Barnsley strengthened their grip on a play-off place with a fantastic 3-2 win over AFC Bournemouth on Saturday.
The Reds took the lead through Michal Helik but the hosts led 2-1 at half-time.
Barnsley then produced a tremendous second half performance with Dominik Frieser levelling before substitute Carlton Morris won it.
The Reds are now unbeaten in 11 games and five points clear in the top six with ten games remaining.
They have won four successive away games for the first time at this level since 1996 and the first time in the second second tier season since 1925.
Valerien Ismael made two changes from the team that drew 0-0 with Derby County on Wednesday, with Jordan Williams making his first start under the head coach in place of Callum Styles and Dominic Frieser replacing Daryl Dike.
Bournemouth dominated the ball for ten minutes but began to be disrupted by Barnsley who tackled and intercepted well. The visitors took the lead in the 16th minute when Alex Mowatt's left-wing corner was flicked on at the near post by Mads Andersen and volleyed home almost on the line by Helik. It was the centre-back's sixth goal of the season.
The lead lasted six minutes before goalkeeper Asmir Begovic released Junior Stanislas on the right who beat Williams and crossed low for Arnaut Danjuma to tap in from close range.
Dominic Solanke should have made it 2-1 on 28 minutes when meeting a lofted Jefferson Lerma pass on the right of the box but his volleyed effort appeared to be tipped onto the bar by Brad Collins. Lerma then had a shot in the box deflected over the bar.
Bournemouth began to take control of the game, looking fresher than their visitors who had played midweek game unlike the Cherries. The hosts had joy played passed between the Reds back three and wing-backs for their pacy and expensive attackers to run onto.
Solanke had another chance just before the break when he met a right-wing free-kick but headed wide from ten yards out.
The former England striker did put his side ahead seconds later when Danjuma ran onto a pass down the left and squared for Solanke to fire in from close range.
Ismael made a triple change at the break. Herbie Kane, Styles and Carlton Morris came on for Romal Palmer, Williams and Conor Chaplin.
Barnsley began brightly after the break with Mowatt and Kane testing Begovic from 25 yards but the goalkeeper saved both easily.
Collins then sprinted out of his box twice in a couple of minutes and did not get the ball either time. But, after making a good tackle to make amends on the first occasion, he watched nervously as Solanke's shot at an open goal from the right wing trickle across goal and wide.
The equaliser came just after the hour-mark when Cauley Woodrow's cross from the right of the box took a deflection but fell to Frieser ten yards out and the Austrian produced a fine finish into the bottom left corner.
Woodrow then fired just wide of the bottom right corner from 20 yards out.
Both sides then had headed chances as Cameron Carter-Vickers nodded off-target from a corner before Morris headed Mowatt's left-wing cross back across goal and wide.
Collins then came out of his box and missed the ball for the third time in the second half but Sibbick blocked a Danjuma shot.
Kane then saw a 20-yard free-kick saved by Begovic before substitute Dike flicked a low left-wing Mowatt cross which just evaded Morris in the six-yard box.
Morris then put the visitors ahead in the 80th minute with a superb header into the top right corner from a left-wing Mowatt free-kick.
