Burnley defender Daniel Lafferty has agreed to extend his loan spell at Rotherham until the end of the season.
Borussia Dortmund defender Mats Hummels has denied making any promise to join Manchester United.
MK Dons have signed teenage Wolves winger Zeli Ismail on loan until January 2.
The two clubs were able to conclude a deal on the stroke of Thursday's 5pm emergency deadline.
The delay led to the Football League only being able to ratify the move on Friday afternoon.
Ismail, 18, came through the youth ranks at Molineux before signing a first professional contract in 2010.
He made his first senior appearance for the club in September this year, coming on as a substitute in the Capital One Cup defeat to Chelsea.
The former England Under-17 international goes straight into the Dons squad for Saturday's match against Colchester.
