Sedgefield's meeting scheduled for Friday has been abandoned following an inspection.
The card had already been revised earlier in the week with the chase course deemed unraceable.

Ten millimetres of snow and rain fell this morning, with snow lying on the track and temperatures due to fall to minus 4C overnight.
