With the match moments from conclusion at Griffin Park and the score 3-1 to The Pilgrims, the defender was dismissed for a two-footed challenge on David Norris.
Roget, who was jeered by his own fans as he left the pitch, has admitted no guilt or wrong-doing over the incident, and has now been transfer listed.
In a double blow for the stopper, manager Wally Downes has also fined the 26-year-old two weeks' wages for his indiscipline.
The Bees' defence is already down to its bare bones, with Downes now having a selection poser of who will partner Ibrahima Sonko in their backline against Rushden & Diamonds.
