Defensive trio Michael Townsend, Shane Duff and Josh Low are all doubts for Cheltenham`s home clash against Aldershot, as is midfielder David Bird.
Townsend (ankle) missed the goalless encounters at Shrewsbury and Rotherham along with Tuesday`s entertaining 3-3 draw at home to Darlington and his participation is again in doubt.
Fellow centre-back Duff was replaced after just 27 minutes of the midweek clash against the Quakers nursing a calf problem which is not thought to be a long-term problem but is threatening his involvement for Saturday.
Low meanwhile took a whack to his leg in the same game and was also forced off, with all three set for late fitness tests and manager Mark Yates facing a potential dilemma at the back.
To make matters worse for the Robins boss, on-loan left-back Danny Andrew has been recalled by parent club Peterborough and will not be available.
Bird missed out altogether on Tuesday due to the heavy knock he took to his calf at the Don Valley Stadium last weekend and he is rated as 50/50.
Aldershot's play-off hopes could be boosted by the return of Andy Sandell and John Halls.
Left-back Sandell has been out since injuring his hamstring at the beginning of March while Halls has missed most of the season with a series of groin injuries.
However, the duo are close to fitness and could be included as Kevin Dillon's men look top keep their place in the top seven.
Right-back Ben Herd continues to miss out with the ankle injury he sustained against Port vale a fortnight ago so Chris Blackburn will fill in at full-back.
Marlon Jackson is now fully fit after a hamstring injury and will partner top scorer Marvin Morgan in attack.
