Inquest records accidental death verdict for jockey Michael O’Sullivan

An inquest has recorded a verdict of accidental death for Cheltenham Festival-winning jockey Michael O’Sullivan, who died after a fall at Thurles racecourse.

The 24-year-old suffered a catastrophic brain injury during a handicap chase in County Tipperary and passed away ten days later at Cork University Hospital on 16 February 2025.

He was highly regarded in the sport, having secured a landmark victory at the 2023 Cheltenham Festival, and was described at the hearing as being towards the pinnacle of his career.

Medical findings confirm severe trauma

Assistant State Pathologist Dr Margaret Bolster conducted the post-mortem examination and shared her findings with the grieving family at the Cork inquest.

She confirmed the young rider sustained multiple skull fractures and died from a catastrophic brain injury complicated by cerebral swelling.

“He would have been deeply comatose and wouldn’t have known anything,” Dr Bolster stated.

First responder describes chaotic final fence

William Sweeney, a cardiac first responder with the Order of Malta, was stationed at the final obstacle when the tragic incident unfolded.

Sweeney noted in his Garda statement that the approaching horses were being heavily pushed down the final straight, prompting him to anticipate trouble.

“The horse had fallen onto the rider, whom I now know to be Michael O’Sullivan, and until it was safely removed it had been on top of him, kicking in panic,” Sweeney recalled.

After the animal was safely moved, Sweeney was instructed by the racecourse medical officer to secure the stricken competitor’s head and cautiously remove his helmet.

Emergency personnel applied pressure to his injuries for approximately 15 minutes before an air ambulance arrived to transport him to hospital.
