MK Dons boss Karl Robinson will appeal midfielder Stephen Gleeson's red card after Sunday's 3-2 play-off semi-final first leg win at home to Peterborough.
Gleeson was dismissed by referee Jon Moss in a contentious penalty decision with nine minutes remaining after he brought down Mark Little at the end of a lung-busting run. There appeared to be little contact and the consensus after the game was that any foul was also outside of the penalty area.
"Gleeson should have brought him down earlier on and taken a booking but he was too honest," said Robinson after Posh captain Grant McCann kept his cool to send David Martin the wrong way and set up the second leg at London Road perfectly.
"There was then a tangle of legs two or three yards outside the area with two players covering. It was a foul but it was never a penalty so we will appeal it, 100%. I hope the FA have a look at this instantly and I am sure they will make the right decision."
Posh led at half-time through striker Craig Mackail-Smith's 35th goal of the season but fell apart in a calamitous spell after the break.
England Under-21 international goalkeeper Joe Lewis came off through injury during the interval and replacement Paul Jones was beaten three times in the opening 11 minutes as Daniel Powell, Sam Baldock and Angelo Balanta seemingly put Robinson's side in charge. Posh full-back Charlie Lee was then sent off before Gleeson walked and McCann slotted home.
Peterborough manager Darren Ferguson conceded his side were fortunate to still be in the tie and also felt they were lucky to be handed the late penalty.
He said: "The performance was as bad as we could have played in a game like this. It was the wrong day to pick to play so poorly and I am delighted to still be in the tie. We made a perfect start but we lacked composure.
"Credit to Milton Keynes, they were far better than us and at 3-1 down with 10 men you take what you can. It looked far more likely to be 4-1 than 3-2 at one point. We lost two of our back five which was key but you get injuries in football and the goals we lost were very poor.
"We don't know the extent of the injuries but we will have to deal with it. Apparently our penalty was four yards outside of the box so we may have had some luck there but you need that in games like this."
