Keane's third red card of the season has been heated debate on our message board, and with the midfielder set to miss the rest of the campaign with a five match suspension the club have decided to appeal the decision.
Keane raised his hands in reaction to a scuffle in Saturday's 2-0 triumph which saw the Millers sneak out of the bottom four in League One.
The club will now await a decision from the FA's diciplinary panel to decide Keane's fate.
