Flemenstar is reported to be in top form ahead of Saturday's Hennessy Cognac Gold Cup at Leopardstown in a field of 10 entries.
Francis Casey, son and assistant to trainer Peter, said that their stablestar had done "a terrific bit of work last week" and is on target for his second appearance over three miles.
"He has been in great form since and we'll take him over to The Old Vic on the Curragh to do another bit and that should leave him spot on for Saturday," said Casey Jnr.
Flemenstar – which holds entries in the Champion Chase, the Ryanair Chase and the Gold Cup at next month's Cheltenham Festival – weakened into third in his first attempt at three miles behind Tidal Bay in the Lexus.
The Willie Mullins-trained Sir Des Champs – a fast-finishing fourth in the Lexus – will renew rivalry while last year's Hennessy hero Quel Esprit is also a possible.
Sir Des Champs' owners, Gigginstown House Stud, also have the Tony Martin-trained Bog Warrior in the mix.
Mouse Morris is set to saddle China Rock, while Joncol, and Ted Walsh's Seabass complete the entries, although the latter has been declared to run over hurdles at Fairyhouse today which is subject to an 8am precautionary inspection this morning.
Tomorrow's meeting at Down Royal also hinges on an 8am inspection today. The track is currently raceable.
