Hendon manager Gary McCann spoke after the Lowestoft game about both red cards and the overall performance.
"I was disappointed and frustrated with Kevin's reaction. I thought I had got through to him. However, I have no doubt he is singled out because his reputation precedes him.
"Kevin has come on so much this season with his discipline - yes, he has had a lot of bookings, but they have been because of his effort and trying too hard.
"I was also disappointed with his reaction to his red card, but he did apologise on Twitter afterwards. I had a heart-to-heart conversation with him on the way back home.
"As for Fisher's red card, it was a little unfortunate. On a booking already, maybe he shouldn't have gone for the ball.
"After that it was a real backs against the wall response and the players were magnificent. We only had two substitutes that we could call on, and every player gave me everything they had. Berkley kept us in the game, and it was most unfortunate his slip led to the only goal.
"It has been a long season and in the past week we have been running on empty. We have had a small squad and our finishing schedule was asking too much of us. But I must thank all of my backroom staff who have worked heroically throughout the season."
