Jockey Freddie Tylicki is in the major trauma unit at St George's Hospital in Tooting after falling off his horse at Kempton. The German-born flat racer was injured in an incident that also involved champion jockey Jim Crowley, who has been discharged from hospital.
Tylicki, 30, was taken by air ambulance to the hospital with suspected spinal injuries, while the meeting at Kempton was abandoned in light of the fall. Action replays of the crash appeared to suggest it was caused by Tylicki's horse, Nellie Dean, clipping heels with Madame Butterfly, the leader and eventual winner of the race.
"Freddie Tylicki is in intensive care in a stable condition. He is conscious and there will be a further update tomorrow once more is known," a statement from the Injured Jockeys' Fund confirmed.
The body added that Crowley had already been discharged "to return home with his family".
Two other jockeys, Steve Drowne and Ted Durcan, were also thrown from their horses in the third race of the afternoon at Kempton as the field rounded the home turn. However, they were both able to walk back to the weighing room and were not found to have any serious injuries.
None of the horses involved in the fall are reported to have sustained any serious injuries.
