FC Halifax Town face the first of two potentially season-defining games in four days when they travel to Barnet on Saturday (3pm kick-off).
Halifax also face Grimsby on Tuesday knowing their fate is in their own hands after midweek results went in their favour.
Barnet and Grimsby both dropped points against Southport and Woking respectively, while Alfreton and Braintree both lost at home to Aldershot and Macclesfield respectively and failed to overtake the Shaymen.
Town are now fifth in the Skrill Premier after a run of seven games unbeaten and having won seven of their last nine matches.
Neil Aspin’s side have also kept six clean sheets in their last seven games and have not conceded a goal in eight hours of football since Alex Brown’s goal for Hyde in their 5-1 defeat more than a month ago.
Adam Smith (pictured) is likely to return to the starting line-up on Saturday after missing last week’s 1-0 win at Nuneaton with a groin injury.
Paul Marshall has also shaken off his illness from that game and should retain his place in the side.
Marc Roberts faces a late fitness test after missing the Nuneaton win with a hamstring injury, while Simon Ainge serves the second of his two-game suspension, so at least one of last Saturday’s defensive duo, Danny Lowe and Chris Smith, looks set to keep their place in defence.
Lee Gregory will equal his worst run of the season if he fails to score on Saturday after failing to find the net in his last two outings, although Town have scored in each of their last six away games.
Barnet have only won two of their last eight games and drew 1-1 at Southport on Tuesday.
England C striker Jake Hyde is their top-scorer with 11 goals, but has only netted two in his last nine games.
Manager Martin Allen is in his fourth spell in charge at Barnet, having taken over on March 19 and is yet to lose since returning to the club.
Goals from Scott McManus and Lois Maynard sealed a hugely-impressive 2-1 win for Town in the reverse fixture back in September.
Town’s last visit to Barnet ended in a 3-1 defeat in 2005, with Lewis Killeen giving Halifax the lead before substitute John Grant was sent-off in the second-half.
