Racing action in the straight at Navan© Photo Healy Racing
There will be a precautionary inspection at 8am to determine whether tomorrow's meeting at Navan can go ahead.
Officials have decided to take a look in the morning due to an adverse weather forecast.
The track is currently raceable and the going is described as heavy, with the first on a six-race hurdle and bumper card due to get underway at 12.15pm.
The chase course was found to be unraceable earlier this week and, as a result, the 2m6f handicap hurdle is divided to form the six-race card.
