Millwall boss Neil Harris “couldn’t believe it” when Jed Wallace was sent off against Burton.

The red card changed the game, which the Brewers went on to win 1-0 thanks to Marvin Sordell’s 70th-minute goal. The result leaves the Lions just five points above the drop zone.

Referee Tony Harrington’s decision to give Wallace his marching orders for a late challenge on Tom Flanagan was very harsh, but at the moment, Harris is unsure if the club will appeal it.

He said: “It’s a poor challenge, it’s a yellow card at least. What’s the rule? No one seems to know. Was it a dangerous tackle or not? I need to see it on the big screen.

“Jed’s late, it’s definitely a foul.

“The boy hasn't made a meal of it. It changed the game. It gave Burton inspiration and a positive mindset because before there was only one team trying to win the game.

“It’s a poor goal for us to concede.

“I haven't spoken to the referee. I think I’ve been in to see eight or nine referees this year. What’s the point? If we look at it and feel it’s appropriate to appeal then we will.

“We won’t make a rash judgement on the decision. In the heat of the moment I couldn't believe it - I thought the referee pulled out the wrong card.”

The Lions were on top before the game’s controversial moment.

Aiden O’Brien and Wallace wasted golden opportunities to give the hosts the lead, before Lee Gregory hit the post with the last kick of the game.

Harris has bemoaned his attacking players’ wastefulness in front of goal.

He added: “I keep saying after every game we should be more clinical.

“Our forwards, not good enough. Our attacking players with chances, not good enough.

“We've been in every game this year. People need to take responsibility - we should've been out of sight.

“I’ll go back to the first game of the season against Nottingham Forest. We had 24 shots on goal and didn't score - people need to take responsibility.”
