Sunday's British U21 Semi-Final has been postponed due to the weather.
The decision to postpone the meeting was taken this afternoon with rider safety playing a major factor.
Team boss George English said: "The track is already waterlogged from the rainstorms and downpours we've had this week.
"The track team can't get access to begin the clean-up operation until Sunday morning, and even if the weather held out enough to dry the track itself, the surface hasn't been raced on since last October so would require extensive repair work on top of everything else.
"Bearing in mind the line-up for tomorrow's match features some lesser-experienced riders, we've obviously had to take into account their safety which is paramount."
No re-staging date has yet been decided.
