Rangers assistant boss McCoist was part of the team which suffered one of the biggest upsets in Scottish Cup history when part-time Accies won 1-0 in a third-round clash at Ibrox.
Sprott was the unlikely hero for the visitors, ending goalkeeper Chris Woods' British record-breaking run of 1,196 minutes without conceding a goal, and his name will never be forgotten by Hamilton fans - or McCoist.
The 46-year-old former striker will take charge of Rangers on Sunday - as is Walter Smith's wont in all domestic cup ties - and is desperate to avoid a repeat in what is the sides' first Scottish Cup meeting at Ibrox since that fateful day.
"You don't have to look very far to motivate the lads ahead of this one, do you?" said McCoist, looking ahead to the quarter-final.
