Hayley Turner faces an uncertain spell on the sidelines after suffering a broken ankle in a fall at Bath yesterday.
It was initially thought Turner had escaped serious injury following the incident, where she was unseated on the way to the start.
Turner was going to post aboard Rose Aurora for Marcus Tregoning when the filly appeared to jink in front of the stands rail, rearing up and landing on the dual Group One-winning rider.
Turner was believed to have suffered just bruising, but later went to hospital for X-rays, tweeting: "Ouch!! Im thinking its just badly bruised, on my way to the hospital to double check, gutted I didn't wax my legs before I came racing."
