More than 1,000 AFC fans were second time unlucky at the home of the biggest rivals.
AFC got nothing out of the first historic meeting with the so-called Franchise FC in 2012, and they got nothing out of this too.
In fact, they were left to count the cost after a bad injury to defender Jack Smith.
The full-back mixed with MKD’s Danny Green and came off worst in a full-blooded challenge on 10 minutes.
Smith lay prone for a full more three minutes before he was stretchered off in distress ominously holding his shoulder, but suffered what turned out to be medial ligament damage.
Matt Tubbs came close with a low from inside the box but David Martin pushed away.
And having in all truth dominated the first 19 minutes, MK took the lead from a corner when Kyle McFadzean converted with a clever flick of his heel past a stranded James Shea.
A mis-headed clearance from Ben Reeves on the stroke of half time saw Rigg flash the ball across the box with Tubbs only a toe poke from levelling.
The last thing AFC needed arrived after just four minutes into the second half.
A drive forward from Lee Hodson picked out Daniel Powell and he smacked a shot from outside the box – and again beat Shea at his near post.
Matt Tubbs converted a very late penalty to herald a mini pitch invasion like the game two years ago, but there was no time for anything else.
