Eastbourne Borough boss Garry Wilson could not defend Darren Baker after the defender was sent off in their defeat at leaders Weymouth.
Baker was shown two yellow cards within seconds of each other after kicking the ball away then sarcastically applauding the referee on 71 minutes.
Wilson said: "It was poor discipline from Darren and he deserved to be sent off. He will learn from this but the higher you get in the leagues, the more you have to control yourself."
Wilson's men defended gallantly in the first half to keep Weymouth, who are managed by Steve Claridge, at bay.
Borough went closest through a John Westcott header.
However, it was Claridge who got the winner in 59th minute when he followed up Lee Phillips' parried shot.
