Arzal out of County Hurdle Arzal has been ruled out of the Vincent O'Brien County Handicap Hurdle at Cheltenham on Friday. The Harry Whittington-trained five-year-old suffered a knock when making a mistake early on in the Imperial Cup at Sandown on Saturday. "He won't be running on Friday," said Whittington. "He picked up a problem at the second hurdle and that was why he ran a disappointing race."
