SHANE Lowry will serve a four-match ban after the Football Association refused to overturn his sending off against Sheffield Wednesday.
Lowry was sent off during Tuesday's 1-1 draw for an alleged stamp on Giles Coke.
However, replays show that Lowry was attempting to free the ball from between Coke's legs after a foul, rather than to injure his opponent.
"I am disappointed for Shane," boss Ian Holloway said. "We tried to appeal his red card, but they have absolutely, totally dismissed us with the arrogance they've got.
"It's unbelievable how they can sit there and say the referee and linesmen are never wrong.
"I cannot help their player's reaction to what Shane did. He tried to put his foot on top of the ball and get it back, and then their bloke threw him over.
"He's actually stepped on the ball and dragged it back with his foot, not stamped on him. It was not aggressive.
"I thought he had been sent off for his retaliation because I did not believe he was the one who started it.
"Their player should not have reacted like that – he might have been menopausal, I don't know. He's got to be crazy to respond like that at Millwall.
"Going through the process of appealing drove me insane yesterday. I think the referee lost control of the game.
"I'm a bit angry about it but such is life. Normally that referee is very good, I must admit.
"We've also been charged by the FA for being involved in a mass brawl. I thought 95 percent of the players who got involved were trying to calm things down."
