AFC Wimbledon 1-2 Stevenage
Jerome Okimo scored from the halfway to complete a second-half turnaround for Stevenage at AFC Wimbledon.
George Francomb's excellent header sent the Dons in ahead at the break but Jamille Matt levelled things up before the shocking moment arrived from Okimo.
The full back saw his long punt up field bounce over Ben Wilson, who had an erratic game at Kingsmeadow, secured the points for Boro.
Neal Ardley made just one change to the side that held Leyton Orient last time out as the suspended Barry Fuller was replaced by Callum Kennedy.
Chief executive Erik Samuelson took to the centre circle before kick-off to address the crowd after the historic news just 48 hours earlier as it was confirmed the club would be returning to Merton.
His presence got the supporters in the mood and the Dons did start brightly, although neither keeper was tested in an opening 20 minutes short on quality but not lacking endeavour.
Wimbledon's Wilson was the first of the two men between the sticks to be tested as he scrambled across the line to palm away Michael Tonge's swooping free-kick.
Stevenage were growing in confidence and former Wealdstone youngster Tom Pett was next to try his luck as the No 11dodged a couple of tackles before firing in a low drive.
Ardley's boys finally called Chris Day into action with 10 minutes of the half remaining but it was a scuffed attempt from Lyle Taylor and the deadlock remained unbroken.
A couple of rash moments from Wilson, who came rushing out to clear but could only find a red and white shirt, almost allowed the visitors to grab a half-time lead but they couldn't hit the target.
But it was the Dons who went in ahead as Dannie Bulman whipped in a lovely cross from the left and Francomb darted in to power in a wonderful header at the far post.
Teddy Sheringham stormed down the tunnel at half-time and must've had strong words for his team in the dressing room as the came out with renewed purpose.
And 10 minutes after the restart big striker Jamille Matt cut inside his marker on the edge of the area before bending a stunning strike into the top corner to pull Boro level.
They nearly had the lead moments later but they couldn't force the ball home from the mother of all goalmouth scrambles that left Karleigh Osborne and Paul Robinson needing treatment.
It wasn't Wilson's best afternoon in the Dons goal but things were about to get worse for the on-loan Cardiff City starlet.
Stevenage took the lead in the most bizarre fashion as Okimo launched a free-kick from inside his own half that was allowed to bounce and it deceived the keeper and somehow found its way in to send the travelling fans home happy.
