Worcester's match against London Irish at Sixways on Saturday has been postponed because of a frozen pitch.
Strong winds have got underneath the covers and caused some areas to freeze, making the pitch unsafe.
Premier Rugby's Phil Winstanley said: "The wind chill has frozen areas at the very extremities of the covers and made those areas unsafe for players."
It is the fifth Premiership match to be called off this weekend, with only Leicester v Wasps currently remaining.
"Player welfare has to be our prime concern and with no improvement in the forecast and therefore the conditions, we were left with no option," added Winstanley.
"I would like to thank everyone at the club for their Herculean effort.
These exceptional circumstances, the worst for well over a decade, have beaten us this time

"They have invested a huge amount of time and resource and I can't see how they could have done any more, but these exceptional circumstances, the worst for well over a decade, have beaten us this time."
Warriors general manager Charlie Little told BBC Hereford and Worcester:
"We're obviously very disappointed for all concerned that the game will now not take place.
"A huge amount of time and effort has gone in to trying to get this game ready.
"At the end of the day we have fallen just short of what would have been a fantastic achievement.
"Chris White, the match day referee, was full of praise for the obvious efforts that had gone in and was genuinely disappointed to have to call the game off.
"With a minus five wind chill forecast for tomorrow there was every chance that the pitch would begin to freeze before the match actually started."
Tickets bought in advance will remain valid for the rearranged date, which will be announced in due course.
