I'm going to call a halt now, but you can catch all the post-match reaction to Leicester's survival - and Sunderland's move towards safety - on ourmain live text commentary. Thanks for your company.
- Sunderland XI: Pantilimon; Jones, Coates, O’Shea, Van Aanholt; Larsson, Cattermole, Bridcutt; Defoe, Graham, Wickham
- Leicester XI: Schmeichel; Wasilewski, Huth, Morgan; Albrighton, King, Cambiasso, Schlupp; Mahrez; Ulloa, Vardy
Leicester keeper Kasper Schmeichel: "If you look at the squad we've assembled, we don't shy away from a fight. We got into a bad position but the attitude was spot on. We've worked really hard and got our rewarded.
"The manager is the best I've played for. He's kept going and believed in what we've built here. He's built a squad that reflect him as a person, because he doesn't shy away from a fight."
So here are the standings. Leicester's point moves them safe, and out of the bottom six. Sunderland still need another point to be sure.
Leicester captain Wes Morgan: "We knew we had to keep calm. A point is a great result. To get from where we were 18 months ago to where we are know, I'm delighted. A lot of people wrote us off a couple of months ago, and I feel we've proved a lot of people wrong."
The reaction from Sunderland's fans is a little more muted - until they hear Newcastle have lost 2-1 at QPR. Defeat, too, for fellow relegation rivals Hull, who lose 2-0 at Tottenham.
Leicester's players embrace each other at the final whistle; manager Nigel Pearson raises his arms in celebration, the fans chant 'We are staying up', the club's Thai owners smile in the directors' box.
It has been a magnificent effort from the Foxes. Seven points from safety with nine games to play, they have stayed up with a match to spare. Well done, Leicester.

"That will do for Leicester. There have been some special ones, but this has to go down as the greatest relegation escape the Premier League has ever known."
Well, that's one way to start a debate, Guy.
Leicester are running down the clock pretty comfortably here - and then, suddenly - a chance!
Sunderland keeper Costel Pantilimon surges from his line to try to deal with a through ball that he should leave to captain John O'Shea. The ball runs loose to Andrej Kramaric... but the Croatia international is wasteful, and the shot sails over.
BBC Match of the Day commentator at the Stadium of Light
"Nigel Pearson's side are almost there. The fans in the away section are singing: 'We are staying up.'"
Three minutes of stoppage time...
Leicester striker Jamie Vardy turns on the edge of the penalty area, and feeds Andrej Kramaric to his right. Could there be a winner here? No, the shot is deflected into Costel Pantilimon's hands.
But Sunderland can't work the ball forward to start an attack, and suddenly Jeffrey Schlupp is racing on to a through pass. This time, Pantilimon is quickly off his line to boot clear. A tense finale, this...
Steven Fletcher hasn't scored for Sunderland since November, but he almost puts that right. Adam Johnson, who has played well since coming on, crosses in from the right, and Fletcher glances just over.
Black Cats full-back Billy Jones has hobbled off, unable to continue, and Anthony Reveillere replaces him for the last five minutes.
It's going to end 0-0 this, isn't it?
It looked like being an exciting, open game in the opening few minutes. It's been gripping drama, but largely for its feistiness rather than its football.
Seb Larsson collects a booking for hacking down Marc Albrighton, but Esteban Cambiasso curls the free-kick way over the bar.
Back at the Stadium of Light, the tension is palpable. Sunderland have to defend a corner. Striker Danny Graham doing his bit for the team, is back defending to glance the ball away.
Oldham's push towards Premier League safety under manager Joe Royle in May 1993 was little short of sensational. Six points from safety with three games left, they had it all to do - and did it.
First they won at title-chasing Aston Villa, a result that handed the trophy to Manchester United, then they beat Liverpool before winning a nerve-shredding final-day classic 4-3 against Southampton - staying up on goal difference at Crystal Palace's expense.
Yes, the Latics were relegated 12 months later, and haven't been back to the top flight since, but this was a moment to remember.
Another change for Leicester. Top scorer Leo Ulloa, who has done his best in the face of some pretty sturdy treatment from John O'Shea, makes way from Andrej Kramaric.
Meanwhile, Sunderland win their millionth corner. The visitors' defence once again stands firm. They have been resolute today.
Sunderland substitute Adam Johnson cuts in from the right on to his left foot in search of a winner - and the shot towards the near post is good, but Leicester keeper Kasper Schmeichel pushes it behind for a corner. The visitors deal with the set piece, and edge closer to that precious point...
Meanwhile, Leicester manager Nigel Pearson has taken off attacking midfielder Riyad Mahrez and put on the more defensively-minded Danny Drinkwater. That suggests he'll be happy with a point. Might have to revise my prediction about this match not ending 0-0 now.
As things stand, a point will be good enough to see Leicester safe. Sunderland won't quite be there - they'll need one more point from their final two games to be certain. Those final two games are away to... Arsenal and Chelsea. Mind you, Hull - currently third from bottom - have to play Manchester United yet. Twists and turns to come...
Sensational developments at Loftus Road. Leroy Fer has put QPR in front against Newcastle.
Back at the Stadium of Light, Sunderland left-back Patrick van Aanholt surges forward from left-back and drills a shot that whizzes wide. There's an 'ooh' from the home fans, once they look up from searching their smartphones for scores elsewhere. Hello, if you're scanning this page.
And at White Hart Lane, better news still. Danny Rose has given Tottenham a 2-0 lead against Hull.
QPR may be down, but at least they're making a game of it against Newcastle, drawing level at Matty Phillips converts Charlie Austin's cross. A goal that makes life a little more nervy on Tyneside, to the delight of all on Wearside.
There's another roar around the Stadium of Light. Sunderland push forward, sensing their chance to get safety secure once and for all. But they can't make anything of a corner, and Riyad Mahrez surges away for Leicester on the break - only to lose his footing. End to end, this, but still not many clear chances. Meanwhile, at Loftus Road...
There has now been a goal at White Hart Lane, and it's great news for both Sunderland and Leicester. Relegation rivals Hull, who started the day in the bottom three, are trailing at Tottenham, with Nacer Chadli scoring.
Almost a quarter of a century ago, Sheffield United arrived in the top division - and got off to an horrendous start, failing to win any of their first 16 league games.
They finally recorded their first victory on 22 December 1990, beating Nottingham Forest 3-2. Led by such luminaries as future movie star Vinnie Jones and future Manchester City football administration officer Brian Marwood, United claimed 36 points from 19 games over the second half of the season and finished in a comfortable 13th place.
A roar goes up around the Stadium of Light. For a moment, I wondered if there might have been news of a goal in one of the other games affecting the relegation scrap. But no - it's as you were at half-time: Newcastle lead 1-0 at QPR, Hull are drawing 0-0 at Tottenham.
Leonardo Ulloa is having to scrap for every chance this afternoon, but he almost opens the scoring for Leicester with a cute back flick from Marc Albrighton's cross into the box - and Patrick van Aanholt knees the ball over his own bar for a corner.
Albrighton takes it - and Ulloa seems to be having his shirt tugged by John O'Shea, but gets nothing from referee Martin Atkinson as he heads wide at the near post.
We're back under way here. And I stand by my prediction that this game won't end 0-0.
I've been looking at some classic relegation escapes from the past this afternoon as Sunderland and Leicester look to complete a push towards safety.
With that in mind, I'd like to point you towards'West Brom's Great Escape', a show on BBC Radio 5 live at 22:00 BST this Monday.
It's a look back on West Brom's escape of 2005 when they amazingly avoided relegation on the final day of the season despite being bottom of the league. It includes interviews with former West Brom manager Bryan Robson, striker Rob Earnshaw and defender Paul Robinson.
Leicester enjoyed a good deal of possession in that first half, winning a lot of set pieces, but without creating too many clear chances.
Ben Pringle: Well done Lee Cattermole. Only you could equal the most yellow cards in a season after being out for two months.
Lee Cattermole then immediately pushes his luck by bringing down Riyad Mahrez near the halfway line. Referee Martin Atkinson settles for handing out a talking to this time.
The least surprising moment of the afternoon - a booking for Lee Cattermole. The Sunderland midfielder can't stop Marc Albrighton's progress down the right, and brings down the Leicester man - collecting his 14th yellow card of the season.
Cattermole has been booked more times than anyone else in the Premier League during 2014/15.
I still don't think it's going to end 0-0, this.
Robert Huth in the thick of things. First the Leicester centre-back goes in a little aggressively on Sunderland keeper Costel Pantilimon at a corner; then he concedes a free-kick right on the edge of his own penalty area by bringing down Danny Graham...
Seb Larsson plays the free-kick short to Connor Wickham, but Leicester's wall is out quickly from behind the vanishing spray to block.
