Grimsby Town have signed striker Andy Cook from Blue Square Bet Premier rivals Barrow.
The 21-year-old has agreed a two-year contract at Blundell Park, with an option to extend it.
Because he is under 23, the two clubs are now negotiating over a fee, or the matter will have to be settled by an Football Association tribunal.
He scored 17 goals in 39 games for Barrow last season, including a hat-trick against champions Fleetwood.
Cook began his career with Carlisle United but loan spells with Workington and Barrow followed before he joined the latter permanently in January 2011.
