Highlights & reports of all three matches on the BBC Sport website
Italy 24-12 Scotland
And Italy are going for another here.
They're using the blind side well to suck in the Scottish defence. Dean Budd offloads to Leonardo Ghiraldini and they have numbers here on the left.
Sergio Parisse just needs to drive towards the line but his pass goes awry. The Italian captain is claiming a deliberate knock-on here.

Jane: Italy cutting up Scotland like a freshly-made haggis!
Major Tom: Supporting Scotland must be tough. From the heady heights of completely outplaying England to supremely underperforming against Italy.
Ewan Clark: Typical Scotland play well against England in their final but be rubbish the rest of the time.

Ryan Wilson misses the first tackle. Greig Laidlaw misses it in behind and then the execution once they're through is excellent.
Scotland didn't capitalise on the Italy try being chalked off and Italy have punished them. A brilliant finish from Jake Polledri and Tommy Allan. You can't take anything away from them.
Tommaso Allan, con Allan
What about that. Tommaso Allan with his second try of the half. Italy running riot.
Jake Polledri has been monstrous for Italy this afternoon, he shoves Ryan Wilson off as he charges down the middle and offloads to fly-half Allan.
Allan knocks over yet another kick and Italy have a 12-point lead again.

It is a knock-on and they've got away with it - a huge let-off for Scotland.
Italy 17-12 Scotland
The try is chalked off. Sebastian Negri's score will not count, the TMO spotted a knock-on.
Sergio Parisse's pass was poor and the captain has his hands on his head.
Oh hang on...
Marius Jonker the TMO is looking for a knock-on in the build-up.
Sebastian Negri
Power, acceleration, and Sebastian Negri starts the half with a bang.

Zander Fagerson is on for the Scots at half-time in place of WP Nel. No information yet on whether that is a tactical or enforced changed.
Meanwhile on the pitch, Italy are in their stride early in the second half and haring towards the line...
Italy 17-12 Scotland
Scotland were a little late taking the field for the second half, let's hope they'll be slightly sharper with ball in hand.
They need to up the ante and the tempo if they're to finish on a high in Rome.
Finn Russell gets us back under way.

Temperature update from Twickenham concourses: it’s so cold that taking out your phone to post a temperature update leads instantly to frozen typing flkiungherrs.
HT: Italy 17-12 Scotland
While Scotland battle the mild temperatures and a rather hot Italian outfit in Rome, things are a wee bit colder in England.

No, I lied. Hollie is my winner.
Just look at those eyes, and the pose. I've gone.

As are this quartet outside Twickenham.
In case you needed reminding, Ireland are going for the Grand Slam in just over an hour. Only England stand in their way.

Italy are shading possession and territory.
But it is nip and tuck over ever other stat. Scotland conceding seven turnovers is none too clever.

It was a really grim half of rugby for Scotland and they were fortunate to escape with that scoreline.
They've been doing a lot of defending in that first half - Fraser Brown alone has had to make 14 tackles. Physically, Italy are well on top at the moment and they have been very sharp so far. Scotland have made so many errors.
England v Ireland (14:45 GMT)
It's St Patrick's Day, and these Ireland fans have brought out their best garb for the occasion.
