Samcro will miss the Lawlor's Of Naas Novice Hurdle on Sunday after producing a scope not totally to the satisfaction of connections.
The much-talked-about six-year-old has looked an exciting prospect in winning his two starts over hurdles and was one of eight of the 15 possibles representing owners Gigginstown House Stud and trainer Gordon Elliott.
"Gordon called me a short while ago and told me the horse scoped ordinary. He now won't run," said Gigginstown's racing manager Eddie O'Leary. "It's not a bad scope. Hopefully he'll run at the winter festival in Leopardstown (in February).
"We've got plenty in it (at Naas), so we'll run what we can on Sunday."
Having been installed as the odds-on favourite when the race was priced up on Tuesday, Samcro had been overtaken at the head of the ante-post market by the Willie Mullins-trained Next Destination, who was an easy winner of the Grade Two Navan Novice Hurdle last month.
