The next race was delayed by 10 minutes while he received treatment on course.
“I have spoken to the doctors that treated him on track and he has gone to hospital in Brighton for precautionary X-rays. He was conscious,” said clerk of the course, Philip Hide.
Twiston-Davies was hurt after being unshipped from Master Burbidge at the second fence in the Download The At The Races App Handicap Chase.
