Trainer Rebecca Curtis says Lisnagar Oscar won't feature in the Long Walk Hurdle after sustaining an injury at Newbury last month.
The seven-year-old came home seventh in the Grade 2 Ladbrokes Long Distance Hurdle on November 27 as Thyme Hill went on to claim victory.
Curtis was hoping to take the Stayers' Hurdle winner to Ascot on December 19 for the Grade One Long Walk Hurdle, however, she has been forced to change their plans.
“He struck into himself in the Newbury race, and also (jockey) Sean (Bowen) felt he made a bit of a noise, so we're going to get his wind touched up,” Curtis said.
“He gave himself quite a nasty overreach and was very lucky – because he just missed his tendon.
“He won't need much time off, but obviously the Long Walk would be too soon.”
With Ascot off the agenda, Curtis is now looking further ahead with the Cleeve Hurdle at Cheltenham his most likely destination.
Curtis added: “I'm just going to get him right for the Cleeve Hurdle at Cheltenham at the end of January, I think.”
