British rider Emily Gilruth is in intensive care after falling during the cross-country phase of this year's Mitsubishi Motors Badminton Horse Trials.
She first competed at Badminton previous year and has competed on Topwood Beau - who was uninjured - since 2008.
Emily's family would like to thank all the many well-wishers for the lovely supportive messages that they have received.
In a statement, Badminton's chief medical officer Dr Sue Smith said: "Emily remains in intensive care at Southmead Hospital, Bristol, undergoing treatment and further investigation". She has had a stable night and remains under sedation.
Topwood Beau, a 14-year-old gelding, was uninjured in the fall, which happened at the Keepers Question obstacle.
Ms Gilruth has competed in British event competitions for 18 years and first competed at Badminton last year.
