Northampton Town left sided player George Smith has signed for Sky Bet League 2 side Chesterfield for an undisclosed fee.
"We were contacted late on deadline day by Chesterfield," said manager Jimmy Floyd Hasselbaink.
"We weighed up the options and felt this was a good move for all parties.
"We have a lot of competition for places down the left hand side and some of the recent arrivals have added to our strength in that area.
"For George himself, it will give him the chance to play regular first team football and will benefit him.
"George has a fantastic attitude and we wish him well at his new club."
The paperwork was completed right on deadline and the move is subject to ratification of the registration by the EFL.
