Arbroath striker Steven Doris is struggling with a hamstring injury and will need to pass a late fitness test before taking the field against Stenhousemuir.
Back-up goalkeeper Tony Bullock is also a doubt with a back problem.
Player-manager Paul Sheerin said: ``This is the first of two massive games for us as if we win this one and then against Forfar next week we have taken two massive steps towards a play-off place.
``Our games with Stenhousemuir usually produce goals and if we can get one more than them we open a gap that will be difficult to close with just six games to go.''
Stenhousemuir have signed goalkeeper Chris Smith on loan from St Mirren ahead of the trip.
However, they will be missing centre-back Scott Buist through suspension as they head to Gayfield aiming for the win that will lift them over their hosts in the race for a play-off place.
The Warriors will also be without Iain Thompson and Kevin McKinlay due to calf injuries while Craig Anderson is ill.
Manager Martyn Corrigan said: ``Our last visit to Arbroath sums up our season in that we left with a point from a game that we should have won.
``Twelve draws this season has impacted on our promotion push as we should have taken full points from the majority of those games.
``However, we are looking like a side that will score goals now and that could help us win at Gayfield.''
