Aldershot manager Kevin Dillon is waiting on the fitness of defender Adam Hinshelwood ahead of the visit of Northampton.
Hinshelwood missed the 0-0 draw with Notts County at the weekend after succumbing to a calf niggle but could be fit to face the Cobblers.
However he may struggle to regain his place after Chris Blackburn deputised successfully at Meadow Lane as the Shots recorded a fourth straight clean sheet.
Dillon said: "Hopefully Adam will be ready for Tuesday but he knows that other players are in possession of the shirts and he'll need to shift them."
Left-back Dean Howell remains a long-term absentee as he recovers from a hip operation as Dillon looks for his first win in management.
Northampton forward Adebayo Akinfenwa looks set to miss out as the Cobblers travel to Aldershot for the first time in 19 years.
Akinfenwa scored two second-half goals on Saturday as Ian Sampson's men came from behind to draw 2-2 with Crewe but is struggling for fitness and is unlikely to feature.
On-loan Middlesbrough defender John Johnson - who scored an own-goal on the weekend - is also out after he picked up a hamstring injury late on but Peter Gilbert is back from suspension.
Striker Courtney Herbert and midfielder Abdul Osman remain sidelined by their back injuries, while Dean Beckwith is out after injuring both hamstrings at MK Dons earlier this month.
Winger Liam Davis is set for a scan on his injured foot and misses out as the Cobblers look for a first league win in November.
