Hangeland was dismissed after 31 minutes for a two-footed challenge on Lee Cattermole with the game still goalless.
"I think he was probably the only one in the stadium who really thought it was a red card," he said.
"It would have been nice if most of the referees had played football themselves, it would be nice if sometimes they could make decisions in the spirit of the game.
"I can't remember having a red card at this club, he (Hangeland) is a nice boy and told me it was not intentional, he slipped. I won't say that it is a common thing for him because I haven't seen him do this tackle."
