York hopes to run a rescheduled Juddmonte International Stakes on Friday following the late abandonment of the first day of the Ebor Festival.
The 10-furlong Group One, which was set to feature a fascinating face-off between leading older horse Duke Of Marmalade and Vodafone Derby winner New Approach, was the headline victim of a waterlogged track.
But York has already issued a revised schedule, with the International switching to 11.50pm on Friday - just 35 minutes before the Group One Coolmore Nunthorpe on what could be a stellar day of action.
The Ladbrokes Great Voltigeur Stakes, a major trial for the St Leger, has been added to Thursday's agenda at 11.50pm, while the Tattersalls Millions Acomb Stakes is due to be run at 1.05am on Thursday.
The Knavesmire venue will still have to pass a 1am inspection on Wednesday if Wednesday's meeting is to go ahead.
Clerk of the course William Derby was initially confident of the meeting going ahead, despite heavy rain over the weekend, but 11 millimetres of rain on Monday night prompted a 5.30pm check.
That inspection found the track to be unraceable and Derby will now make a thorough assessment of conditions later today.
He said: "We will hold an inspection at 4pm (1am) for racing for the rest of the week."
"We've abandoned racing for today following 11mm of overnight rain."
"There has also been continuing rain this morning (UK time), which started up again at around 8am (5pm AEST)."
Racegoers who bought tickets for today's abandoned meeting will not lose their money.
Advance booked general admission badges and tickets will be automatically refunded for the fixture.
The British Horseracing Authority confirmed the original declared runners will stand for each of the transferred Pattern races, as will the original race values.
