Right, that's it from me.
For all the reaction to that big win for Sunderland head here.
All over! Big, big win for Sunderland.
David Moyes grits his teeth and punches the air.
What a chance! What a save!
There's a scramble in the Sunderland area as the ball pinballs around and eventually falls at Wes Morgan's feet. He shoots and Jordan Pickford bats it away. Crucial.
David Moyes rallies is his players from the edge of the technical area.
Win this and the Black Cats move up to 18th, one point from safety. What a big result it will be.
There's going to be SIX minutes of added time.
Into the final couple of minutes as Victor Anichebe picks up the ball with his back to goal, turns and powers forward, but his shot is weak, much to Leicester's relief.
Duncan Watmore is in pain after colliding with Christian Fuchs. He can't continue so on comes the stretcher. He's replaced by Javier Manquillo.
Hang on, this one isn't over yet!
Leicester pull a goal back as substitute Shinji Okazaki flicks in Demarai Gray's cross.
Can Sunderland hold their nerve?
Game, set and match.
Duncan Watmore's shot is blocked but the rebound falls to Jermain Defoe, who drives in for his eighth goal of the season.
Victor Anichebe has been everywhere for Sunderland, causing problems in attack and helping out in defence. He's put in a great shift.
All or nothing for Claudio Ranieri as he uses his final two substitutions, throwing on Ahmed Musa and Demarai Gray for Riyad Mahrez and Marc Albrighton. A bit of pace brought into the mix.
Yellow card for Seb Larsson as the referee catches him pulling on Riyad Mahrez's shirt.
Claudio Ranieri responds to that goal for Sunderland by making a change. On comes Shinji Okazaki for Islam Slimani.
Patrick van Aanholt falls to the ground after a challenge.. and he's booked. Referee thinks it was a dive.
Finally, the breakthrough!
It's unfortunate for Leicester as a driven corner hits Robert Huth and deflects into the back of the net.
Victor Anichebe shoots low from distance, but doesn't get anything behind it and Ron-Robert Zieler has so much time he could bob to the Sunderland canteen and make a brew before the ball reaches him.
Sunderland need to get back to what they were doing for the first 20 minutes of this game. They were excellent. Playing like a side at the bottom of the tabl now unfortunately.
Suddenly, though, Islam Slimani has a chance as a Jamie Vardy lets Marc Albrighton's cross run through to his strike partner, he shoots first time but the effort hits Papy Djilobodji right in front of goal. The Sunderland man didn't know much about it.
Riyad Mahrez has a pop from distance, forcing Jordan Pickford to punch his powerful strike clear.
Seb Larsson is making his first Premier League appearance of the season and is treated to Sunderland fans chanting his name.
It's Leicester who have started the second half better, although no chances yet.
Back under way with Sunderland making changes at half-time, Jan Kirchhoff is on for Steven Pienaar and Seb Larsson replacing Jason Denayer.
It's been a while since I covered a Premier League game and it's just my luck I've got the only one without a goal...
Jamie Vardy has been getting into some good positions so far in this game. If he can just improve his finishing then there is every chance he will end is scoring drought.
The whistle goes for half-time.
Sunderland started strongly but in the end, they will be glad to get into half time goalless as Leicester finished the better side.
Warm applause as they both get to their feet, although Steven Pienaar is still getting checked out. For now, Sunderland are playing with 10 men.
Two minutes of stoppage time but there's a break in play as Steven Pienaar and Marc Albrighton clash heads. Albrighton is eventually able to get up to his feet but Pienaar takes a little longer.
Oh, Jamie Vardy. The striker is getting in some good positions, but the execution of his shots are letting him down. He again gets away from his marker to meet a cross, spots Jordan Pickford off his line, but cushions his header onto the roof of the net.
Leicester could barely get the ball for the first 20 minutes but it is a much more even contest now. No real chances, though.
Ten minutes until half time and neither side is dominating.
There's a bit of a concern for Sunderland as Victor Anichebe drops to the floor clutching his ankle after Daniel Amartey stands on it.
He's made of strong stuff, though, and is soon back up and runs it off.
Sunderland went hard and went early but they've dropped the tempo now and Leicester are coming into the game. Jamie Vardy is unable to find a team-mate with an inviting ball across the box, before Marc Albrighton's cross is punched away by Jordan Pickford.
Wow. Wes Morgan. Wow.
The defender, under no pressure, attempts to launch a ball up field but succeeds only in curling it well out of play.
He tries to look for someone to blame, pointing to say someone should have run into the pace.
No Wes, that was just an awful ball there.
What a chance!
Christian Fuchs swings in a great cross from the left and Jamie Vardy gets away from the defence to get his head to it but compounds to glance it wide.
The Vardy of 2015-16 would have put that one away, no bother.
A chance for Leicester as Riyad Mahrez's shot deflects behind for a corner. Marc Albrighton swings the ball into the near post where Jamie Vardy rises to meet it, but heads wide.
Arsenal Ladies & England right-back on Final Score
Sunderland are having a lot of joy in behind the Leicester defence, and at the moment it only looks a matter of time...
Jermain Defoe's form this season has been red hot. He's got seven goals in 14 games and you'd expect him to find the target when he's picked out by a Victor Anichebe cross, but he misses his kick completely and Leicester escape.
Jordan Pickford fluffs his attempt to catch a weak ball into the box, putting his defence under pressure but fortunately they bail out the Sunderland keeper.
The Foxes are aiming to hit Sunderland on the counter through Jamie Vardy at the moment.
One of Leicester's main problems this season has been Jamie Vardy and Riyad Mahrez's inability to link up like they did last season but there's a flash of the old them as Mahrez gets behind the Sunderland defence and squares the ball for Vardy, but Lamine Kone just gets ahead of him.
Sunderland are clearly eager to maintain their recent form by getting an early goal and are playing very advanced in these opening exchanges. Leicester are yet to put together any sort of attack.
Now Patrick van Aanholt and Victor Anichebe exchange passes, allowing the former to race into the area. He skips past a couple of desperate lunges by Leicester players but eventually runs into one player too many.
