Edgar Davids and Carl Fletcher were both sent off for Barnet who suffered a 2-1 defeat to Salisbury City.
Salisbury opened the scoring with 17 minutes played but the Bees hit back just two minutes later when Jake Hyde flicked the ball home.
The Bees were by far the better side after levelling but with just under 20 minutes remaining Fletcher received a straight red card and conceded a penalty which Jamie White dispatched.
