CHELTENHAM, England (AP) -- Irish jockey Ruby Walsh withdrew from the Gold Cup after being taken to hospital with a broken arm following a fall in the JCB Triumph Hurdle at the Cheltenham Festival on Friday.
A second jockey, Daryl Jacob, also fell and was carried away on a stretcher. His injuries were not known.
Riding Abbyssial for Willie Mullins, Walsh was thrown at the first fence and walked to an ambulance holding his right arm. He was the joint-leading rider at the start of the festival's final day with three wins.
''He has a compound fracture of his right humerus. He has been taken to Gloucester for surgery,'' a racecourse spokesperson said.
Jacob's mount Port Melon crashed into a rail before the Albert Bartlett Novices' Hurdle, throwing Jacob into a spectator area. Jacob, who was reportedly conscious, received medical treatment before being taken away. He had just won the preceding race on Lac Fontana.
