Gary Stevens sustained a collapsed lung in his dramatic fall just after the line from Storming Home in the Arlington Million on Saturday.
The jockey is still in Chicago´s North Shore Hospital but has broken no bones and is hopeful of getting back in the saddle soon.
Storming Home, who was first past the post, was disqualified and placed fourth for interference close to the finish with Godolphin´s Sulamani awarded the race.
