Hamilton inspect on Sunday
Hamilton's fixture on Monday is subject to an 11.30am precautionary inspection on Sunday.
Although the track is raceable, course officials are taking no chances in light of a mixed forecast.
The going is currently heavy at the Scottish circuit.
Clerk of the course Hazel Peplinski said: "It's not been a good spell. "We raced on Sunday and Monday on heavy ground, which opened the ground right up, and we've had very few dry days since.
"The forecast for Sunday is a big worry, which is why we are taking a look when we are."
