Officials at Ascot have called a second inspection for 11.30am to determine whether this afternoon’s fixture can go ahead.
An initial precautionary check took place at 8am, while racing on Friday also had to pass an inspection before taking place, following persistent rain this week.
A six-race card is scheduled to start at 12.40, and features staying king Paisley Park in his defence of the Marsh Hurdle at 2.25.
Clerk of the course Chris Stickels said: “We’ve called a further inspection for 11.30am.
“It’s not so much Swinley Bottom, it’s the area going down the hill to Swinley Bottom.
“It’s marginal and we’re moving rails and hurdles to get off that piece of ground and find a racing line.
