Crewe are sweating on the fitness of Ashley Westwood ahead of the crunch fixture.
Westwood suffered severe bruising to his foot during last weekend's 1-1 draw at Torquay and is currently rated as 50/50.
If Westwood fails to recover, Lee Bell is ready to step in having impressed when he replaced his team-mate at Plainmoor.
Captain David Artell is hoping to recover from a hamstring injury, but fellow defender Carl Martin is ruled out with a similar complaint.
Dan Shelley is back in training following a calf problem and provides an extra option for boss Steve Davis in midfield.
A point against the Shots will be enough for Alex to secure their place in the League Two play-off places.
Meanwhile, Jordan Roberts will be suspended for Aldershot.
The youngster was sent off in the closing stages of last weekend's 2-2 draw against Rotherham and now serves a one-match suspension.
On-loan defender Troy Brown is back in contention for the clash at Gresty Road having been unable to face his parent club last Saturday.
Brown's absence forced one change against the Millers, with midfielder Josh Payne restored to manager Dean Holdsworth's reshuffled XI after a hamstring injury.
Holdsworth is not expected to have any new injury problems for the clash, leaving just long-term absentees Ross Worner (back), Alex Rodman (pulmonary embolism) and Michael Rankine (leg) in the treatment room.
