Irish jockey Michael O'Sullivan has died after a fall at Thurles on February 6th, the Irish Horseracing Regulatory Board (IHRB) has announced.
O'Sullivan, a Cheltenham Festival-winning jockey, was riding Wee Charlie for trainer Gerard O'Leary and was one of three riders who fell at the final fence in the two-mile Racing Again February 20th Handicap Chase.
The 24-year-old was treated on the track before he was taken by air ambulance to Cork University Hospital where he had been in an induced coma in intensive care.
The rest of the meeting was abandoned.
In a statement, IHRB chief medical officer Dr Jennifer Pugh said: "Michael sadly passed away in the early hours of Sunday morning surrounded by his loving family in Cork University Hospital.
"We extend our appreciation to the multidisciplinary teams who provided the best of medical care to Michael, both on the racecourse and in Cork University Hospital.
"Michael's family would like to reiterate their gratefulness for all the support they have received in the last couple of days and express their appreciation to the local community and racing family. The O'Sullivan family have asked for privacy at this time."
O'Sullivan turned professional in September 2022 and was a rising star in the sport.
He rode 95 winners in Britain and Ireland throughout his career, including steering Marine Nationale and Jazzy Matty to victory at the Cheltenham Festival in 2023.
Sunday's meeting at Punchestown and Irish Point-to-Point fixtures in Knockanard, Nenagh and Tinahely have been cancelled as a mark of respect.
