Sheffield United's Sky Bet League 1 clash with Peterborough United has been postponed following a pitch inspection on Wednesday morning.
Referee Craig Pawson took the decision to call off the match due to standing water on the pitch at Bramall Lane.
Pawson told the Blades' official website: "There are several areas of the pitch that are causing real concern.
"The pitch is very heavy already and with the forecast for more rain we have to think about the safety of the players and officials. There is no way this game could start.
"There is standing water already and with the forecast in mind conditions are not going to improve."
