Jockey Mark Walsh was stood down on the second day of the Cheltenham Festival after he suffered a fall in the opening race on the card.
Walsh was partnering Consul De Thaix in the Neptune Investment Management Novices' Hurdle when the horse sustained a fatal fall at the sixth-last flight.
Consul De Thaix is trained by Nicky Henderson and owned by JP McManus, for whom Walsh is a retained jockey.
Walsh was due to partner Hargam in the Coral Cup and Cantlow in the Glenfarclas Chase.
Clerk of the course Simon Claisse said of Walsh: "The last information I received was that he was being assessed for a concussive head injury."
