John Egan's goal in the final seconds rescued a point for promotion-chasing Sheffield United in a 1-1 draw at QPR.
The Republic of Ireland international atoned for a terrible mistake which handed Rangers an early lead at Loftus Road.
Ilias Chair's fortuitous opener after 11 minutes - the Morocco international's fourth goal of the season - was a much-needed boost for Rangers following four consecutive home defeats.
After defender Egan gave the ball away while trying to play out from the back, Chris Willock teed up Chair, whose shot deflected off Egan, completely wrong-footing goalkeeper Wes Foderingham.
But the home side were unable to hold on for what would have been Neil Critchley's first home win since taking over as R's boss.
After fellow Irish international Enda Stevens' cross from the left was half-cleared back to him, he headed the ball towards Egan, whose close-range shot deflected in off Rob Dickie.
Burnley strengthened their position at the top of the table as a 2-1 win at Swansea made it six league victories in a row for Vincent Kompany's side.
Ian Maatsen fired Burnley into a 2-0 lead with two fine goals in the space of 10 first-half minutes, and although Ollie Cooper pulled one back in the 27th minute, the Clarets hung on for three more points in their pursuit of promotion.
Maatsen opened the scoring with a free-kick in the 12th minute, with two Burnley men infiltrating the wall and quickly making space for the Dutchman to beat Steve Benda with a shot off the left-hand post.

The second was even better as Maatsen took the ball from Nathan Tella on the edge of the area and unleashed a powerful shot which left Benda with no chance.
Cooper got his fourth of the season when Aro Muric fumbled a Jay Fulton shot, but Swansea saw penalty appeals waved away when Joel Latibeaudiere went down in the box and could not find a leveller.
Josh Cullen played the entire game for the visitors, while Ryan Manning did the same for the hosts.
Watford moved up to fourth as substitute Vakoun Bayo grabbed a late goal to defeat Norwich 1-0 at Carrow Road.
The Hornets put back-to-back defeats behind them as Bayo finished off a swift counter-attack with three minutes left against the managerless Canaries.
Adam Idah played full game for Norwich, while Andrew Omobamidele got the last 15 minutes in his second appearance since his return from injury.

Darragh Lenihan featured for Middlesbrough, who are only a point behind Watford in fifth place after securing a sixth win in seven, beating Birmingham 3-1 away from home.
All the goals came in the second half, with Matt Crooks scoring two in three minutes before setting up another.
Crooks was unmarked to head in Jonny Howson’s cross in the 57th minute, and seconds later he pounced on a mistake from George Friend to add a second.
Although Tahith Chong pulled one back, Crooks then played in Chuba Akpom to make sure of the points for Michael Carrick’s side.
West Brom moved to within a point of the play-off places as Daryl Dike’s 60th-minute goal was enough to beat Reading 1-0 and make it eight wins from their last nine.
Jayson Molumby and Dara O'Shea both featured for the Baggies, with Molumby whopping in a cross from the right for the game's only goal. Jeff Hendrick got just over 80 minutes for Reading, and Shane Long came on for 20 minutes at the end.
Albion fans continued their protests against controlling shareholder and chairman Guochuan Lai off the pitch, but will have been encouraged by events on it as Dike got his first home goal after a string of injuries.

Rock-bottom Wigan suffered a third 4-1 defeat in the space of seven days as Hull moved away from danger with victory at the DW Stadium.
Hull led with 17 minutes gone through Jacob Greaves and should have added to their lead before substitute Nathan Broadhead levelled for Wigan, from a James McClean corner, just after the hour.
But after Hull regained the lead with 12 minutes left via a deflected strike from Oscar Estupian, Wigan imploded with Tyler Smith scoring twice late on.
Cyrus Christie got just over 80 minutes for Hull, while former Cork City defender Sean McLoughlin provided the ball over the top for Smith's superbly taken goal - Hull's third.
Ched Evans headed in a winner in the third minute of time added on, with Alan Browne providing the assist from a corner, as Preston snatched a 1-0 victory at Stoke in a game that had seen kick-off delayed due to traffic problems in the area.
In League One, Conor Hourihane and David McGoldrick (penalty) were on the mark as Derby County defeated Accrington Stanley 4-0, and so remain in the play-off positions.
