Champion jockey Tony McCoy was taken to hospital for further examination on a chest injury after suffering a heavy fall at Cheltenham.
The Co Antrim man was partnering the Nicky Henderson-trained Quantitativeeasing in the Barbury International Horse Trials Handicap Hurdle when the gelding stumbled at the second flight, throwing McCoy into the air.
While he was conscious after the fall, he had to be stretchered off the track and was given oxygen on his way to the medical room by ambulance.
Following assessment at the track, McCoy was taken to Gloucestershire Royal Hospital for further checks.
Cheltenham communications manager Andy Clifton said: "He has suffered a chest injury, but he is conscious and moving all his extremities.
"He has been transferred to Gloucestershire Royal Hospital for further assessment."
