Dublin-born Keegan, who is a former Eire youth international, is expected to be on the sub's bench for tonight's Third Division game at Carlisle.
It is thought he will gain valuable experience with the injury-hit Iron.
Another Keegan, Kevin, was famously associated with Scunthorpe many years ago, before getting international acclaim with Liverpool and England.
It could be a good omen for the youngster.....and Leeds.
