Dan Gardner has signed a 12-month contract extension which ties him to the club until the summer of 2016.
The 24-year-old forward impressed after signing from FC Halifax Town in January - scoring three goals in 11 appearances - and he is delighted to have strengthened his commitment to the club.
"It means a lot because I'm enjoying my time at the club and playing some of my best football here," Gardner told Spireites Player. "I'll work hard and try and cement my place in the team to help Chesterfield push on from last season."
Gardner believes the Spireites are well equipped to cope with the demands of playing in Sky Bet League 1. He said: "It's going to be hard but we've got the management team and the players in place and the way we play will suit us in a higher division. It'll be good to test ourselves against some big teams who have come down from the Championship."
With the pre-season programme starting with a game at Buxton on Saturday week, Gardner has been preparing himself for the hard work that lies ahead. He added: "I've been doing some hills runs and gym work. I'm looking forward to my first proper pre-season in a way but I know that 'Shinner' (Shane Nicholson) is a bit of a fitness freak!"
Gardner is the second player in the space of a week to sign a contract extension after Sam Morsy agreed a similar deal.
