Newport Gwent Dragons admit a frozen Rodney Parade pitch means their LV= Cup match with Saracens on Friday has been postponed.
Dragons covered their pitch on Monday in a bid for the match to be played.
But "following overnight lows of minus-eight degrees centigrade" areas of the Rodney Parade pitch are still frozen.
A Welsh Rugby Union official has inspected the Rodney Parade pitch and has confirmed that the games should be rearranged.
A Dragons statement said: "The Dragons are awaiting a decision from the LV= organising committee regarding the re-scheduling of this game.
"If the game is re-scheduled, all tickets will be valid for the re-arranged fixture.
"If it is not possible to re-schedule the game all tickets will be refunded with arrangements made for season ticket holders to reflect the reduction in Dragons home matches."
