Australian equestrian champion Heath Ryan is recovering in hospital after suffering a stroke while competing at an event in Camden, southwest of Sydney, on the weekend.
A spokesperson for Campbelltown Hospital said he was in a stable condition.
Brother of triple Olympic gold medallist Matt Ryan, Heath had recently returned from an international competition in Las Vegas.
The 50 year-old, from the Hunter Valley in NSW, had competed at last year's Olympics in Beijing where he had a best result of eighth as part of the teams event.
Prior to that Ryan had been assistant coach with the Australian equestrian team at the Atlanta, Sydney and Athens Olympics.
