Manager Carrick was equally confused by the referee's decision to award the hosts a penalty after denying Amad's shout for a spot-kick.
He said: "(I'm) disappointed - we created enough chances and had enough opportunities in the game. A big opportunity to go 2-0 up and we get one penalty and not the other. It's exactly the same thing really - a two-handed grab. He's [referee] got one wrong so, I don't know which one but he doesn't give us the second one. I think they're both penalties and it's a massive moment in the game and it ended up chaos after that. Massive moment and I don't understand how you can give one and not the other - it's crazy.
"It's as obvious as you can get - you've already given one so to not give the other one. It's clear, if that's what he believes is a penalty to start with then the second one has to be. I don't understand how you can't give that. And then the goal and after that it was chaos. I was really pleased when we went to 10 men we saw the game out and took a point that's a real positive. In the end the way it went you can lose those games so to take a point int he end we'll take that but disappointed not to take all three."
Asked if it was harsh to send Maguire off, he added: "Maybe - it ended up chaos at that time so decisions go in different ways and he's made that decision. Ours should've been a penalty before, we would've had two penalties and then that wouldn't have happened."
