FC Halifax Town travel to second-placed Forest Green on Saturday (3pm) knowing a draw or a win could lift them out of the relegation zone.
Halifax drew 0-0 with Eastleigh at the Shay on Tuesday to leave them in the last relegation place but with a worse goal difference than Boreham Wood, who are one place above them and face fellow-strugglers Guiseley on Saturday in a crunch clash.
Depending on that result, a draw or a win could lift The Shaymen out of the bottom four.
Town have gone four games without a goal, their worst run since March 2008, and have scored in only one of their last six games.
Forest Green are guaranteed to finish in the play-offs, and will secure second place in the league with a point on Saturday.
But they are without a win in their last six games, their worst run of form for three years, and have won only once in their previous nine games.
They have not won at home since February 20 and have only scored once in their last four home outings.
Only champions Cheltenham have won more home matches than Rovers, who have only conceded 16 goals in 22 games at The New Lawn.
Jim Harvey was manager of Rovers between 2006 and 2009, leading them to safety after inheriting a team bottom of the table with two points from their first six games.
He then achieved an eighth place finish in the Conference in his first full season as well as a third round FA Cup tie at home to Derby and an appearance in the final of the now-defunct Conference League Cup.
