The pain is over. Nine-man Newcastle lost their eighth game in a row. Leicester have won four out of five to close the gap on the Magpies to a point.
Can it get any worse for Newcastle? Of course it can as Daryl Janmaat is shown a second yellow card for fouling Jamie Vardy - they will end this game with nine men.
And they will be without two of their first-choice defenders for the next game.
Siem de Jong has a shot for Newcastle but tipped around the post by Kasper Schmeichel.
Jamie Vardy comes back on after discussions with boss Nigel Pearson. His knock must not have been too bad.
Corner comes to nothing.
Jamie Vardy is limping off the field. Leicester have no substitutions left to make but if he's injured they surely won't risk him for the final few minutes.
Corner to Leicester.
This game is just drifting towards its inevitable conclusion here. Both managers would probably be happy to hear the final whistle.
Anthony Wood: From top to bottom, Newcastle United is a club in disarray. Heart and soul of the football club slowly withering away.
Anthony Shaw: Newcastle are in meltdown! Might do them some good to get relegated actually so they can rebuild. Dreadful!
Newcastle defender Paul Dummett, returning from injury today, was booked earlier and ran the risk of letting his team go down to nine men when he held onto Jamie Vardy.
BBC Radio 5 live's Stuart Pearce at King Power Stadium
"Leicester are a team transformed, they are playing with confidence, poise and panache. There is a lovely feel good factor around the stadium. It was the perfect time for them to play Newcastle."
No hat-trick for Leonardo Ulloa as the striker comes off for Andrej Kramaric.
By this stage I could come on and Leicester would still win.
BBC Radio 5 live's Stuart Pearce at King Power Stadium
"Newcastle look a very beaten and downcast side. Two instances in the game sum them up, the first is Mike Williamson's ridiculous second challenge that got him sent off.
"The second is halfway through the second half where Fabricio Coloccini got a knock in his own penalty area and stayed down holding his leg but gets up when the ball goes out of play. Your team are defending for your life, you can't stay down injured."
Dean Hammond's first touch of the ball since January is to blaze a shot well over the crossbar.
Leicester make a change as veteran midfielder Esteban Cambiasso comes off to a great reception and is replaced by the slightly less celebrated Dean Hammond.
Newcastle make a switch, Ayoze Perez is replaced by England Under-18 international Adam Armstrong.
Free-kick to Newcastle as Wes Morgan fouls Ayoze Perez on the edge of the box... But Jack Colback's free-kick is straight at Leicester keeper Kasper Schmeichel.
Tom Lowe: Newcastle need to spend £50m in the summer, more like a £100m investment. That squad is horrific. It'll never happen.
David Ljunggren: I've watched Newcastle for 30 years and of all the lows I've seen, this must be the worst. Going down might help us rebuild.

Leicester City - who continue to have the best of the attacking play - make a change in defence as Ritchie De Laet comes on for Marcin Wasilewski.
Newcastle make a change, Vurnon Anita comes on for striker Emmanuel Riviere and goes into defence. It's hard to see any way the Magpies could come back into this.
Newcastle United are down to 10. Defender Mike Williamson absolutely clatters Jamie Vardy down by the side of the pitch near the cameras and advertising hoardings. A second yellow card - he's off.
I didn't see what happened initially as the camera we were watching from is the one Vardy was bashed into!
Leonardo Ulloa almost has his hat-trick but his header from Riyad Mahrez's cross is well saved by Tim Krul.
It looked like it was going to be a goal - in fact BBC World Service's John Bennett, who is sat near me, almost leapt out of his seat to celebrate 4-0!
