Karaktar is one of the star names among 18 horses still in contention for the Prix du Jockey Club following the first forfeit stage.
The Aga Khan’s colt has made a flying start to his three-year-old career, winning a Saint-Cloud Listed prize by upwards of seven lengths before an impressive display in a Group Three contest at Longchamp last month.
The Aga Khan's racing manager Georges Rimaud is looking forward to seeing the youngster test his powers in Classic company at Chantilly on Sunday.
He said: "He worked (on Tuesday morning) and so far all the lights are green, so hopefully he can run at Chantilly.
"The draw is an always an issue, but that is in the hands of the gods.
"There is nothing we can do about it, so you wait until after the draw and make a plan to deal with it at the last minute.
"It will be interesting to see how he goes against better competition and in a bigger field."
Karaktar is likely to be trainer Alain de Royer-Dupre's sole contender for the mile-and-a-quarter contest as he bids to win the race for a seventh time.
Aidan O'Brien has never won the race known to some as the French Derby and has four possible contenders in Cape Clear Island, Highland Reel, War Envoy and Sir Isaac Newton, who runs at Gowran on Wednesday.
Andre Fabre has Harlem and New Bay in the field, while other contenders include Prix Greffulhe winner Sumbal, who is also in contention for the Investec Derby at Epsom.
