Grand National winning jockey Ryan Mania will be kept in hospital for a further 24 hours.

It was expected that he would be released today, after being airlifted to hospital in Newcastle following a fall at Hexham yesterday.

He suffered injuries to his neck and back but was able to tweet from hospital:

Thanks so much for all the messages. I'm grand. Staying in hospital to get another scan tomorrow then should be home. #highsandlows
