Tapestry has emerged a possible challenger for the Prix de l'Arc de Triomphe after French racing authority France Galop said she could be supplemented for the race.
The addition of Aidan O'Brien's filly, who lowered the colours of Arc ante-post favourite Taghrooda in the Yorkshire Oaks in August, is likely to pave the way for Ryan Moore to take the mount at Longchamp on Sunday.
France Galop tweeted last night: "The possible supplementation of Tapestry would allow Ryan Moore to maybe ride in the Arc."
The final chance to supplement for the Arc is today, when the filly's powerful connections must pay E120,000 to add her to the field.
Despite having claimed the scalp of Taghrooda on her penultimate start, Tapestry will be sent to France on a redemption mission following a subdued run in the Matron Stakes at Leopardstown last month, when she finished ninth.
Another piece of the Arc jigsaw slotted into place earlier in the day when Frankie Dettori was confirmed as the rider of the O'Brien-trained Ruler Of The World.
It had been feared the Italian, who missed the winning mount on Treve 12 months ago at Longchamp and has been replaced on the filly by Thierry Jarnet, would be forced to watch from the sidelines once again this Sunday.
There was speculation over which jockey would get the nod on O'Brien's 2013 Investec Derby hero, although three-times Arc winner Dettori had been in the saddle when he registered his victory in the Prix Foy.
Al Shaqab Racing, which retains Dettori, is a part-owner of the Galileo colt along with the Coolmore partners, and O'Brien's son, Joseph, had ridden him on his previous start in the Dubai World Cup.
Dettori's agent, Ray Cochrane, said: "Frankie told me this afternoon he's riding the horse, and hopefully he'll have plenty more rides through the day."
O'Brien is also due to represented by Chicquita, the intended mount of the trainer's son, Joseph.
