Hendon revealed after the game that he has called his beleaguered charges in for extra training on Sunday.
"We got off the bus and simply didn't perform," he said.
"When we conceded early on we knew it would be difficult to get back in the game. There will be questions asked.
"To say I am disappointed is an understatement. We need to sort out what has gone on as soon as possible because we have another difficult game on Tuesday."
