Sublimity has been ruled out of the Champion Hurdle due to a leg injury.
The 10-year-old had been a general 20-1 shot for the March 16 contest , and appeared to be back in form this season after being placed in three Grade 1s.
But trainer Robbie Hennessy revealed that he had suffered a late set back and would not be sdeen in action again this season.
He said: "He's got a suspensory injury. It's just a knock and it's hard to really know how he did it - it could have been rolling around in his box, getting cast or in a routine gallop.
"He's lame and the vets have told us he needs three months' rest, so he won't be back this season.
"We're all gutted here. It's a shame as he had a really good gallop at Leopardstown last week. He's been in good form and running well all year and the ground is just starting to coming right for us.
"It's just one of those things. He could be sound again in two weeks' time, but he just needs the time off as he could end up lame again."
