All bar one of the entries for Sunday's Prix de l'Arc de Triomphe stood their ground at the latest forfeit stage.

The sole withdrawal was the German-trained Iniciar, which leaves a total of 20 possibles ahead of Thursday's supplementary stage.

Criquette Head-Maarek's Treve and the Aidan O'Brien-trained St Leger winner Leading Light are expected to be added to the field while connections of Meandre could also pay the €100,000 fee to join the Arc line-up.

Final declarations for the race will be made on Friday morning.  

Ahead of the feature event, Frankie Dettori will have to prove his fitness in time to ride Treve.

The jockey was unshipped from Eland Ally prior to the Handicap and was unable to put any weight on his right ankle as he attempted to get to his feet.

Dettori returned to the Nottingham medical room in a wheelchair and was stood down for the rest of the day.

Course doctor Chris Reynolds initially suggested the rider had suffered a sprained ankle and that it was "definitely a possibility" he could make a full recovery by the weekend.

However, Reynolds later confirmed the jockey had gone to hospital for precautionary X-rays.

He said: "He has now gone for a precautionary X-ray in Newmarket."

Dettori rode the Criquette Head-Maarek-trained Treve for the first time in competitive action in last month's Prix Vermeille.

The filly is a best-priced 9-2 second favourite for the Arc.
