The BHA have announced they are sending a vet to examine Altior on Thursday at the stable of his trainer Nicky Henderson, extending the fall-out of his withdrawal from Saturday's Silviniaco Conti Chase at Kempton.
Henderson announced on Tuesday that Altior would not run as he was not happy with the horse. But Altior has not physically been scratched from the race.
That means he could theoretically still run and he remains in the ante-post betting lists of some bookmakers.
