MILLWALL boss Neil Harris confirmed the club will appeal Mahlon Romeo's sending-off in the 2-1 win against Gillingham on Sunday afternoon.
The Lions defender was visibly upset after he was shown a straight red card by referee Paul Tierney, who deemed Romeo's 86th-minute challenge on Brennan Dickenson was reckless.
The 20-year-old could now be ruled out of the play-offs.
Harris told the media after the victory at Priestfield: "I thought it was harsh, he went in for the ball and at the time I thought it wasn't a red card. Having looked back I can see how, from the referee’s angle, he thought it was a bad tackle.
"It clearly shows there is no contact on the player, it clearly shows he goes for the ball so we will certainly be appealing it.
"There is no contact and you have to put it into the context the game itself. The atmosphere was hostile for my players.
“We will see what we can do and find out in the next few days if our appeal is successful."
Harris also found himself in trouble with referee Tierney after Romeo's sending-off, but he insisted he had only wanted an explanation for the red card.
"I shouted 30 yards across the pitch to the referee, I wanted him to come and tell me why he sent Romeo off," Harris said.
"He thought I was being hostile towards him and he sent me to the stand. I've seen far worse, ten times a game.
"I thought it was harsh on myself, and again I'll speak to the referee and make sure he knows there wasn't anything malicious from myself – I was just protecting my player."
