Snow puts paid to afternoon fixture.
Sunderland's Barclays U21 Premier League game against Middlesbrough, scheduled for today, has been postponed.
The fixture was due to take place this afternoon but has been called off due to the recent poor weather conditions affecting Boro's Rockliffe training base.
No new date has yet been set.
The postponement means Kevin Ball's side are still waiting to play their first game of 2013 - they will now host Fulham on January 28.
