freddie Hinds has joined Championship side Bristol City for an undisclosed fee.
Peterborough United chairman Darragh MacAnthony has told fans on social media that the club are expecting a quiet deadline day tomorrow.
Posh have seen their form dip dramatically in recent weeks, conceding 11 goals in their last four games, but MacAnthony is refusing to panic.
When asked by one supporter on Twitter whether a busy 24 hours was in store, MacAnthony replied that it will be "very quiet".
Watch Donovan Blake's interviews with MK Dons boss Robbie Neilson and Peterborough manager Grant McCann.
Robbie Neilson hailed the victory over regional rivals Peterborough as a "strong performance".
The MK Dons boss said he was delighted by way his team played and singled out Chuks Aneke for praise.
"He's been fantastic in the time I've been here, he's had a really tough year, he's been building his fitness back up. I think you could see the spirit in the team and the regard they hold him in, and the way they went to celebrate with him after his goals. It was great for him, he's a great kid."
Peterborough manager Grant McCann was left frustrated. Saying his team 'just folded' after going behind.
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.
League One Peterborough United couldn't produce an FA Cup shock at Premier League leaders Chelsea.
First half goals from Pedro and Michy Batshuayi gave Posh the proverbial mountain to climb at Stamford Bridge, a task which got tougher when Willian made it 3-0 after the break.
Chelsea had John Terry sent off before Tom Nichols gave Posh fans something to cheer by scoring with 20 minutes left.
But Pedro ended any hopes of a dramatic comeback by scoring his second and Chelsea's 4th.
Around 6,000 Peterborough supporters watched the game in West London, while many more followed the action on a big screen at their home ground the ABAX Stadium.
Peterborough United supporters were in optimistic mood as they dreamed of an Emirates FA Cup upset at Premier League leaders Chelsea.
Posh will have around six thousand fans at Stamford Bridge plus many at their own ground, the ABAX Stadium, watching the Third Round contest on a big screen.
A fleet of coaches took a large proportion of Peterborough's travelling support to West London at mid-morning.
Although Peterborough have lost both their previous FA Cup encounters against Chelsea - conceding five goals on each occasion - followers of the League One promotion chasers are determined to enjoy their day out in West London.
And many have the same hope as the club's Director of Football, Barry Fry- to hold Chelsea to a draw and earn a money-spinning replay at home.
"I've been in football for 56 years and it's the first time I'm going and wanting a draw. I've never wanted a draw. But this one, it would be lovely to get them back at our place."

Peterborough United have completed the loan signing of Rotherham United defender Dominic Ball on a deal until the end of the season.
The 21-year-old started his career at Tottenham Hotspur and spent much of last season out on loan at Rangers.
Ball has been given permission to feature in Sunday's FA Cup tie at Chelsea
It is great to have Dominic at the club. He has good experience, he won the league last year with Glasgow Rangers in a loan spell and we are delighted to have him here.
It is an extra option for us defensively, he can play at centre back, full back or in the holding midfield role, so it is great to have that versatility.
