The Pirates saw three players limp off in the recent draw with Charlton and then had David McCracken sent off in the defeat at Bournemouth on Easter Monday.
Midfielder Jeff Hughes (wrist) could miss the remainder of the season, while defenders James Tunnicliffe (ankle) and Danny Coles (Achilles) missed the trip to Dean Court and are likely to be sidelined again.
Defender McCracken was dismissed for an elbow on Cherries defender Adam Smith and will miss the rest of the campaign.
In a bid to boost the squad, caretaker manager Stuart Campbell has recalled versatile midfielder Charlie Clough from his loan spell at Bath.
The 20-year-old featured 11 times for the Blue Square Bet Premier club, scoring twice.
