Chesterfield have signed defender Matty Brown from Evo-Stik Premier League side Marine.
The 23-year-old has agreed a one-year deal with the League Two club after a successful trial spell.
The former Manchester City reserve captain joined Marine from Northwich Victoria in June 2011.
"Chesterfield is a club that's going places, it didn't need to be sold to me and it's a great step in my career," he told the club website.
"I'm delighted to have signed for Chesterfield and I can't wait to get going."
Brown is the second player to join the Spireites this week after former Hartlepool full-back Ritchie Humphreys signed a one-year contract on Monday.
