Likely outsider Shamkala was the only horse to drop out of the field for Sunday's Prix de l'Arc de Triomphe at the latest forfeit stage on Wednesday.

The Aga Khan's filly had lost her way since a bright start, but still leaves 19 possible runners headed by defending champion Treve, and leading contenders such as Just A Way, Taghrooda and Ectot.

There is still a final chance to supplement for the Longchamp showdown, at a cost of €120,000 on Thursday.
