Northampton Town boss Aidy Bothroyd has confirmed that the club have withdrawn their contract offer for Nathan Cameron.
The 21-year-old had been on trial at the club after leaving Coventry City, with Bothroyd reportedly offering the defender a permanent contract.
However, Bothroyd has now told the club's official website: "There comes a time when you have to move on. In this instance we have moved on and that door is now closed."
A number of Football League clubs are believed to be interested in his signature.
