Got my tickets for the Upper Tier this morning but the seats are numbered 5 and 6 so it looks like the Upper Tier will be sold out today.
since my first competitive Sheffield derby match in October 1970, I have missed only two competitive Sheffield derby matches (both in 1980 as I was playing football in Kortrijk when we drew 1-1 at BDTBL and I was playing cricket when we lost 2-0 at the sty in the League Cup 1st round, 1st leg)
Got mine on Monday and seat numbers were 7 and 8 row 6 and a friend who bought one about 5 mins after me had row 25 seats. Different people in the ticket office have sell different batches. They also said that they weren't selling the lower tier until the uppper was sold out which may give succour to some of the Thurs/Fri worriers.
