United have completed the signing of Scott Wiseman on a free transfer from Preston North End.
The former England U20 and Gibraltar international pens a two year deal at Glanford Park.
Wiseman can play anywhere across the back four and has Championship experience with Barnsley.
Wiseman becomes the second Preston player to join this week- following the arrival of utility man Jack King.
Last season, he made 35 appearances in all competitions, scoring twice, as Preston won promotion to the Championship.
