Frost threatens Navan Saturday's meeting at Navan is in doubt due to the threat of severe frost, forcing officials to announce a 7.30am inspection. Although the track is currently described as heavy but raceable, temperatures are forecast to get as low as minus six overnight and there is also the possibility of freezing fog. Turf Club press officer Cliff Noone said: "Things are fine at the moment but if the temperature does get as low as forecast, obviously they are going to be in trouble. "They are going to have a look at 7.30am and make a decision after that."
