Samcro will not run in Naas' only Grade One, the feature Lawlor’s Of Naas Novice Hurdle, on Sunday after an unsatisfactory scope this morning.
The hot favourite for the Neptune Novices Hurdle at the Cheltenham Festival, one of the most hyped horses in recent times, was set to take on Willie Mullins' Next Destination in one of the clashes of the season so far.
However, Gordon Elliott's unbeaten novice will not feature on the card in Kildare.
Eddie O'Leary, racing manager of brother Michael's Gigginstown House Stud, told RTÉ Sport of a possibility of running Samcro in Dublin Racing Festival at Leopardstown or even sooner at Punchestown.
O'Leary said: "He scoped this morning and we weren't totally happy with it but it's nothing at all really.
"Rather than take a chance, we will wait for Leopardstown. We'll be keeping Mengli Khan and Samcro apart.
"It's possible Samcro could even go to Punchestown on Saturday week."
That would be for the Grade Two Sky Bet Moscow Flyer Novice Hurdle.
