Carlisle United have insisted they are ‘very, very confident’ Saturday’s visit of Pompey will take place.
The Brunton Park pitch has been left under water following the heavy flooding which has swept the north of England.
According to the club, by this morning half the pitch was under 12-14 inches of water.
Even before they face Paul Cook’s men, the Cumbrians are scheduled to host Doncaster in an FA Youth Cup fixture tomorrow night.
Currently, four high-capacity pumps are in the process of clearing water from the pitch.
Carlisle have not had a match called off for rain for more than 10 years.
And Andy Hall, the club’s media officer, believes the Pompey fixture has every chance of going ahead as planned.
He told The News: ‘According to the Met Office, by last night it was about 241mm of rain to fall in 48 hours.
‘That is half the monthly predicted rainfall arriving within only two days.
‘At present there are four high-capacity pumps working away. These will finish at the end of tonight or tomorrow.
‘The pitch actually dries fairly quickly so the key will be the weather from now.
‘Currently the flooding is 12-14 inches deep stretching up to the half-way line. That is a significant chunk of water.
‘But we have been in this position before. One match we had three inches of water on the pitch with nine hours to go before kick off, but still managed to play.
‘Right now we are very, very confident the Portsmouth match will go ahead as planned.’
Back in January 2005, Carlisle were devastated by floods, with Brunton Park also heavy affected.
The rivers Peterill and Eden both meet behind the northern end of the ground, ensuring flooding remains a constant concern.
However, since improvements 10 years ago, the Cumbrians’ home fixtures have avoided falling foul of such weather.
Hall added: ‘After January 2005 the Environment Agency put in flood defences around the ground following massive flooding.
‘Since then we’ve not had a single game called off due to rain water.
‘So we are extremely confident that will not change come Saturday.’
Carlisle are presently in 10th spot, three points behind Paul Cook’s troops.
They lost 2-0 at Bristol Rovers at the weekend.
