Heavy rain has put paid to today's English meeting at Nottingham.
The Flat fixture was abandoned after an early-morning inspection found waterlogged patches in the straight.
"We had a further 8mm of rain overnight, which makes nearly an inch and a half since Sunday morning," said clerk of the course Charlie Moore.
"There are too many areas of standing water in the straight and it would not be safe."
Racing at Exeter has also been called off today, leaving Newcastle as the only surviving meeting.
