Northampton Town manager Chris Wilder was left to reflect on a third home game running when his relegation-threatened side has failed to overcome 10 men.
Sammy Moore grabbed the stoppage-time equaliser as AFC Wimbledon came back to draw 2-2 at Sixfields.
Darren Carter's fifth goal of the season looked to have earned all three points for Cobblers, having earlier equalised from the penalty spot after Jack Midson was sent off for handball.
That cancelled out George Francomb's early opener and Carter's second goal on the night put Cobblers ahead only for Moore to grab the stoppage-time equaliser.
Wilder said: "We have to be careful that people don't give up on us and I know myself and none of the players will give up.
"Some people will want to after a result like that and don't get me wrong, I know it's a massive missed opportunity. We need to show character now and I'm certain that I've got that in the dressing room.
"We're two points off a couple of sides now and there are seven games left so there are 21 points still to play for but it felt like a defeat.
"We didn't sit back but Wimbledon defended superbly with 10 men, they sat deep and got their blocks in, so it was hard for us."
Wimbledon boss Neil Ardley was delighted to see his side produce another late comeback for the second game in succession.
He said: "To be honest there's no way we would have deserved to have lost that game. Anyone who says that we did is fooling themselves.
"We were resilient in the second half, we stayed in shape and the players did everything we asked of them. We thoroughly deserved to get something from the game and I think all of the fans will be going home proud of this team.
"For the penalty, Jack [Midson] admitted it hit his hand, he didn't handball it but it hit his hand. But even with 10 men we limited them to very little in the second half; if we'd lost it would've been very harsh on us."
