Day two of the St Leger Festival at Doncaster was cast into the shadows after jockey Hayley Turner suffered an awful fall in the Park Hill Stakes.
Turner, 30, was taken to Doncaster Royal Infirmary for further assessment after she was unseated from Seal Of Approval, who clipped heels with Alta Lilea two furlongs from home.
Course officials said Turner was conscious and that she had gone to hospital as a precaution.
She is not thought to have suffered any serious injuries from an appalling-looking accident which drew sharp gasps from the grandstand.
Turner had only just returned to action after she sustained a broken ankle at Yarmouth in July.
Turner's former boss, Michael Bell, was hardly in the mood for celebration after The Lark had won the Group Two Park Hill.
The Lady Bamford-owned filly had finished third in the Epsom Oaks on her penultimate start, but had questions to answer following a meek reverse in France in June.
But a combination of the rain-softened Yorkshire turf and a step up to an extended mile and three-quarters clearly had a galvanising effect on the attractive daughter of Pivotal.
