Irish jockey Andrew Thornton is expected to be back in action later this week after escaping with just soft tissue damage when riding Donatis Comet at the Curragh on Monday.
The Irish Grand National-winning rider thought he might have suffered a fracture during the Keadeen Hotel Wedding Specialists Handicap.
The 10-furlong handicap was delayed when several stalls failed to open which resulted in a false start.
Thornton finished fifth on the Pat Martin-trained six-year-old but was unable to ride out Donatis Comet after feeling some pain in the closing stages.
Thornton went to hospital for X-rays, which revealed no break.
"Andrew's fine, no fracture of the fibula," said Dr Adrian McGoldrick, the Irish Turf Club's chief medical officer.
"It's just a soft tissue injury. He's just stood down for a day or two, but he's fine.
"He had an X-ray on the way home which showed no fracture."
