Greenock Morton say their Scottish Cup second round tie with fellow Championship side Dunfermline Athletic is "highly unlikely" to go ahead due to a frozen pitch.
The pair are scheduled to meet at Cappielow on Saturday, with a pitch inspection planned for Friday.
If postponed, the game will be moved to Tuesday 12 January at 19:45 GMT.
That would mean Morton's league game with Arbroath and Dunfermline's match against Hearts would be rearranged.
Meanwhile, Morton confirmed a further three first-team players have tested positive for Covid-19.
The club returned one positive test on 2 January, with a further two forced to isolate after being deemed as close contacts.
Morton say all players will have returned from isolation by 11 January.
