Ivan Toney has signed a three-year professional contract at Cobblers.
The 17-year-old striker is a product of the club’s academy and has broken into the first-team squad this season.
Toney become the youngest player ever to represent Cobblers when he made is debut as a substitute against Bradford City in the FA Cup last season.
And boss Aidy Boothroyd is delighted with the young frontman’s development.
“Ivan has progressed really well,” said Boothroyd.
“He might not quite be ready for a run of games in the first team just yet, but he has made big strides and we wanted to get his future tied down.
“He is another product of our academy and Trevor Gould and his staff deserve a lot of credit for the increasing number of young players emerging from our academy.
“Ivan can be really pleased with what he has done so far, but the challenge for him now is to kick on again. We will push him and work hard with him but he has all the natural ingredients a striker needs.
“This season he has got himself ahead of some older players in the pecking order and it is great news that he is tied down to June 2016.”
