Leeds lose at Millwall as another stalemate stalls Sunderland
Neither Leeds United nor Sunderland could claim three points at the top of the Championship on Wednesday, with Millwall now the form side.
Leeds United suffered a first away defeat since April at Millwall as they lost ground at the top of the Championship, although leaders Sunderland could only draw again.
Daniel Farke's Whites required a response to move back into the automatic promotion places after a win for Sheffield United on Tuesday, but instead they were beaten 1-0 by surprise package Millwall.
A fourth straight 1-0 win for the Lions was secured with a first-half Japhet Tanganga goal and moved them up to fifth, now just four points behind Leeds in third.
Leeds are themselves four points behind front-runners Sunderland, but that gap could have been wider had the Black Cats beaten Preston North End.
Just as at Queens Park Rangers on Saturday, though, Sunderland were held to a goalless draw away from home.
Jobe Bellingham was sent off against QPR and so missed out through suspension, and further bold changes from coach Regis Le Bris could have opened the door for Preston to snatch an unlikely win.
Instead, Preston remain among a clutch of teams just above the relegation zone, also including Luton Town and Cardiff City.
Luton beat Cardiff 1-0 with a Jacob Brown goal, while Coventry City lost 2-1 at home to Derby County. Stoke City were 2-0 winners at Blackburn Rovers.
