Heavy rain this week has placed several meetings in doubt with Newton Abbot on Friday the latest card to be abandoned due to the rainfall.
Haydock's Thursday evening card was abandoned because of waterlogging after an early-morning inspection.
A further 10mm of overnight rain left conditions unraceable at the Merseyside track, which had already been badly hit by the downpours of the past week.
Both Nottingham and Yarmouth, also subject to inspections, were both passed fit to race.
Uttoxeter became the second card lost to waterlogging, however, on Thursday.
The Staffordshire course reported more than 100mm of rainfall in the past six days, including 30 in the previous 24 hours, confirming the abandonment shortly before 7.30am.
Friday's card at Newton Abbot was also lost to the weather, with the track reported to be waterlogged.
Leicester's meeting on Saturday evening needs to survive a 2pm inspection on Friday.
The course tweeted that as much rain has fallen in the past four days as in the whole of 2018.
