Musselburgh is to stage an extra meeting on Monday.
The British Horseracing Authority announced the fixture as a result of recent abandonments at Ayr and Hamilton.
A six-race card has been scheduled, which could become seven if a division is needed, and will be run as a twilight fixture.
Over £55,000 in prize money will be on offer, with the Listed Arran Stakes, originally scheduled for the Friday of the Ayr Gold Cup meeting, the feature.
