Jockey Michael O'Sullivan has died following a fall at Thurles last week.
In a statement, the Irish Horse Racing Regulatory Board said he died in the early hours of this morning.
Racing was abandoned in Thurles on February 6th due to the final-fence fall during which Mr O'Sullivan was one of three fallers.
Mr O'Sullivan, 24, had been in intensive care in Cork University Hospital since the incident.
The CEO of the Irish Horse Racing Regulatory Board, Darragh O'Loughlin, paid tribute to Mr O'Sullivan, describing him as an "exceptionally talented young rider".
"Michael will be deeply missed by everyone in racing who had the pleasure of knowing him," he said.
The Chief Medical Officer of the IHRB, Dr Jennifer Pugh, also paid tribute to Mr O'Sullivan saying that his "dedication, modesty and kind nature always made him a pleasure to be around.
"Michael's success and his humility will have inspired many and I share the feeling of loss today with all those who knew him," she said.
Dr Pugh said that Mr O'Sullivan's family would like to reiterate their gratitude for the support they received and express their appreciation to the local and racing community.
In all, O'Sullivan rode 90 winners in Ireland and five in Britain under rules, with his most recent big-race success coming aboard Embassy Gardens for champion trainer Willie Mullins in the Grade Three New Year's Day Chase at Tramore.
The IHRB said that as a mark of respect, the fixture at Punchestown and the Point to Point fixtures have been cancelled.
May Michael rest in peace.
