Substitute Patrick Agyemang grabbed a share of the points for Wimbledon as the South London derby with Millwall ended level.
He beat goalkeeper Tony Warner for the simplest of goals on 47 minutes.
David Connolly, who was replaced by Agyemang at half-time, had put the visitors ahead after 20 minutes.
But Tim Cahill and Steven Reid struck to put the visitors into a 2-1 interval lead.
Both sides had recorded back-to-back victories in the run up to their first league meeting in over a decade.
Wimbledon roared out of the blocks, with teenager Joel McAnuff the first to go close.
The pacy winger ran unchallenged through the middle before cannoning a vicious 25-yard drive off the right-hand upright.
Moments later the Dons were in front. Jermaine Darlington beat full-back Matt Lawrence to the byline down the left before whipping in a dangerous cross.
Republic of Ireland striker Connolly was on hand to nip in front of his marker and nod home at the near post.
Millwall fought back strongly, scoring two goals in a three minute spell against the run of play just before half-time.
First Connolly's Irish team-mate Reid surged down the right to float a searching cross into the far post.
Towering Cahill buried his header past despairing goalkeeper Kelvin Davis.
The two forwards reversed roles moments later when Millwall won a free-kick deep in Dons territory.
Cahill played the ball to Reid 25 yards from goal and the winger fired an unstoppable shot past Davis which silenced the home fans.
But the introduction of Agyemang after half-time immediately changed the course of the game.
A neat passing move within two minutes of the re-start culminated with promising youngster McAnuff running at the Millwall defence.
He slipped the ball through to Agyemang who sneaked in behind his marker, beat keeper Warner and slotted home from close range.
Wimbledon then enjoyed a brief period of ascendancy before Neil Harris, making his second appearance after his comeback from testicular cancer, entered the fray for tiring veteran Steve Claridge.
But Millwall failed to convert their second half chances, and it was Wimbledon who forced the best save of the match from visiting keeper Warner.
A weak header out of defence by David Tuttle was pounced on by McAnuff who ran at his man and fired a blistering shot toward the top corner.
But Warner was equal to the effort and tipped acrobatically over the bar for a corner.
