Cause Of Causes leads the Irish challenge among 33 confirmations for Saturday's Betfair Hurdle at Newbury.
After winning The Ladbroke at Ascot before Christmas, he is on course to tackle another big handicap engagement.
Trainer Gordon Elliott said: "He's fine and the plan is for him to go to Newbury.
"We've also confirmed him for the Deloitte in Leopardstown, but that is just in case something happens with the weather or something like that.
"We're looking forward to running him."
Elliott also has Discoteca in the field with both Willie Mullins and Tony Martin also double-handed with Midnight Game and Quiscover Fontaine, and Edeymi and Thomas Edison respectively.
The Eddie Harty-trained Princeton Plains rounds out a strong Irish contingent.
Other notable contenders include Court Minstrel, Cotton Mill and Claret Cloak but Mullins' Abbey Lane does not feature.
