According to the EFL website, matches over the penultimate weekend of the regular season are to be announced 3 weeks in advance.
I guess it's possible they have already decided and announce ahead of time.
I may well be missing something obvious but to get promoted at Blackburn:
- we need to be 10 points ahead of 4th place downwards going in to the game and then beat Blackburn (currently 11 ahead)
- we need to be 8 ahead of Boro going in to game and win (currently 9) and 10 ahead of Ipswich...
They're supposed to be announced on a weekly basis at this point of the season. Last one was on 4th March, so could well be the next batch announced today?
