Grand National-winning jockey Ryan Mania has suffered neck and back injuries after falling from his horse at a race at Hexham.

Mania, 23, who celebrated a famous victory after steering 66-1 outsider Auroras Encore to a surprise win at Aintree yesterday, was airlifted to the Royal Victoria Infirmary hospital in Newcastle.

The Scotsman was steering Stagecoach Jasper in the 3.10 St John Lee Handicap Hurdle race at the Northumberland course when he was unseated.

Stagecoach Jasper is believed to have collided with another horse at the first fence on the second circuit. It is feared Mania was then struck by another horse as he lay on the track.

Stagecoach Jasper was also trained by Sue Smith, for whom Mania rode to victory yesterday.

Mania was treated by paramedics at the trackside for over half an hour before being taken to hospital by helicopter. His father is believed to have been with him at the time.

Mania was said to be conscious, and in a stable condition.

His assistant Steve Charlton told the Racing Post: "I think Ryan took a kick between his shoulder blades but he can move all his limbs and is talking."

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."
