With East Retford conceding the game on Friday, Boston Rugby Club secured a home walkover victory and importantly five league points to retain their eighth place in the Midlands 3 East (North).
Boston entertain Nottingham Casuals on Saturday, who won the earlier encounter 29-5.
Casuals lie in third place and will prove a stern test for Ashley Coates' side.
All support welcomed.
The game is preceded by a Vice Presidents' and sponsors' dinner.
