Michael Collins' first-half strike looked to have given the Terriers all three points at Edgeley Park on Saturday, but as the clock ticked towards stoppage-time, Huddersfield defender Nathan Clarke could only divert Leon McSweeney's angled drive past the helpless Alex Smithies.
The point leaves Huddersfield six points outside the play-offs in League One but Clark said: "It was frustrating to concede right at the end, the players had stuck to the game plan and executed it well throughout the game.
"One lapse has cost us, and because of that it feels a bit like we've just suffered a defeat.
"We've got two home games to come now, and it will be good to get back in front of our own fans and the atmosphere there.
"The play-offs are still a possibility for us, of course they are. We've still got 13 games left, so that's 39 points that are still up for grabs. There's plenty of points left to play for, so let's see where we go from here."
