The game was called off Friday following an inspection of the playing surface at Bloomfield Road by match referee Peter Walton.
Blackpool says Walton "expressed concern that the severely affected areas of the playing surface would not thaw sufficiently for the game to be completed." Bloomfield Road doesn't have under-soil heating and stadium staff had been using hot-air blowers to try to thaw the pitch.
United moved to the top of the league last weekend but former leader Chelsea and Arsenal can overtake with wins on Saturday.
Chelsea hosts Everton and Arsenal is at home to Fulham.
