A Royal Ascot-winning jockey has told how he had to retire at the age of 25 after suffering post traumatic stress disorder following a heavy fall.

George Chaloner had just returned from injury when his horse Woodacre fractured a leg and he was thrown to the ground.

Just millimetres from paralysis, he broke a vertebrae and his foot. He now suffers flashbacks and says that he will never ride again.

Mr Chaloner cannot remember getting on the horse or riding the race, saying: "All I remember is horses going over the top of me and then waking up in hospital."

"Being in hospital laid on my back in a brace I just thought someone was trying to tell me something. It stopped my career, it stopped the only thing I ever knew.

"Being told I was half a centimetre from being paralysed - it was a big shock."
