Bolton Wanderers could lose several players
Bolton Wanderers face losing a number of key players after several members of the squad rejected the club's initial offer of new deals, HITC Sport understands from sources close to the club.
Bolton secured promotion back to the Championship from League One this season after finishing second to Sheffield United in the table.
However, their plans next season could be thrown into disarray after failing to agree fresh terms with a number of the promotion-winning squad.
The likes of David Wheater, Gary Madine, Filip Morais and Jem Karacan are all out of contract at the Macron Stadium next month and they have turned down the club's initial offer of new deals.
Bolton Wanderers manager Phil Parkinson celebrates promotion with the trophy
Adam Le Fondre, who ended last season on loan at Bolton, is a free agent this summer after leaving Cardiff and he has so far rejected Bolton's offer of a contract to join the club on a permanent basis.
The news of the contract wrangle with several stars will come as a major concern for Trotters boss Phil Parkinson as he looks to keep hold of his best players and plan ahead for next season in the Championship.
