Davy Russell has been taken to hospital after suffering a suspected broken arm and leg in a fall at Gowran on Saturday.
Russell was aboard front-runner Feenakilmeedy in the Brian Cody & www.aclsurgery.ie Mares Beginners Chase when the pair crashed out at the third-last fence.
Shuilamach was also brought down in the incident while Shaunas Dream was another to come to grief at the same obstacle.
Clerk of the course Paddy Graffin reports Russell to have been taken to St Luke's Hospital in Kilkenny with suspected fractures to his humerus (upper arm) and tibia (lower leg)
Graffin said: "Bascially it was Davy who brought down the other horse (Shuilamach) and he took the full brunt of a horse travelling at over 30 miles an hour.
"He's fully concious and has been taken to St Luke's Accident and Emergency with a suspected broken arm and leg."
Russell had confirmed earlier in the day that he had lost the ride on 2014 Cheltenham Gold Cup winner Lord Windermere following his lacklustre defence of his Festival crown.
The dual Irish champion partnered the Jim Culloty-trained runner to a famous success in the Cheltenham feature last term, but he was eventually pulled up with two fences still to jump in last week's renewal.
The nine-year-old was in the rear throughout and tailed off when Russell eventually called time, with the rider reporting Culloty to be unhappy with his efforts in the saddle.
Russell told the Irish Daily Star: "It's very disappointing to lose the ride on Lord Windermere. I'll never forget last year's Gold Cup win on the horse which was one of the highlights of my career.
"After the Gold Cup Jim told me he didn't want me riding his horses.
"He wasn't happy with the ride I gave the horse (Lord Windermere) and he said he wanted a change."
