An event rider is in intensive care at Leeds General Infirmary after breaking his neck at Beckwithshaw Horse Trials (21-22 August).
Experienced rider Robin Donaldson, 64, from Little Ribston near Wetherby, was taking part in the BE100 class.
His mare Matilda Cruz straddled a fence and the retired schoolteacher fell over her neck, landing on his head.
Mr Donaldson’s sister, Liz Kettle, said he has broken two vertebrae in his neck and is paralysed from the neck down.
He is in a critical condition.
“He is a very experienced rider who has evented throughout his life, riding at Burghley in the 80s,” said Ms Kettle.
“Since retirement he has lived for his horses and has two nice youngsters who he was bringing on.
“The medics at the event were marvellous. All we can do now is wait and see.”
A spokesman for British Eventing confirmed that the accident had taken place and said their thoughts were with Mr Donaldson and his family.
