Dartford 1-2 Luton Town
Dartford missed the change to climb out of the Conference Premier relegation zone as they conceded two late goals to lose to leaders Luton Town.
Luton's Matt Robinson saw his header hit the post, before Mikel Suarez's header put Dartford ahead.
The game turned when Dartford had Kenny Clark sent off for late challenge on Alex Lawless.
Pelly Ruddock's 20-yard strike drew Luton level and Andre Gray's header from Ronnie Henry's cross won it.
Luton stay 13 points clear at the top of the table and now need just three more wins to secure the title, and a return to the Football League after a five-year absence.
Dartford manager Tony Burman told BBC Radio Kent:
"I'm delighted with the way we've performed. We defended for long periods but I felt we were reasonably dangerous on the break.
"Alan [Julian] hasn't made that many saves but the sending off changed the game.
"It's knocked us. We need to have 11 players against a team like Luton. I'm disappointed with the decision.
"I'm standing close to it. The referee is not standing close to it, he's behind them. There's no way that he can see that that's a sending off."
