Lincoln manager Steve Tilson has extended Julian Kelly's loan spell from Reading until the middle of April.
The defender, who has made eight appearances for the Imps since arriving from the Championship club, will remain at Sincil Bank until April 16.
However, there is a recall clause in the 21-year-old's new deal.
Kelly has featured in several positions during his first month with Tilson's side.
He is currently recovering from a thigh injury that forced him to miss the midweek draw at Aldershot.
