Henderson update on his stars Nicky Henderson reported Simonsig scoped dirty after winning the Racing Post Arkle at Cheltenham while Oscar Whisky was "a bit lame" following his Ladbrokes World Hurdle flop. Simonsig won the two-mile novice chase despite taking a fierce hold through the race and making a couple of mistakes. "I don't think you saw the proper Simonsig at Cheltenham, we'll have a look at him," Henderson said. "He seemed to be running away from something and his scope was not quite right after the race. It's as well we didn't scope him before as I wouldn't have run him." There could also be an issue with Oscar Whisky, who was pulled-up as favourite for Thursday's showpiece. "He was a bit lame, but I've not found anything dramatic," said Henderson. Sprinter Sacre, who ran away with the Queen Mother Champion Chase will head to Punchestown and there will be further outings in the spring for Supreme runner-up My Tent Or Yours and Riverside Theatre, who stayed on for fourth in the defence of his Ryanair crown. "I'd say Riverside Theatre ought to run again and whatever he does ought to begin with a three," Henderson said.
