Davy Russell was taken to hospital for X-rays on a leg injury following a fall at Roscommon on Tuesday evening.
The rider parted company with the Gordon Elliott-trained Crack Of Thunder four fences from home in the Michael Holland Tyres Handicap Chase.
Medical officer Dr Richard Downey said the rider had gone to Tullamore Hospital with a "query tibia fracture" but Russell tweeted later that evening that he had broken no bones and was just "badly bruised".
