Limestone Lad will not defend his Ballymore Properties Champion Stayers' Hurdle crown at the Punchestown Festival on Thursday.
Connections of the popular Irish 11-year-old have opted to call it a day for the season following his brave third to Baracouda and Iris's Gift in the Cheltenham equivalent last month.
Michael Bowe, assistant trainer to his father James, said: "We worked Limestone Lad on grass recently and he wasn't really letting himself down on the ground.
"Call it instinct, but I just wasn't that happy with him. Although he is physically fine, he just seems a bit off-colour.
"It would have been nice to go back to Punchestown and try to win the race for the second year running, but he's going to have a long break now and we'll give him the same sort of campaign next season."
