Nina Carberry is set to miss several weeks of action and almost certainly the Cheltenham Open meeting after breaking her collarbone.
The leading amateur rider was involved in a nasty incident at Punchestown on Wednesday when her mount Northern Command was one of four horses brought down.
It was caused by Superior Ben slipping and his rider Paddy Kennedy has a suspected fracture of his left leg.
Carberry's agent Shane Lyons said: "The collarbone is broken, so I should think she will be out for the best part of three weeks."
Meanwhile, Ruby Walsh was seen at his brilliant best when recording a shock victory aboard For A Song in the featured Wilderness Chase.
The Leslie Young-trained gelding was sent off at 16 to 1 and made virtually all before just holding on by a head from Letterman.
"His future will depend on what the handicapper makes of this. He's a super jumper for his size and Ruby riding him was a big bonus," said Young, who is considering a trip to the upcoming Cheltenham meeting.
Davy Russell is still three ahead of Walsh in the title race having earlier moved on to the 71-winner mark for the season after Migmatite landed the four-year-old maiden hurdle.
Horse Racing Ireland (HRI) have announced Paul Finegan is to become manager of its betting division. Previously Finegan was general manager for Irish Racing Services.
