Helen Mercer had to be cut free from a friend's Peugeot 206 after climbing inside to recover from a previous fall during a show jumping event at Misty Blue Farm at Spennymoor, County Durham.
The 26-year-old rider refused first aid after she took a tumble when her horse failed to make a jump. She was taken to the Peugeot to recover but was later cut free as it became apparent she may have suffered serious spinal injuries.
> The Yorkshire Air Ambulance was called to the scene but firefighters had to be roped in when the extent of her injuries were discovered.
The team of firefighters had to use specialist equipment to remove the doors of the small hatchback and peel back the roof so Ms Mercer could be removed on a spinal board.
She was taken to the University Hospital of North Durham and it is understood she was discharged having suffered cracked ribs at Sunday's event.
The Daily Mail reported that she later took to Facebook to say: "Just to let everyone concerned know I am fine, few cracked ribs soft tissue damage bruised lung and spleen but otherwise fine."
It is understood Ms Mercer wasn't wearing any body armour during the event and onlookers said she was very lucky not to suffer more serious injuries.
