Peterborough have agreed a deal for Wrexham centre-back Nathaniel Knight-Percival to move to London Road in the summer.
Knight-Percival has signed a pre-contract agreement and will join Posh once his current deal at Wrexham expires.
The 25-year-old was converted from a winger to a defender by former Dragons boss Dean Saunders at the start of the current Blue Square Bet Premier campaign.
Knight-Percival, a former Histon player, becomes the latest signing recruited from the lower leagues by Peterborough manager Darren Ferguson.
Fellow defender Shaun Brisley and forwards Paul Taylor, Emile Sinclair and Tyrone Barnett have all stepped up to the Championship in the past 13 months.
