Jockey Rachael Blackmore is in "good spirits" after undergoing surgery following a fall that saw her suffer a fractured ankle and hip injury at Killarney on Friday.
The Grand National-winning rider, who had had earlier won two races on the fifth and final day of the meeting, was injured when favourite Merry Poppins fell in the handicap hurdle.
The 32-year-old was attended to on track by medics for almost half an hour before being moved into an ambulance.
The Irish Horseracing Regulatory Board's senior medical officer, Jennifer Pugh, issued an update on Saturday morning, which read: "Rachael Blackmore sustained a fractured ankle and hip injury following her fall in Killarney on Friday evening.
"She has had surgery overnight and is in good spirits this morning."
