The first race tomorrow is the 13:30 at Punchestown.
Exeter's clerk of the course Daniel Cooper says the track is facing a "significant uphill battle" ahead of an 08.30 inspection to assess the conditions for Sunday's scheduled meeting. Elements of ground have been frozen solid for the best part of a week with temperatures dipping below freezing for five nights in a row.
Exeter has cancelled its three chase races due to frost but will go ahead with a card consisting four races over hurdles and a bumper after a second Sunday morning inspection.
It means that the 14:40, 15:40 & 16:40 have been abandoned.
