The Iron play their penultimate away game of the season on Tuesday night, when they make the trip to take on Newport County (6.30pm kick-off).
United enter the match at Rodney Parade looking to arrest a run of four straight defeats and to get a victory which would mathematically clinch League Two survival with two games still to go.
A win would also see the Iron climb above 21st-placed Colchester and into 20th position.
Jordan Clarke looks set to miss the rest of the season with a knee injury picked up at Forest Green last weekend, which forced him to withdraw after 20 minutes.
Harrison McGahey returned to the starting XI at Forest Green and missed out at Mansfield and against Walsall through a quad issue, which will continue to be assessed.
Jai Rowe picked up an eye injury at the weekend, which will be assessed again on Tuesday morning.
Left-back Junior Brown is out with a hamstring injury that forced him off against Bradford City and attacker Jordan Hallam is out with the hamstring problem which he suffered against Oldham Athletic in March. Elsewhere, Olufela Olomola's season looks to be over after he suffered a medial ligament injury.
Striker Aaron Jarvis (hamstring) is set to miss the rest of the season, while midfielder George Hornshaw and goalkeeper Adam Kelsey are both expected to be out for the remainder of the campaign too following ankle surgery.
Newport County sit seventh in the table and, with teams breathing down their necks, need a victory in their game in hand to bolster their League Two play-off hopes. They could climb a place with victory.
Michael Flynn's side drew 0-0 at fellow promotion hopefuls Exeter City on Saturday and were 2-0 victors over Crawley Town at home last weekend.
Tristan Abrahams and Padraig Amond are joint top scorers with eight goals apiece, while Scott Twine has scored seven goals and set up a further seven.
Defender Mickey Demetriou tops the appearance tables with 42 to his name, while Josh Sheehan follows on 40.
The two sides drew 1-1 at the Sands Venue Stadium on the opening day of the League Two season, with Ryan Loft scoring a spectacular second-half goal.
The Iron were defeated 2-1 in both games last season.
