The Millwall midfielder now faces a 4 match ban and possible further sanctions after failing to leave the pitch after his dismissal. He faces a new misconduct charge which could see his ban raised.
Millwall did not appeal against Dave Livermore's sending off and neither did City after James Collins saw red.
It's uncertain if City will face any action against them for the incidents that occured as the game came to a close. The FAW were waiting for the referee's report before deciding.
