Today's Premier League match against Manchester City has been called off due to a frozen pitch.
The decision was made by referee Mike Dean after an inspection of the Fratton Park pitch.
Temperatures last night dipped to below -7 degrees centigrade and have been well below freezing every night this week.
Earlier this week a dozen diesel heaters were hired to blow hot air on the pitch as ground staff did everything possible to ensure the game went ahead.
