CHELTENHAM, England, March 14 (Reuters) - Jockey Ruby Walsh, the all-time leading rider at the Cheltenham Festival, suffered an arm injury after a heavy fall in the opening race on Gold Cup day on Friday.
The Irishman was catapulted to the turf from the pacesetting Abbyssial at the second flight in the Triumph Hurdle.
He walked off the course clutching his right arm and climbed into a waiting ambulance to be taken to hospital.
Walsh will take no further part at the meeting and will miss the ride on On His Own for trainer Willie Mullins in the showpiece Gold Cup steeplechase (1520).
Walsh has ridden 41 winners at the Festival, including three this year. (Reporting by Justin Palmer, editing by Pritha Sarkar)
