Aidan O'Brien admits his son Joseph was lucky to escape serious injury after parting company with the ill-fated Furner's Green in Sunday's French 2000 Guineas at Longchamp.
The three-year-old flew home under the young rider to claim third in the Poule D'Essai Des Poulains, but broke a leg shortly after the line.
"It could all have ended in disaster in the French Guineas on Sunday when Furner's Green took a fatal fall passing the winning post," said the trainer.
"We were all so very sad for the horse, but Joseph was so very lucky. If it had happened a furlong earlier three or four horses could easily have trampled all over him, and he could have been seriously hurt as they were travelling flat out."
