Flying Cloud is set for a spell on the sidelines after suffering a setback when winning the Ribblesdale Stakes at Royal Ascot.The Storming Home filly was found to be lame following her four-length romp in the Group Two on her first start for Godolphin."She has had a setback. We will give her time and it will be a little while before we decide what to do with her next," said trainer Saeed bun Suroor.Winner of her only two previous starts when trained in France by Andre Fabre, Flying Cloud had been talked off as a possible opponent for Epsom Oaks heroine Sariska in the Irish equivalent next month.It appears those plans have now been scrapped, and she may not reappear until the autumn, with the Prix Vermeille at Longchamp a possible objective.
