Heavy overnight snowfall has covered the Boundary Park playing surface but the club are doing everything they can to get the game on.
A statement on the club website said: "A military-style operation has this morning swung into action at Boundary Park to ensure Sunday's FA Cup fourth-round tie against Liverpool goes ahead.
"Groundstaff and an army of volunteers have begun clearing snow from the pitch, stands as well as the approaches to the ground.
"Contractors have also been brought in to clear the car parks.
"The heavy overnight snow was the club's worst nightmare with the big cup tie against Liverpool little over 24 hours away.
"Further volunteers are needed and, if you can help, simply turn up at Boundary Park, ideally with a shovel."
