Racing: Johnny Murtagh will ride hot favourite Dylan Thomas in the King George VI And Queen Elizabeth Stakes at Ascot on Saturday.
Murtagh has not linked up with the colt since the combination finished third to Sir Percy in last year's Vodafone Derby.
It will also be the 11th consecutive jockey change for the Aidan O'Brien-trained four-year-old.
The Ballydoyle handler told the Racing Post: "We've booked Johnny for Dylan Thomas and Mick (Kinane) will again ride Scorpion.
"At this stage it's unlikely Yellowstone will run."
