Leicester move five points clear at the top of the Premier League thanks to Shinji Okazaki's wonderful overhead kick. They looked a bit edgy at times during that, but Claudio Ranieri's side take another decisive step towards the title.
Newcastle United meanwhile remain second from bottom ahead of Sunday's crucial derby with Sunderland.
FULL TIME: Leicester City 1-0 Newcastle United
The ball breaks nicely in midfield for Mahrez and he can drive on with Vardy and Drinkwater breaking to either side to him. From about 5 yards out, he decides to take the shot on but his effort flies well wide.
Three minutes of time added on. Leicester are hanging on a bit, they have looked edgy throughout this half but if they can keep the ball in the corner as they are doing at the minute, they will be five points clear at the top again.
Drinkwater surges upfield brilliantly, relieving the pressure on his side and creating in attack in the process. He is eventually halted, but Mahrez gets it back and looks to open up and shoot like he did here against Chelsea, but his effort is blocked.
The ball now breaks foe De Jong in the box after a fine ball from Janmaat but he miss hits it and a tame effort is easily collected by the Leicester goalkeeper.
Vardy does well to shield the ball again and is clattered into for Shelvey for his trouble. It sees the free kick given to his side and Leicester can breathe for a moment, they are under pressure at the minute.
Townsend whips a wicked ball in from the right that loops clean over Schmeichel, leaving the Dane stranded. It breaks to Sissoko who lashes one on goal only to see it blocked by Huth? Was it with a hand? Newcastle scream it did, but play is waved on and Leicester clear.
Another big throw in from Fuchs causes havoc in the Newcastle box and Elliot is rather lucky as he collects at the second time of asking with Vardy lurking.
Just over 10 minutes of the contest remaining. It's been a pretty poor affair here, but Leicester won't mind too much if they get the three points needed to lift them five points clear again.
Here's a change for Leicester now with Albrighton to be replaced by Leonardo Ulloa.
Kante impeccably gets back again to usher out an overhit pass intended for Janmaat. The midfielder has enjoyed another tremendous game.
Another change for Newcastle, Siem de Jong replaces Perez.
This has all got a bit tame at the moment. Janmaat tries to pick out a teammate from the right but flings a cross straight into Schmeichel's arms.
Albrighton saves Leicester! Sissoko is fed the ball over the top down the inside left with Huth playing him on side and he has all the time to try and pick out the far corner. Instead, he slides it across to Townsend which is anticipated brilliantly by Albrighton who gets across in time to block. What a chance for Newcastle.
First change of the evening with Andros Townsend replaces Vurnon Anita.
Fuchs take it but the Newcastle wall stands strong and deflects clear.
Elliot just about pushes Alrbighton's cross away but Leicester keep the pressure on. Morgan, of all people, tries to dance his way into the box but has his effort blocked. Again, Newcastle can't clear properly and Vardy does well to shield the ball and win another free kick from Janmaat right on the edge of the box.
Mahrez takes on Sissoko and Colback down the left and beats them both, winning a free kick just a meter our so outside the box.
And Newcastle get us back underway for the second half.
Shinji Okazaki's wonderful overhead effort is the difference here at half-time. It's been a bit better from Newcastle, but still not good enough. Leicester haven't really had to get into the gear they have been operating at this season but they have shown no sign of nerves yet tonight and are heading towards another win as it stands.
HALF TIME: Leicester City 1-0 Newcastle United
Perez shows good feet to bring a pass under control and move it inside his marker before trying his luck with a curling effort, but it is easily saved by Schmeichel
Three minutes of this half remaining. The last 10 minutes have been really poor, lots of poor passes and questionable first touches. It is as quiet as the King Power Stadium has sounded all season.
Colback fails to control a ball, inviting Albrighton to run towards goal but he shows too much of it to the former Sunderland man, allowing him a reprieve.
