And that's that from this live text.
And that Drinkwater effort is pretty much the last action of a belting second half at Selhurst Park.
A point for each edges them both closer towards safety. Both managers may also rue missed chances to win it and all-but guarantee survival.
A terrific game nonetheless.
Brilliant work from Jamie Vardy as his cross is poorly cleared by Patrick van Aanholt, straight to the feet of Danny Drinkwater.
Here's your chance to win it, Danny! But, no, the substitute fizzes his effort just wide, agonisingly close.
The Foxes still want this - the excellent Marc Albrighton now getting free down the right to fire in a cross that is just about cleared by Martin Kelly ahead of the incoming Jamie Vardy.
Ugh, ugly from Albrighton at the resulting corner as his delivery drifts out of play. Pretty much the first thing the Leicester winger has done wrong all afternoon.
Corner to Palace but nothing doing as Leicester clear.
Palace finally deal with a Christian Fuchs throw, though, and clear their lines.
Edging towards a draw at Selhurst Park.
It's substitute Demarai Gray to take but Palace hold firm to repel - Christian Fuchs to deliver another trademark long throw...
Jason Puncheon strides into the Leicester area, scrambling the visiting defence, who do well not to trip the tricky midfielder before Robert Huth stands tall to clear.
The Foxes go up the other end and win a corner...
Crystal Palace are the biggest winners in the survival race as it stands. The three most important words in football.
The Eagles are the only side in the bottom seven earning a point. And they want more against Leicester...
James McArthur is on for Wilfried Zaha.
A sign Big Sam is happy to settle for the point?
A third Palace appeal for handball in the area as Patrick van Aanholt gets in near the byeline on the left, squaring the ball for Robert Huth to slide in and just about prevent from going out for a corner.
Palace think it struck Huth's arm but looks like it rolled up the German's torso.
The hosts looking the more likely winners here.
Yohan Benalouane is off, with Ben Chilwell on as Leicester make their final change.
The deputy centre-back did well until he was over-powered by Christian Benteke for Palace's second.
Leicester were livid the goal stood and Mike Dean didn't give a foul on Benalouane. There was a bit of a nudge from Benteke but the Foxes defender didn't jump to contest the loose ball, somewhat harming his case.
Now Andros Townsend showing great pace again, squaring the ball again - this time Leicester deal with the first cross but it falls to Luka Milivojevic, who sees his effort well blocked by two diving Foxes defenders.
Cracking last 15 minutes in store at Selhurst Park.
Demarai Gray on, Riyad Mahrez off.
Drama at both ends still though - yet another Christian Fuchs long throw that Palace make a hash of clearing, this time flicked on by Leonardo Ulloa.
It appears to hit a Palace arm but Ulloa doesn't stop, flashing a volley just wide of the net.
Three points up for grabs here.
The Foxes are on the ropes here as Palace attack with pace and verve once more, setting up that man Christian Benteke on the left, but his low effort is well saved by Kasper Schmeichel and Robert Huth just about gets to the rebound first to hack it clear.

Christian Benteke is big, strong, powerful and shows desire. A great finish, as he powers forward and converts the chance.
A terrific fightback from Palace is capped when Andros Townsend gets free down the right once more and floats in a brilliant ball for Christian Benteke to attack at the back post.
There's plenty to do for the Belgium striker as he climbs above Yohan Benalouane to head home.
It looked a little ungainly but so effective from Palace.
The big Belgian bundles home.
Another appeal for handball from Palace players and fans behind the goal but again not clear what part of a Leicester body it struck as Christian Benteke proved a nuisance.
Patrick van Aanholt, just back from injury, is on to replace Jeffrey Schlupp.
Another corner for Leicester as they keep up the pressure - Riyad Mahrez's delivery is cleared by Christian Benteke though as Palace charge foward.
But the big Belgian tries to do it all on his own despite having Jason Puncheon and Wilfried Zaha in support.
Again it's a Christian Fuchs long throw causing panic in the Palace area as Joel Ward is forced to head just about over his own bar.
Danny Drinkwater enters the fray to replace Andy King.
Ouch! Andros Townsend is absolutely nailed by Andy King as he tries to break free down the left.
A free-kick in a decent position for the hosts... but Yohan Cabaye's delivery is poor and fails to beat the first man.
But don't rule out a third for Leicester either.
Riyad Mahrez is enjoying his football again, threading a fantastic ball down the right for Jamie Vardy to run onto and square across the area.
Joel Ward intercepts but nearly gets caught on the ball - resorting to belting it out for a throw as the Foxes keep up the pressure.
All Palace now and Wilfried Zaha at the heart of it all.
The winger pops up on the right first, blazing a drive just high and wide of the bar.
Moments later he's wreaking havoc down the left, his low cross cleared by Yohan Benalouane for a corner.
Now it's Leicester's turn to switch off at the back, just one minute 55 seconds after Vardy's goal.
Palace work the ball left in the area for Jeffrey Schlupp, who tries to make amends for letting Vardy beat him by shooting, only to see his effort blocked.
But it falls brilliantly for Yohan Cabaye to follow in and sweep the ball low under Kasper Schmeichel.
The Foxes guilty to not reacting but Cabaye does well to grab his second goal in as many games at Selhurst Park.
Oof. There's life left in this one.
Leicester break at pace following the Palace corner - it comes to Riyad Mahrez, who shows great vision to set Jamie Vardy free.
The England striker tries to streak clear of Jeffrey Schlupp but then checks back and turns inside, curling a terrific left-foot shot just far enough away from Wayne Hennessey's dive.
A thing of classic title-winning Leicester beauty.
What a beauty.
Big shout for a penalty from the home fans and players as Wilfried Zaha's clipped cross strikes some part of Marc Albrighton.
The Leicester winger says it hit his chest and is probably right. Palace corner.
Marc Albrighton shows he can do it with his right too and he flicks in a teasing cross towards Leonardo Ulloa but Martin Kelly does well to cut out the danger.
The Foxes have started the second half well.
Ex-England defender on Final Score
Leicester were terrible earlier in the season. They would lose games immediately before and after European matches. But clearly today the manager isn't resting anyone because he is prioritising the league - today is about survival.
Neat flick-on from Leonardo Ulloa to strike partner Jamie Vardy, who collects on the turn and is clipped but doesn't go down.
The ball finds itself back out to Riyad Mahrez, whose curling cross-cum-shot evades the incoming Leicester attackers and falls wide of the far post.
Plenty of early hustle and bustle from Marc Albrighton again down the left, but he over-hits his cross out for a goal-kick after beating Joel Ward.
And we're back under way..
Looking at some half-time stats, it's no surprise to see Marc Albrighton has covered the most ground of any Leicester player (5.94km) and also made more sprints (37) than anyone else on the pitch.
The Foxes winger has been everywhere, drifting inside when Leicester lose the ball to help cover his defence and springing down the left on the counter-attack.
An intriguing game so far - one total lapse of concentration from Palace and Leicester took the lead as Robert Huth headed in Christian Fuchs' long throw.
Other than that, Leicester haven't threatened much but look strong in defence.
Still enough to encourage Palace that there is a route back into this one though.
...but Mike Dean blows the whistle just after the free-kick is taken to signal an end to first-half proceedings after just one minute of added time.
