Kevin Lisbie struck a dramatic 90th-minute equaliser to ensure justice prevailed as Millwall shared the spoils with Sheffield United.
The Lions had looked to be comfortably in control of proceedings until referee Darren Deadman astounded the travelling camp by awarding the Blades a highly controversial penalty 13 minutes from time when sub Daniel Bogdanovic went to ground with no contact appearing to be made by skipper Paul Robinson.
Bogdanovic picked himself up, dusted himself down and thumped home the resulting spot-kick with clinical presicion into the bottom right corner.
But full credit to Kenny Jackett's bravehearts who battled back and grabbed a late goal for the second successive match courtesy of Lisbie's low finish from a James Henry corner.
"It was such a bad penalty decision it was embarrassing," fumed Jackett. "There was no contact and it was not a penalty.
I was pleased with the way we came back and it was a good goal by Kevin Lisbie, who has done well for us and earned some important points recently."
The goal was the least Millwall deserved as they strived to gain their first away win since securing a 1-0 success at Middlesbrough in November.
United, themselves desperate for their first win since 18th December, started with purpose and Lions keeper David Forde was called into action on six minutes with a smart stop from Marcus Bent's 18 yard drive.
Forde then produced a brilliant save just two minutes later to deny Mark Yeates, who having seen his initial free-kick blocked by the defensive wall, rifled a half-volley towards the bottom corner only to be thwarted by the fingertips of Forde.
Referee Deadman, who really didn't enjoy the best of games, brandished cheap yellow cards to Jimmy Abdou (14mins) and then Steve Morison (16mins) adding to a bitty, frustrating opening period for the visitors.
However Jackett's charges slowly but surely settled into the game and started to ask questions of the home defence, carving out a couple of decent opportunities themselves before the break.
Liam Trotter had a low drive saved by Steve Simonsen following some neat footwork by Danny Schofield before a nice move down the left involving Theo Robinson and Trotter created an opening, but Blades skipper Nick Montgomery was there to mop up the loose ball for a corner.
It was from another corner - The Lions fourth of the opening half - that captain Robinson's header was parried by the keeper and namesake Theo's flicked return header landed straight into Simonsen's hands.
At the other end a low drive from Michael Doyle flashed a yard wide for the hosts before play swung back Millwall's way and some fantastic footwork and determination by striker Robinson took him powering through the United rearguard. He then whipped over an inviting cross that had a touch too much pace for Schofield, and his header from close range flew over the bar.
It was the turn of Trotter to head narrowly over from another Henry corner 12 minutes into the second-half for a Millwall side that had comfortably got the measure of their opponents by this stage.
So much so that Blades boss Micky Adams made a double substitution to try and liven his side up. But little could he have dreamed that it would be the generous intervention of referee Deadman that would give his side a huge helping hand.
There seemed to be minimal danger when Bogdanovic worked his way into the danger zone, shadowed by Robinson, only for the Blades sub to go to ground in quite dramatic fashion with no contact appearing to be made at all by the Millwall man.
It was as perplexing a penalty decision as it was infuriating and with one crisp kick of the ball from the resulting penalty kick Bogdanovic looked to have put his side within reach of three crucial points.
However spurred by a sense of indignation and injustice, The Lions roared back. An audacious piece of skill by Scott Barron nearly paid off, only for his final cross to be cleared as Millwall pressed forward.
Then on 89 minutes a superb crossfield pass from Darren Purse picked out Neil Harris on the right, his first-time delivery was met by Lisbie with the latter's drive deflected wide for a corner.
It was from this, with the clock creeping into the first few seconds of injury-time, that Henry despatched another pinpoint delivery, the ball spun past Trotter and found Lisbie, who made no mistake with a crisp low finish into the back of the net.
Thereafter it was The Lions, encouraged by over 1,000 travelling fans crammed in the Bramall Lane end, who pushed on for victory, and they came so close in the dying seconds when Lisbie met a superb Henry cross from the right and headed agonisingly over.
