Championship round-up: Leeds back on top as Burnley and Sheffield United stumble

Both teams had first-half goals ruled out for offside - Leeds controversially so - and despite a dominant display from the visitors, Boro sparked into life after the break, coming close through Finn Azaz and Delano Burgzorg.

Leeds had a second goal of the evening disallowed for offside after Patrick Bamford found the net against his old club, but they managed to see the game out to return to the Championship summit, while Boro remain in the mix for a play-off spot.

The visitors struck only two minutes in when Manor Solomon broke down the left flank before playing a low pass across the six-yard area, where James managed to fend off Samuel Iling-Junior to stab home as the ball hit the arm of goalkeeper Mark Travers before bouncing over the line.

The visitors stretched their unbeaten streak to 28 games at Pride Park, while a point on the road against resurgent Derby keeps them in the top two in their quest for a return to the Premier League.

Josh Coburn's first-half strike clinched play-off chasing Millwall a 1-0 win at Bramall Lane and dented Sheffield United's automatic promotion chances.

Millwall turned in one of their best away displays of the season to frustrate the Blades and Coburn's thumping finish lifted the Londoners to within three points of the top six with five games to play.

Blades substitute Jesurun Rak-Sakyi twice went close to equalising while Chris Wilder's side, who slipped to their eighth league defeat of the season, created a string of scoring chances.

But the Lions, for whom Mihailo Ivanovic should have doubled his side's lead, turned in a never-say-die defensive display and were a constant threat on the counter.

Substitute Haydon Roberts fired a last-gasp winner as Bristol City strengthened their play-off bid with a 2-1 win over a West Brom side who finished the game with 10 men.

The home side went in front after 56 minutes when Nahki Wells turned his marker on the edge of the box and arrowed a low right-footed shot into the bottom corner.

But Albion were level six minutes later when Alex Mowatt capitalised on a collision between advancing goalkeeper Max O'Leary and defender Cam Pring to shoot unchallenged into an unguarded net.

The Baggies had Jayson Molumby sent off for clattering into City substitute Joe Williams after 89 minutes and conceded in the last of five minutes of stoppage time when Roberts' low shot from 10 yards squeezed between the legs of Albion goalkeeper Josh Griffiths.
