Jack Lester: Chesterfield striker to retire at the end of the season
Chesterfield striker Jack Lester has announced he is to retire after Saturday's match against Exeter City.
The 37-year-old former Grimsby, Nottingham Forest and Sheffield United player will captain the Spireites against the Grecians.
The League Two side revealed in March that they would not be extending his deal beyond this season.
Lester has nine goals so far this season and has 83 League goals in 196 league appearances for Chesterfield.
He told the club website: "I've decided to retire from football in the summer, which has been a tough decision. I've got some opportunities coming up to observe coaching around the world.
"I'll get an insight into some international sports psychologists, using their expertise. I'm also doing some coaching in America.
"I've got a year before my son starts school, which is why I've decided to retire and make the most of the opportunities that are there."
Manager Paul Cook added: "There's no doubt Jack will go down as a Chesterfield legend. He's been a fantastic servant to this club.
"Jack's leading the side out against Exeter and I hope it's a special day for him. I'd love him to be able to sign off with a goal in front of the Kop and then see everyone give him the send off that he deserves. I wish him every success for the future."
