The Clydesdale Bank Premier League matches scheduled for Sunday have fallen foul of the severe weather conditions in Scotland.
League leaders Rangers were due to travel to Tannadice to face Dundee United in the noon kick-off, but the match was called off shortly after an 8am pitch inspection.
"Today's match has been called off due to the severe weather conditions overnight and this morning," a statement on Dundee United's website read.
Meanwhile, the match between Motherwell and Hearts at Fir Park has also been called off due to the freezing weather.
