Northampton Town pair David Buchanan and Luke Coddington have agreed to join the Spireites when their contracts expire at the end of the month.
Buchanan is a 33-year-old left-back while 24-year-old Coddington is a goalkeeper who started his career in Middlesbrough’s academy and represented England at Under-19 level. They have both agreed two-year contracts, effective from July 1.
Buchanan has made over 550 senior appearances in a career which saw him play for Preston North End, Tranmere Rovers, Hamilton Academical and Bury before signing for Northampton in 2015. He was also capped 15 times by Northern Ireland at Under-21 level.
"I'm glad it's all done and dusted now and I can't wait to get started," said Buchanan. "I'm someone who gives nothing but 100 per cent every time I put the shirt on."
Coddington joined Huddersfield Town after leaving Boro before signing for Northampton in 2017. He has had several loan spells, including two stints at Wrexham.
Coddington said: "It happened quite quickly and as soon as I heard Chesterfield were interested, I wanted to come here. The stadium and the facilities are brilliant."
