Keith Briggs has been left in limbo after Mansfield changed their offer of a new contract for the defender.
The 26-year-old had all-but agreed fresh terms under former Stags boss Paul Holland, but his departure has thrown Briggs' future up into the air.
New Mansfield boss Billy McEwan has informed Briggs that the club cannot afford to offer the defender the contract that was initially on the table and that he would have to try and win a new deal at Field Mill.
Briggs has been forced to reject the new offer on substantially reduced terms and is now on the lookout for a new club.
The player's agent,Jesse Learoyd-Hill, admitted Briggs was unhappy at the U-turn over the contract offer by Mansfield.
"We are naturally disappointed that the situation has changed so drastically," Learoyd-Hill told skysports.com.
"We had commited with the previous manager, Paul Holland, to help the club get straight back in the League and the terms had been agreed.
"However, the circumstances have altered dramatically. At 26, a former Norwich player and Stockport captain, Keith is not a young apprentice.
"We will now be speaking with other league clubs who recognise Keith's undoubted quality and experience."
