Ballydoyle horses out of Prix de l'Arc de Triomphe, stable announce
Aidan O'Brien's Ballydoyle stable: 'Unfortunately the results of the urine samples taken from the horses have come back positive from the French laboratory'
Ballydoyle have withdrawn their horses for this Sunday's Prix de l'Arc de Triomphe, as well as all races at the meeting in France, the stable have confirmed.
It emerged yesterday that doubt had been cast on the participation of Aidan O'Brien's runners in Sunday's Arc at Longchamp due to batches of Gain Feeds' products being contaminated with a prohibited substance.
