The Carling Cup semi-final, second leg, between Middlesbrough and Arsenal has been postponed because of bad weather.
The pitch is playable, but approaches to the stadium are in a dangerous condition because of ice and snow.
The decision to call the match off was made following discussions between referee Dermot Gallaghar, the police, the local authority and the stadium safety committee.
The match will now be played on 3 February, kick-off at 2000 GMT.
"We're naturally very disappointed that such a big game has been postponed," said a Middlesbrough spokesman.
"But we agree that public safety has to take priority.
"Although the pitch was in perfect condition it was felt that the condition of the stadium approaches and surrounding area meant that public safety could not be guaranteed."
The postponement brings mixed news for Boro boss Steve McLaren, whose side take a 1-0 lead into the second leg.
The delay means that injured defensive duo, Gareth Southgate and Ugo Ehiogu, have more time to recover from their respective hamstring and groin injuries.
But it also means that Middlesbrough's Premiership tie with Birmingham - which was to be played on 3 February after already being postponed because of a waterlogged pitch at St Andrew's- will have to be rescheduled again.
