The Latics have landed the left-back until January 2 in what is a great boost for the Championship outfit.
Wigan boss Gary Caldwell was thrilled to have competed a temporary deal for Garbutt after losing a pair of key defenders to injury.
"Luke is a tremendous young player with a big future in the game and we are delighted to have reached an agreement to bring him here.
"He knows the division well having spent last season on loan with Fulham and he adds excellent competition to the squad.
"He has great energy, and is a dynamic defender who is comfortable as a wing back or as part of a flat back four."
