Due to the defection of Fascinating Rock Frankie Dettori will take the ride on Aiden O’Brien’s Order of St. George.
The four times Arc winner Frankie will be looking to add another on this Royal Ascot winner.
The horse was beaten at long odds on in the Irish St. Leger but will be trying the mile and a half distance for the first time on Sunday.
It is no secret that Aiden O’ Brien has had this race in mind for his charge and he looks well made as he stays longer than the trip.
Frankie said "I was getting a bit anxious that I might miss out on an Arc ride after Fascinating Rock failed to make the race so I am delighted that Aidan has asked me to ride for him again.
O’Brien also has Highland Reel and Found in the race and has a good hand.
Postponed is still the solid favourite for the race but Harzand looks certain to take his place in the starting line-up. Makahiki looks an interesting prospect for the Japanese who would love to win this race.
