Snow Leopardess has been ruled out for the rest of the season after suffering a setback.
The Charlie Longsdon-trained mare faces a spell on the sidelines after sustaining a leg injury following her comeback run at Auteuil in September.
The five-year-old won three of her five starts last season, culminating with a Grade Two victory at Newbury in March.
Longsdon said: "She has unfortunately picked up an injury after her race in France. We had a fair idea after the race, we gave her time but it was obvious she was not going to recover soon, so you won't see her on track for the rest of the season.
"It is very disappointing and gutting as there was no doubt she would have been up there in all the good mares' races.
"She was a great hope for this season and she is still very untapped in terms of potential. Hopefully we will see her back next season."
