Kieren Fallon escaped serious injury after his crashing fall at Royal Ascot on Wednesday.
The champion jockey was the worst sufferer in an accident which took place during the Ascot Stakes.
He was taken under police escort to the Wexham Park Hospital near Slough after suffering an injury to his left shoulder and was detained there overnight.
But Fallon's agent Dave Pollington, said: 'Nothing is broken, though I do not know the extent or detail of his injuries.
'Kieren said that he was feeling pretty unwell, but he that he was up and reading the papers. Beyond that there is nothing than I can report.'
Wednesday's incident was sparked off when Prairie Falcon slipped as the field approached the home bend.
Generosa and Natural Eight were also brought down in the ensuing melee.
Michael Hills, the rider of Prairie Falcon, and Generosa's jockey Alan Daly both hurt their knees.
Seamus Heffernan, the rider of Generosa, was unhurt and all four horses galloped past the post apparently unscathed by the ordeal.
'I'm very stiff and sore,' Hills said. 'The horse fell on its own and I landed on my knees - I think - it happened so quickly. I grazed both knees and then I got kicked on the calf and the arm.'
