The French striker was dismissed by referee Graham Barber for unsportsmanlike conduct after 72 minutes of the 4-0 home drubbing having already been booked 10 minutes earlier, his fifth booking of the season.
The yellow card alone would have seen Dugarry miss one game as that took his tally to five yellows for the season but the red card will warrant another automatic one game ban.
If my maths is right that means that Dugarry will now have to sit out the games against Middlesbrough at home on 20th December and Manchester City at home on Boxing Day.
