Navan's fixture on Saturday is subject to an 8am precautionary inspection on raceday morning.
Officials at the County Meath circuit must assess conditions as an overnight frost has been forecast. The going is currently heavy.
If the meeting gets the go-ahead, trainer Jessica Harrington is resigned to again running two of her smartest young jumping prospects against each other - Jenari and Oscars Well.
It was not an unqualified success when they took each other on at Punchestown three weeks ago, but lack of options mean they are both out in the Irish Stallion Farms EBF Novice Chase.
Jenari, a Grade Two novice hurdle winner last season who scored nicely on his chasing debut at Naas, at least completed the course last time, but a combination of bad luck and some poor jumping meant he finished tailed off.
Oscars Well, who was second in the Irish Champion Hurdle and had also made a pleasing start over fences, took a heavy fall at the second fence.
Robbie Power takes the ride on Oscars Well, with Mark Walsh on Jenari.
"I have to run them both, because I need to get a run into them before options at Christmas and there's just nowhere else to go," said Harrington.
"Neither had a great experience last time but they've come out of the race well and just need a bit more practice.
"The weather has been horrible over here and the ground at Navan will be heavy, but what can you do?"
