After incurring a small setback, the Mouse Morris trained China Rock has been withdrawn from the Hennessy Gold Cup at Newbury on Saturday.
Although well backed since the announcement that jockey Barry Geraghty would be aboard for the ride, the trainer has now confirmed his charge will not take part in the prestigious event.
"I had to make a final decision this morning and I just wasn't 100% happy with him," said Morris.
"He would have had to travel today and I wasn't happy for him to do that.
"It's not a season-ending injury or anything like that, he's just going to have to miss this one.
"I hope he'll be all right to run at Christmas, probably in the Lexus Chase at Leopardstown."
