Jimmy Ryan has had his contract extended until the end of next season following the activation of a clause in his agreement.When the midfielder joined the Spireites in the summer on an initial 12-month deal, it was agreed that he would be rewarded with a contract extension after making a set number of appearances.
Manager Paul Cook is pleased to have secured the 25-year-old to a longer agreement. He said: "We are all delighted with Jimmy's contribution and I know he's very happy here so I think it's a perfect fit."
Ryan, who has scored two goals in 26 league and cup appearances this season, signed for Chesterfield after coming to the end of his contract at Scunthorpe United. He previously played for Accrington Stanley and Shrewsbury Town after being at Liverpool as a youngster.
Meanwhile, Cook has thanked Gary McSheffrey for the contribution he made during a four-month stint at the Proact after deciding against offering the player an extended deal. "I'd like to thank Gary for his services and wish him well for the future," said Cook.
McSheffrey, who scored two goals in 12 appearances for the Spireites, has subsequently signed for Scunthorpe United.
