Birchall has been recovering from an ankle injury that now looks to have cleared up, whilst Rhys Day is also on the road to recovery, although is unlikely to feature against Boston.
He is due to take part in a training match this week so boss Peter Shirtliff can access his progress.
On the subject of long term injury Chris Beardsley, Shirtliff told the official Mansfield Town website "I don't think Chris will play any part for the remainder of this season but hopefully the news from the surgeon he is visiting will be promising and he can return to training in readiness for the pre-season schedule."
Boston manager Steve Evans meanwhile made the most of his free weekend, by taking in the Stags local derby at Meadow Lane.
