Jockey Ryan Mania has been airlifted to hospital after suffering neck and back injuries in a fall at Hexham.
Grand National-winning Ryan Mania, who steered Auroras Encore to a famous 66-1 success at Aintree on Saturday, fell in the 15:10 St John Lee Handicap Hurdle.
Ryan Mania, 23, was riding for National-winning trainer Sue Smith on Stagecoach Jasper.
The Scottish jockey was said to be in a stable condition after being treated by medics for over half an hour before leaving the track.
A spokesman for the Great North Air Ambulance said: “Mr. Mania has received neck and back injuries. He came off the horse at high speed and may have been hit by another horse while he was on the ground.
“He has been given extensive painkillers and is currently in a stable condition. He has been taken to the Royal Victoria Infirmary in Newcastle.”
