Snow has forced the cancellation of this weekend's race meeting at Doncaster Racecourse.
Saturday's meeting at Town Moor has been abandoned with the course under several inches of snow.
A spokesman said: "The course remains snow covered and the forecast gives no prospect of conditions allowing a thaw."
Meanwhile, Doncaster Rovers has announced the closure of its club shop, ticket office and academy from 1pm due to the weather conditions.
A spokesman said fans wanting to buy tickets would still be able to do so online or by calling 01302 762576 (after 1.30pm).
Rovers are due to take on Bury in a 3pm kick-off at the Keepmoat Stadium on Saturday.
A decision has yet to be taken on whether the game will go ahead.
