Leicester missed the chance to go four points clear at the top of the Championship after a 1-0 loss at Millwall.

Ryan Longman’s brilliant top corner finish was the difference for the Lions, who climbed into 17th.

Leicester stayed one point clear at the summit after Leeds moved into second following a goalless draw against Sunderland.

Substitute Milutin Osmajic bagged a quickfire hat-trick as Preston completed an incredible second-half comeback to beat relegation-threatened Huddersfield 4-1.

Josh Koroma handed the Terriers the lead in the 42nd minute, but Preston equalised when Will Keane levelled from the penalty spot.

Osmajic starred from the bench in the final stages, striking twice in three minutes before completing his treble in the second minute of stoppage time to snatch three points and leave Town outside the bottom three on goal difference.

Sheffield Wednesday scored two late goals to salvage a crucial point in their relegation battle after a 2-2 draw against Norwich.

The visitors struck quickly in the opening stages with Josh Sargent putting the Canaries ahead in the 11th minute before Borja Sainz doubled the advantage five minutes later.

However, Wednesday turned the game around in the final 15 minutes with Michael Ihiekwe pulling one back before Michael Smith levelled in the 85th minute to leave them alongside Huddersfield.

Fourth-placed Southampton continued their play-off push with a 2-1 win against Coventry.

Haji Wright missed a penalty for the Sky Blues in the 10th minute and Southampton struck just eight minutes later through Kyle Walker-Peters.

Che Adams doubled the lead just before the break before Jake Bidwell pulled one back for Coventry, who remain just outside the play-off places.

Plymouth earned a valuable point after drawing 1-1 with QPR.

Sam Field put the visitors ahead from a corner, but Argyle are two points above the drop zone as Albert Adomah turned the ball into his own net.

Leicester boss Enzo Maresca expects plenty more twists in the Championship promotion race.

The Foxes suffered a wobble in their bid for an instant return to the Premier League after a stunning Ryan Longman strike condemned them to a 1-0 defeat at struggling Millwall.

Back-to-back wins had reignited their promotion bid and lifted them back to the top of the pile.

But, while Leeds could only pick up a point at home to Sunderland and stay second, third-placed Ipswich can climb above both if they beat Watford on Wednesday.

“It was a tough night, in the first half we struggled on the ball, we were not clean,” said Maresca.

“They defended very well. We expected in the second half to find more space but they scored a fantastic goal.

“Now is not the time to think too much. Tonight is gone.

“The last games are more or less similar for all the teams. Clubs are trying to survive or go up, the intensity is higher. It’s a problem for us, but for every club.

“If you watch the table yesterday, and tonight, and in two days, you’d go crazy. We have to go game by game.”

The goal arrived on the hour after Wout Faes lost the ball in midfield and Billy Mitchell sent Longman scampering away down the left.

The on-loan Hull winger cut inside Harry Winks before curling a spectacular 25-yard effort past Foxes goalkeeper Mads Hermansen and in off the underside of the crossbar.

Kelechi Iheanacho had the chance to rescue a point in stoppage time but his header was cleared from under the crossbar by Mitchell.

The Lions were in need of the points for different reasons and battled to a first win in five matches to go four points clear of the relegation zone.

Lions boss Neil Harris said: “Firstly, it’s so Millwall-like to lose to Rotherham and Huddersfield, both in the last minute, and then beat the league leaders.

“That’s what this club does. Not just this group. The last 30 years of Millwall Football Club.

“We scored a goal that would win any game at this level. I thought it was an excellent Millwall performance. To play against arguably the best team in the league and limit them to very little was so impressive.

“We’re moving in the right direction. What I’m seeing in the group is a lot of positives.”

Leicester suffered a wobble in their bid for an instant return to the Premier League after a stunning Ryan Longman strike condemned them to a 1-0 defeat at struggling Millwall.

Back-to-back wins had reignited the Foxes’ promotion bid and lifted them back to the top of the Championship.

But they slipped up in south London as the Lions, in need of the points for different reasons, battled to a first win in five matches to go four points clear of the relegation zone.

In a huge match at both ends of the table, Leicester’s defeat will have been welcomed by Ipswich and Leeds as the three-horse race for automatic promotion enters the final straight.

Millwall had a chance to open the scoring in the first minute, George Honeyman floating in a free-kick which Longman headed too close to Foxes goalkeeper Mads Hermansen.

Leicester quickly settled, though, and Stephy Mavididi – the late matchwinner against Birmingham on Saturday – should have done better when he was sent through by Yunus Akgun but his touch was too heavy.

Ricardo Pereira’s clever flick then found Kiernan Dewsbury-Hall, who slipped in Jamie Vardy.

But the 37-year-old former England striker was losing his balance as he got his shot away and Matija Sarkic made a comfortable save.

Dewsbury-Hall, playing as a number 10, took aim from 20 yards but his effort was deflected wide.

Millwall, happy to sit back and let Leicester have the ball, almost snatched the lead on the break before half-time.

Ryan Leonard whipped in a cross from the right and captain Jake Hooper got a firm head on the ball, but it was pushed away by Hermansen.

The goal arrived on the hour and, for Millwall fans at least, it was well worth the wait.

Wout Faes lost the ball in midfield and Billy Mitchell sent Longman scampering away down the left.

The on-loan Hull winger cut inside Harry Winks before curling a spectacular 25-yard effort past Hermansen and in off the underside of the crossbar.

Millwall almost doubled their lead when Michael Obafemi bulldozed his way into a shooting position but Hermansen got down well to save.

Leicester pushed for an equaliser and Pereira got in behind only to see his angled drive blocked by the legs of Sarkic.

They came agonisngly close in stoppage time but were denied by a goal-line clearance from Mitchell to keep out substitute Kelechi Iheanacho’s header.
