Officials at Leicester have called a further inspection at midday ahead of this afternoon's meeting.
An initial check just before 8am proved inconclusive with temperatures having dropped to -2C overnight.
It is expected to warm up as the day goes on, but another inspection has been deemed necessary.
That 10.30am check proved inconclusive, with a third inspection now called for noon.
