Dons boss Karl Robinson blasted defender Antony Kay for picking up two needless bookings in their defeat to Crewe, earning him another three-match ban.
After taking the lead through Patrick Bamford’s first senior goal, Mathias Pogba’s double won it for the Railwaymen 2-1 at Gresty Road.
Despite looking the better team for an hour, Dons failed to capitalise, hitting the woodwork three times before Kay’s slip six minutes from full time allowed Pogba two bites of the cherry to slot the winner past a hapless Ian McLoughlin.
And the defender’s misery was compounded when he picked up his second booking in the last minute, sending him in for his third early bath of the campaign.
After the game, Robinson admitted that he felt let down by the 30-year-old.
“The sending off was an embarrassment to Antony Kay,” he said. “I’ve backed him in the past and there has been decisions I’ve defended him against, but they were two blatant yellow cards.
“He knows how difficult things are at the moment.
“He has let me down, he has let his team-mates and most importantly, he has let the fans down.”
Kay will serve a three match ban as a result of his dismissal, meaning he’ll miss games against Colchester, Hartlepool and Brentford.
But Robinson didn’t the lay blame entirely at Kay’s door. Describing the last half an hour at Crewe as ‘a shambles’ he said that the players who weren’t committed to getting Dons into the play-off spots would be shown the door in the summer.
Robinson said: “The last 30 minutes was nothing short of embarrassing. I have to hold my hands up and accept that we were very, very poor.
“I have never minced my words, and I’ll admit when I’ve got things wrong, but that was a shambles.
“Some of them won’t be playing for the football club next season. I’ll be here. But if they put in performances like that, then they won’t be here, because it’s not acceptable.
“When you finish a game like that, it’s not acceptable. If I have to take responsibility for the season, then so do the players.
“And if they can’t take responsibility, then they’re in the wrong industry.”
