Peterborough United have signed Grimsby Town centre back Ben Futcher for an undisclosed fee.
The former Oldham Athletic, Lincoln City and Boston United defender arrives at London Road on a three-year contract.
The 25-year-old is reunited with Posh boss Keith Alexander, having played under him at Lincoln.
Posh chairman Barry Fry was pleased to boost the club's back-line with the addition of Futcher.
"Ben Futcher is one of the players that our manager Keith Alexander identified that he wanted on board," Fry told the club's official website.
"I have negotiated long and hard since pre-season for the transfer of Ben Futcher and I am delighted to have reached an agreement with Grimsby before the transfer deadline."
