I'd love the rule to be that the game restarts at the point it was abandoned but there are practical difficulties.
What if a player who was playing in the original game is injured or, if played after the January window (e.g. if the original game being played was in December), who replaces that player.
Or a player is now suspended. Does he play in the replayed game restart and serve his suspension in another game? Or is he suspended from the replayed game and therefore his suspension only lasts 11 mins plus stoppage time?
Reality is, much as we might not like it in this instance, the likely outcome of the game being replayed is not unreasonable.
Interestingly there has been a precedent this year of the losing team (Wealdstone?) agreeing that the result should stand but this was when they were deep into stoppage time and a couple of goals down. The match was abandoned due to a serious injury IIRC.
No way Ipswich would agree at one down with 10+ mins to go! And we wouldn't either!!
