Cardiff City manager Mark Hudson told BBC Radio Wales:
"I feel sorry for the players and the fans because the turning point was the penalty and sending-off which is very difficult to take.
"He [Jack Simpson] was the right side of the player and the forward has kicked the back of his leg. I was surprised it was also a red card and we will have to look to see if we can do anything [appeal] about it. It was very disappointing.
"However we didn't start well and you can't do that. We kept in the game by grinding away against a team in form but then a decision goes like that."
