...Callum Hassan following his short spell with the Vanarama National League North club.
Hassan, 22, joined the Bucks in early November following his release from National League side Kidderminster Harriers.
Originally with Hartlepool United, where he made just one first-team appearance, Hassan went on to have relatively brief stays at Workington AFC, Blyth Spartans, Bishop Auckland, West Auckland Town, Billingham Synthonia, Harrogate Town and Harriers, for whom he played three times.
Burton Albion duo Liam Slade and Sam Austin have also returned to the Pirelli Stadium following their loan spells with the Bucks.
