Leeds United regained top spot in the Championship following a 1-0 victory over Middlesbrough.

Daniel James scored the only goal after just two minutes at the Riverside Stadium, where the hosts' play-offs hopes suffered a blow.

The Wales international made the vital contribution with his 12th goal of the season, though Leeds also had two goals disallowed for offside.

Nevertheless, Daniel Farke's side dug deep in the second half to ensure they returned to the summit on goal difference ahead of Burnley.

The Clarets surrendered top spot after they were held to a goalless draw by lowly Derby County.

Scott Parker's side could not find the breakthrough at Pride Park, where the hosts held on to remain outside the relegation zone on goal difference.

Sheffield United missed the chance to leapfrog Leeds and Burnley to top spot, after they were beaten 1-0 by play-off hopefuls Millwall.

It was a second successive defeat for Chris Wilder's side, with Josh Coburn scoring what proved to be the winner in the 21st minute at Bramall Lane.

Elsewhere, Haydon Roberts struck a stoppage-time winner to move Bristol City up to fifth place after snatching a dramatic 2-1 win over 10-man West Bromwich Albion, who had Jayson Molumby sent off.

The spoils appeared set to be shared at Ashton Gate, where Alex Mowatt cancelled out Nahki Wells' earlier effort.

However, with the Baggies reduced to 10 men after Molumby was dismissed for a late challenge on Joe Williams, Roberts stole victory for the hosts in the 96th minute. 

While the Robins boosted their hopes of a top-six finish, Sunderland secured their place in the play-offs following a goalless draw with Norwich City at Carrow Road.
