Bolton Wanderers fought back twice to earn a point after goals from Daryl Murphy and Joe Dodoo cancelled out goals from Marcus Forss.
After the Wimbledon striker had given the visitors the lead just before the interval, Murphy netted his fifth goal in five successive league games.
But another Forss goal appeared to have put the visitors on course for a victory before Dodoo’s last gasp strike earned a share of the spoils.
Wanderers manager Keith Hill made four changes from his side’s last outing with Yoan Zouma, Sonny Graham, Ronan Darcy and Joe Dodoo coming into the starting XI.
With Josh Earl suspended and Luke Murphy and Liam Bridcutt missing through injury, Hill was only able to name six players on the bench.
After a slow start, Remi Matthews had to make a save at the second attempt to keep out Max Sanders’ effort from long range.
At the other end, Joe Dodoo slotted in a dangerous looking through ball in to the path of Daryl Murphy but Dons keeper Nathan Trott got in to steal the ball away before the Irishman could get his shot on target.
Fellow Wanderers frontman Chris O’Grady used his strength to move away from Luke O’Neill before driving his shot wide of the mark.
The energetic Darcy displayed some tidy footwork to get away from his marker before seeing his threatening cross cleared by Ryan Delaney.
The visitors had a chance just before the half hour mark when Pigott headed Paul Osew’s centre wide of goal.
Moments later Adam Chicksen sent a cross into the box from the left-hand side which was nodded wide by Daryl Murphy.
Wanderers were controlling the game and Darcy’s pinpoint corner into the box saw Murphy reach it but the big striker was unable to guide the ball on goal.
Trott spared team mate Paul Kalambayi’s blushes when he had to dive at full stretch to keep out the defender’s attempted headed clearance from a Darcy free-kick.
Matthews’ comfortably gathered an O’Neill free-kick but the visitors found themselves a goal up through Marcus Forss who charged on to goal after being put through before placing the ball past the advancing Matthews.
Wanderers had a half chance to restore parity just before the interval but Trott managed to get hold of Murphy’s headed attempt.
Thibaud Verlinden replaced O’Grady during the interval as Hill made an attacking change to try and get Wanderers back in to the contest.
Wanderers resumed on the front foot, eager to get the goal they deserved.
Dodoo was thwarted by Trott who kept out the midfielder’s angled drive.
Wanderers got that elusive leveler through Murphy who stopped in with a powerful header off Darcy’s corner to give Trott no chance. It was the Irishman’s fifth goal in five league encounters for the Whites.
The visitors almost found themselves back in front five minutes later when Osew’s angled drive hit the side netting.
Wanderers were looking to get their noses in front and Dodoo attempted to divert Chicksen’s cross in to the goal only to see the ball go narrowly over the bar.
Wimbledon were looking to restore their advantage and Delaney headed narrowly over as he connected with Reilly’s corner.
Darcy was unfortunate not to put the hosts in front after he latched on to Murphy’s knockdown but the youngster narrowly steered the ball wide.
But the visitors inflicted a body blow when Forss grabbed his second to seemingly send the visitors away with the points.
But Dodoo hit an injury-time equaliser with his first goal in professional football.
