Gutierrez did not want to address the referee's decision to dismiss the Ivory Coast international on 25 minutes.
The ex-Real Mallorca winger told the Evening Chronicle: "I did not see the tackle, but I never want to speak about the referee's decision.
"If he thinks it was a bad tackle, and straight red it is because it was.
"If the referee made a mistake, it is not because he wanted to do it, it is because it was a mistake.
"If he thinks it was a red card, it is done, and we cannot do anything about it."
