FC Halifax Town and Dartford meet for the fourth and final time this season on Saturday (3pm kick-off) in a game that could have huge ramifications at both ends of the Conference table.
Halifax can close the gap on fifth-placed Forest Green with a win and if other results go their way, while Dartford will be aiming to cut the six-point cushion that lies between them and Alfreton, who are just above the relegation zone.
There has been plenty of drama already between the two sides this campaign, with Town winning the return league fixture 2-1 despite the sendings-off of James Bolton and Lois Maynard.
In the FA Trophy, Town let a 2-0 lead slip in the first game before beating The Darts 3-1 in the replay at Droylsden.
Town have drawn a blank in their last two outings against Kidderminster and Southport, the first time they have failed to score in back-to-back league games since January last year.
Dartford have won just once in their last eight games and have gone 30 league games without keeping a clean sheet against Torquay in August, their only shut-out of the campaign.
The Darts have conceded more penalties, 10, than any other Conference side and have had the fewest attempts at goal in the entire division.
Defender Steve Williams was expected to train on Thursday night and could be in contention to return to the squad for Tuesday’s game at Aldershot after a hamstring injury.
Midfielder David Mellor has been recalled by parent club Oldham from his loan spell at The Shay after making just one appearance for Halifax.
