Rhys Browne will miss Town’s final Checkatrade Trophy group match against Plymouth Argyle on Tuesday.
The winger has received a booking in each of the Glovers’ games in the competition so far, resulting in a one-game suspension.
Darren Way’s side can progress to the second round in first place or runner-up in Group D.
Top spot would confirm a home tie with AFC Wimbledon while second position would mean a trip to MK Dons.
