Ruby Walsh will miss the rest of the Cheltenham Festival after he broke his arm in the first race of the day.
Walsh fell off Abbyssial at the first fence and was taken straight to hospital, where doctors confirmed an arm fracture.
Walsh was leading the field over the second hurdle when taking a crunching spill, bringing down stablemate Adriana Des Mottes in the process.
Walsh was able to walk gingerly to the ambulance, but could be seen holding his arm.
The rider was set to undergo surgery on the open fracture at Gloucester Hospital.
A racecourse spokesperson said: "He has a compound fracture of his right humerus. He has been taken to Gloucester for surgery."
