FC Halifax Town face a nervy 180 minutes before the season’s end, with a number of permutations still possible in deciding their fate.
Boreham Wood, in 20th, and 19th-placed Guiseley, play each other on Saturday, meaning that whatever happens, Town will not be relegated to the Conference North this weekend.
If Halifax win at Forest Green tomorrow, they are guaranteed to climb out of the bottom four.
They will also be guaranteed survival if they win both their remaining matches, with Macclesfield visiting The Shay on the final day of the campaign.
If Boreham Wood or Guiseley win tomorrow and Halifax lose, The Shaymen will be unable to catch them.
Should Town and Boreham Wood both either lose or draw and Altrincham win against Welling, then The Robins will be in with a shout of staying up going into their last match at Braintree.
Torquay, who play Barrow on Saturday, are not safe mathematically, but would appear unlikely to be in danger, with just one point required from their last two games to ensure their survival.
Guiseley face Torquay at home on the final day, with Boreham Wood travelling to Welling.
Chester, who are in 18th place, are four points clear of the drop zone and could still be dragged into the drop zone, unless they win one of their last two games against high-flying Grimsby and Gateshead.
