However, there are still eight league games, most of which have significance at either end of the table.
But which games should you be keeping your eye on this Saturday? We've picked three that catch the eye.
Darlington v Kidderminster Harriers
After three successive defeats at the turn of the year, Darlington went on a good run which saw wins over fellow strugglers Leamington, north-east rivals Blyth Spartans and Bradford Park Avenue as well as draws against Alfreton Town and Chorley.
But a disappointing 3-0 loss at St James Park against promotion-chasing Brackley Town last weekend has left Tommy Wright's side still only five points above the drop zone, making Saturday's Blackwell Meadows game against play-off chasers Kidderminster Harriers a vital one.
Last Saturday's 2-0 Aggborough defeat to current leaders Harrogate Town brought an end a terrific run for Harriers, who hadn't lost in the league since September 12th. Currently fifth, they have a five-point cushion on the chasing pack and John Eustace's side will be keen for another three points from their journey north.
It was a thrilling 3-3 draw when the sides met on November 11th at Kidderminster.
Leamington v Blyth Spartans
Blyth head down to Warwickshire holding a healthy eight-point advantage over eighth-placed Bradford Park Avenue in the race for a play-off spot.
But Alun Armstrong's side know they can't relax as a couple of indifferent results could mean a nervy end to the season. And their final ten games after Saturday's visit to The Phillips 66 Community Stadium include matches against fellow high-flyers Salford City, Harrogate Town and Kidderminster.
The Brakes, meanwhile, need the points for completely different reasons, as they sit just a place and four points ahead of the relegation places. They go into the game in confident mood, however, having beaten a previously in-form Boston United side at the Jakemans Stadium.
They were beaten by the only goal of the game at Blyth on November 11th so will be desperate to avoid the north-east side doing the double over them.
Salford City v Tamworth
Salford will be hoping to take advantage of current leaders Harrogate Town being without a game to re-take top spot come 4.50pm on Saturday.
The Ammies were overtaken on Tuesday night when they could only manage a 2-2 draw at the Peninsula Stadium against Bradford Park Avenue, while Harrogate edged out Alfreton Town by the odd goal in seven. It's been a mixed start to 2018 for Salford, having won four, drawn three and lost two of their nine games to date.
However, it's been even worse for Tamworth, who have won just once since the turn of the year – form which led to the departure of manager Andy Morrell. Mike Fowler and Scott Rickards take their Lambs north to face a Salford side who they beat twice last season but lost 2-1 at home on November 11th. The caretakers will be hoping for better form than last weekend when they were held to a 2-2 draw by struggling Midlands rivals AFC Telford United.
And they will need a change in fortune fairly quickly as Tamworth have gone from being on the cusp of a top seven spot to being just six points above the drop zone.
