Nahki Wells struck late as 10-man Huddersfield earned a deserved point from a 1-1 draw with MK Dons on Tuesday evening.
Alex Revell's first Dons goal looked like being enough for the home side, especially when Town substitute Philip Billing was sent off just four minutes after coming on at half-time.
But the Terriers refused to buckle and were rewarded with an equaliser four minutes from time.
The nervy Dons were booed off by some fans, as they had been on Saturday after a dismal 2-0 home defeat at the hands of fellow strugglers Bristol City.
Goalkeeper David Martin had been injured against the Robins so that opened the door for American shot-stopper Cody Cropper against a Town side that had eased its own relegation worries with back-to-back victories over Nottingham Forest and Wolves.
Cropper, making his first ever league start, did well to gather early on as Karim Matmour closed him down at pace before Wells fired over his goal from Huddersfield's next attack.
The Dons replied with a move down the left that saw Jonny Williams denied at his near post by Town keeper Jed Steer, who was then required to get behind a long-range effort from the same opponent.
Again Steer was needed to preserve parity, this time to keep out Revell's drive, and defender Martin Cranie threw himself in the way of Dean Bowditch's follow-up effort.
But the Dons did take the lead in the 28th minute from the best move of the game, Revell heading home Williams' delivery from the right after some slick passing in the build-up.
The Terriers made a double change at the break with Elvis Manu and Billing replacing Joe Lolley and Harry Bunn.
But Billing lasted just four minutes before being shown a straight red card for a challenge on Forster-Caskey that was high but did not look malicious.
Josh Murphy curled a couple of free-kicks wide as the Dons tried to take advantage, while Forster-Caskey went in hard on Wells but escaped even a booking, to the Town fans' disgust.
Rob Hall replaced Murphy for the home side, who saw Steer stretch to gather a back-header from team-mate Matt Hudson.
Cropper had to tip a fierce drive from Wells over and Town appeals for a handball offence from the corner went unheeded by the referee.
Williams was given a deserved ovation when Nicky Maynard came on to replace him for the final 15 minutes.
Joel Lynch then came on for Town and they deservedly levelled with four minutes remaining.
Tommy Smith launched the ball upfield, Hudson flicked it on and when the Dons defence dithered, Wells was there to loft over Cropper and earn a share of the spoils.
