Unbeaten filly Minhaaj has gained a start in the Golden Slipper after Cellsabeel was scratched.
Cellsabeel, the one-time Slipper favourite, will now be spelled.
Trainer Ciaron Maher said the stable took veterinary advice and the filly would not be fit to run at Rosehill on Saturday.
“This morning we advised the stewards that unfortunately we have made the decision to scratch Cellsabeel from the Golden Slipper,” Maher said in a statement.
“Having completed her final gallop this morning she went to the beach post work. It was clear, having cooled down that she wasn’t 100%.
“ We look forward to giving her a spell and return for the spring.”
It leaves Maher and his co-trainer David Eustace with four runners in the race – Prague, Away Game, Muntaseera and Rathlin.
Cellsabeel is the second scratching from the Slipper with the Chris Waller-trained Global Quest withdrawn on Wednesday giving first emergency Rathlin a start.
Second emergency Minhaaj is unbeaten in two starts including the Group 3 Thoroughbred Breeders Stakes (1200m) at Flemington, where she beat Muntaseera by 4.5 lengths.
Minhaaj is now one of two runners for the Lindsay Park stable with Blue Diamond third placegetter Personal the other.
