Chesterfield's highly-rated striker Jamie Ward has turned down a new deal at Saltergate.
The 22-year-old's current contract expires at the end of the season and Chesterfield were keen to tie him down to a new long-term deal.
Ward's performances have attracted the interest of several Championship clubs and Spireites manager Lee Richardson is resigned to losing the former Aston Villa trainee.
"We're aware that Jamie is ambitious and had hoped he'd sign a new improved contract, which in fairness would have included a get-out clause should a higher-level club have made an acceptable offer for him in the future," Richardson told the club's official website.
"For the moment the negotiations have ended so we get on with the football, which is what it's all about.
"There's been speculation about interest from other clubs but the situation is now very much in Chesterfield's court because the player won't be going anywhere this season unless the deal's acceptable to the football club."
