Nicky Adams has left the Cobblers and joined Sky Bet League Two outfit Carlisle United on a free transfer.
The attacking midfielder will officially become a Carlisle player from July 1, with the player asking for the move as he is keen to be closer to his family which is based in the north west of England.
Adams, who signed for the Cobblers on a three-year deal from Bury a year ago, was a key player in Town’s league two title-winning season.
Cobblers manager Rob Page said: “We wish Nicky well.
“He had already requested the opportunity to move back nearer to his family before my arrival, and after further discussion we felt it was the right thing.
“Nicky certainly played a role in the club’s success last season and I am sure he will go with the best wishes and thanks of all supporters.”
Adams, who also helped Bury win promotion from league two in 2014/15, made 39 starts and six substitute appearances for the Cobblers, scoring three goals.
Two of those came in the final few games of the season against Bristol Rovers and Yeovil Town.
The 29-year-old was a popular member of the Cobblers squad, and was right at the top of the league two charts for assists last season.
Meanwhile, the Cobblers have announced that 17-year-old Academy product Shaun McWilliams has signed the two-year professional contract offered to him last week.
The combative central midfielder, who hails from Kings Heath in Northampton, has been with the since the under 14 age-group.
“All of us in the Academy are delighted that Shaun has signed his deal,” said Academy manager Trevor Gould.
“It takes a lot of hard work from many people over a number of years to help a talented 14-year-old player become a professional footballer, and a lot of credit is due to Shaun, his family and the staff in the Academy.
“Shaun is a very level headed young man and he knows the hard work starts now, but this is a fantastic boost for everyone in the Academy and for young Northampton footballers in general.
“He is joining a very talented first team squad and we wish him every success.”
