I remember home games v Southampton and Charlton being postponed less than a couple of hours before kick off.
Regarding the crowd for Sunday I can't see Middlesbrough bringing more than 2,000 which is quite frankly pathetic, so there's 1,000 taken off capacity and then there's the old family enclosure which used to be at the back of Leazes Level 4 which they changed to a corporate area and haven't sold any tickets in there this season, Sundays game included, which leaves another 1,500 empty seats so that brings the crowd down to below 50,000 straight away.
