From my reading the leagues will stand as is, might be a case of giving every team a few points for each outstanding game to compensate teams that have a game in hand.
As far as i am aware they will then carry out promotion/relegation as normal. Not sure how this will work a bit higher up were they have play offs ? Might even come down to coin toss but we need to know that before we know if its 2 or just 1 team relegated per division. From Y2 point of view I don't think many would argue against Hegians and Rish deserving to go up, but Barnsley and WPL might feel they still had an outside chance of getting 4 or 5 wins from there last few games to give them an outside chance of staying up.
