It's half an hour to go before kick-off at Twickenham – where England will be determined to ensure Wales beating New Zealand is the only seismic upset of the day.
Rob Kitson has set the scene on what's at stake for England's players today – have a read.
For the first time since 1953, Wales have beaten the All Blacks! What an astonishing result. Many of the Wales players are in tears in Cardiff.
Here's our snap report, which will be added to soon.
We're a minute away from full time – still Wales 35-28 New Zealand! Apparently the Principality Stadium isn't full, but you'd never guess from the raucous support the fans are giving their team for this titanic effort. Can these Wales players make themselves heroes?
France edged South Africa 21-19 in a nail-biting match last night. Earlier today, Argentina held on to win 19-14 in Italy.
Right now: Wales are defending heroically/desperately in Cardiff. Eight minutes to go and they still lead 35-28 against New Zealand. Just about.
An electrifying Nations Championship game is taking place in Cardiff right now: Wales are winning 35-28 against the All Blacks with about 15 minutes left!
The hosts started like a train, scoring two tries in the first five minutes. New Zealand have kept reeling them in – but Wales keep on slugging back.
A reminder: Wales haven't beaten the All Blacks since 1953.

Screen tests for the new James Bond aren't the only major auditions taking place in England this autumn. With Steve Borthwick's claiming that "probably 26 to 28" places in his 33-man World Cup squad are decided, any players on the fringes will be highly motivated to impress. Which adds to the intrigue around this Nations Championship clash with Japan, for which Borthwick has made 10 changes from the XV that stuck 45 points on Australia last weekend.
Admittedly, some of those switches are down to injury woes – alas, Manny Feyi-Waboso! – but mainly it's England's head coach testing his depth/resting first-choice options for the All Blacks next weekend. That means a second England start for Henry Pollock (at No 8) while the exciting Max Ojomoh is at inside centre. Reliable George Ford gets the nod at fly-half.
As for Eddie Jones's Brave Blossoms: he'll be telling his charges that all these changes smack of England taking Japan lightly. (That's when Jones isn't telling England they struggle against "unorthodox" rugby.) Japan are coming off a respectable 28-21 defeat in Wales and Jones has said he is "looking forward to going to Twickenham with this young Japanese team that's going to play the house down".
Bold talk, even if the odds are firmly against Japan scoring a first ever win over England. Indeed, Borthwick's much-changed XV – full of players champing at the bit to prove their worth – may be an even tougher challenge for Japan than a first-choice lineup with half an eye on New Zealand.
