Simeon to be supplemented for French Derby

The Mark Johnston-trained Simeon is to be supplemented for the Prix du Jockey Club, the French Derby, at a cost of €60,000 on Thursday.

Frankie Dettori, who won the race 10 years ago on Polytain, will partner the Jumeirah Racing-owned colt for the first time in the classic at Chantilly on Sunday.
