Charlton conceded a goal in stoppage time and dropped two points at Kingsmeadow on Saturday.
Ricky Holmes had given the Addicks an early lead with a free-kick, and looked set for three points.
Jorge Teixeira partnered Patrick Bauer at the heart of the defence, with Ezri Konsa moved into midfield. Konsa replaced Jake Forster-Caskey, who was ruled out with an ankle injury.
Tony Watt dropped back to replace the suspended Nathan Byrne, and Lee Novak was the lone striker. Josh McGennis was on the bench.
Holmes put Charlton ahead after eight minutes, when he curled a free-kick over the wall and into James Shea’s top right hand corner. The free-kick was awarded for a foul by Chris Robertson on Joe Aribo.
There was an astoning seven minutes of time added at the end of the first period due to numerous injuries, and a delay when the assistant referee was struck on the head by an object.
Addicks fans spilled over onto the walkway at the front of the terrace in an attempt to see the game. The terrace seemed very overcrowded.
Wimbledon started the brighter after the break, and went on to have the lion’s share of possession, but the best chances of the half fell to the visitors.
On the hour mark, Watt drew a fantastic save from Shea, and with just the keeper to beat, Novak fired into the side netting, when he should have done better. The visitors also had a decent penalty shouit for handball waved aside.
Josh Magennis made his comeback, replacing Novak after 57 minutes, and Stephy Mavididi made his debut ten minutes from time.
The Wombles fans behind the goal iunfurled an unsavoury banner about Karl Robinson late on.
Charlton appeared to be seeing the game out, but were foiled by Tom Elliott’s late, late volley. The striker was dismissed after picking up a second yellow card for his goal celebration.
It is a result that will leave Robinson hugely frustrated.
