Rince Ri, the intended topweight for Monday's Powers Gold Label Irish Grand National, will miss the race in favour of a tilt at Punchestown's Heineken Gold Cup.
Trainer Ted Walsh made his decision yesterday and will instead rely on the novice Commanche Court.
Bobbyjo is next in line for topweight, but a decision on whether the 1998 winner takes his chance won't be made until his trainer, Tommy Carberry, walks the course this morning.
'Declarations are made tomorrow for the National so I'll have a walk around the track in the morning. It's drying out very well. It's a good drying day today so if the rain stays away it should be decent ground,' he said yesterday.
The next candidate for top weight is the English-trained Red Marauder, but he is more likely to run at Wetherby on the same day. Richard Guest, assistant to his trainer Norman Mason, said: 'It depends on the ground but we would need more rain to go to Fairyhouse. A final decision will be made on Sunday.'
Ground conditions remain good to yielding after the track avoided the heavy rain that affected much of the country on Wednesday night. 'There are heavy showers forecast over the next few days and I think the going will be on the soft side of good on Monday,' said racecourse manager Dick Shiel yesterday.
Jocks Cross has been confirmed on course for the race by trainer Venetia Williams. Riding arrangements have yet to be finalised for the nine-year-old.
