"I'm very pleased. We got the luck which the FA Cup has the habit of throwing up," said Curle.
"The sending off completely changed the game. Our plan was to put the ball into good areas and I must pay tribute to our midfield three. We hounded them, got about them and used the ball very well.
"There was a lot of negativity before the game because of players going down with injury, but I thought we came together as a club. We all gave it a massive effort."
