Dean Bowditch missed a penalty against his former team Yeovil Town as MK Dons suffered only their second League defeat of the season at stadiummk.
Bowditch had the opportunity to cancel out Gavin Williams' first-half strike for Yeovil - who were reduced to ten men five minutes before the break due to Dean Parrett receiving two cautions - from the penalty spot only to be denied by Glovers goalie Sam Walker.
Yeovil had their backs against the wall for the duration of the second half and with a point to protect defended valiantly with ten men behind the ball to prevent a flurry of chances - with Daniel Powell, Jay O'Shea and Daniel Powell all left frustrated - finding the back of the net.
A frustrating evening for the Dons ended with a straight red card for Stephen Gleeson when the midfielder was dismissed for violent conduct.
The Dons were depleted when they were held to a draw at Hartlepool at the weekend, but Bowditch was passed fit to play against the Club he spent two years with while Gleeson returned from suspension to partner Alan Smith in midfield.
A blow, however, came in the form of an injury to James Tavernier which meant Adam Chicksen stepped into the vacant right-back position.
Bowditch was eager to impress against his former side and did well to hold up the ball and allow Gleeson to pick up possession with acres of space around him. The Irishman played an intelligent dinked pass into the path of Jay O'Shea but the winger, who has found a regular starting berth for the first time since joining in the summer, got his angles wrong and his curling effort went over.
Although a little on the scrappy side, the early phases of the game were dominated by the Dons with Luke Chadwick drilling a shot wide as the home side saw more than their fair share of ball but struggled to create clear chances.
Chicksen did his best to inspire the Dons to break the deadlock when he was found in an attacking position on the right-hand side and rather than find a team mate nearby decided to run at the Glovers defence. The youngster didn't know when he was beaten and after getting past three players almost appeared to run out of steam as his hot fell wide.
While the Dons had been the better side it was Yeovil who were almost gift-wrapped a chance at goal when a rare sloppy pass from Gleeson was intercepted by Glovers' top goal scorer Andy Williams on the edge of the 'D'. Luckily for the Dons, David Martin was alert and was able to make a timely interception.
The Dons had another warning not to switch off when Dean Parrett fizzed a cross into a static Dons box, fortunately Mathias Kouo-Doumbe spotted the danger and made a brilliant clearance to prevent Lawson D'Ath finishing the move.
The centreback pairing of Paul Huntington and Richard Hinds were finding the marking of Bowditch difficult, particularly when he was able to glance a header, lacking power, across goal.
Yeovil almost played themselves into danger when Sam Walker's clearance produced a poor heavy touch by Hinds and the ball fell kindly for Powell. To Hinds' credit he made amends by hassling Powell as he got into the box before making a solid block.
However, it was the Dons who were punished six minutes six minutes before the break when the Glovers packed a punch on the counter-attack and finished off their first real chance of the game.
It was a tale of the Williams' on the pitch as Andy Williams burst down the right and got the better of Shaun Williams before hitting what looked to have been a bad shot, but in fact the ball found Gavin Williams on the left of the box and from a tight angle he was able to finish past Martin at the near post.
Their celebrations were short lived though, when Parrett clattered into Shaun Williams the midfielder was in trouble and just ten minutes after picking up a booking for a challenge on Gleeson the Glovers man was sent-off for his second caution.
The Dons began the second half in a similar fashion to the first - dominating the play and looking lively on the break but struggling to break the Yeovil defence.
The Glovers' ability to cause problems on the break ensured some nervy moments for the Dons especially when Andy Williams' through ball split their defence and seemed destine to find D'Ath, yet Martin once again timed his clearance to perfection to end the danger without causing hard to the Glovers man.
Robinson's men continued to pile forward, but with the Glovers down to ten men they were desperately clinging to their lead. Shots were peppered into their box with Powell,O'Shea and Chicksen all seeing efforts blocked by the Glovers backline before Smith, advancing into the box with a sight at goal, lifted a great opportunity to score his first Dons goal over the bar.
The pressure was beginning to tell and when a cross from Bowditch struck the arm of Luke Ayling - Lewington's cousin - referee Dean Mahareb pointed to the spot and it was formed Glover Bowditch who stepped up to take the penalty.
Having scored two penalties last month the forward would have been in a confident mood in front of the Cowshed, but as he struck his spot-kick to the left of Walker the Glovers goalie went the same way, the ball popped under his body yet was able to recover to stop the ball on the line and deny the Dons an equaliser.
It just wasn't falling for the men from MK1 when they were so desperate for it to do so. When Gleeson and Lewington combined on the left to deliver a wonderful cross into the centre of the box Powell was in a great position in front of goal, yet he went for a flamboyant volley only to blaze over.
The opportunities continued to fall for the Dons when Paul Slane, introduced five minutes from time, weaved his way through the box to find Smith who stabbed a shot goal-bound but Walker parried the shot and Bowditch was unable to turn home.
The night ended on a sour note for the home side when Gleeson was sent off and will now wait to hear from the FA on the length of his ban.
