Villa's Welsh international full back was stretchered off 15 minutes from the end of the game and the American international shown a straight red card.
"I wanted to check it wasn't a broken leg after the game. The doctors have seen the lad and we don't think he's broken his leg," said the Villa boss. "It was a disgusting tackle and I was outraged by it. Chris Coleman and his team don't do those type of things.
"It was a bad tackle, Chris acknowledged that and the referee dealt with it."
