Horie's got five more minutes in the sin-bin by the way.
Back to the action and Samoa clear out with a booming box kick.

That is a good judgement. It was dangerous, but there were mitigating circumstances. It is the right outcome and the match will only benefit from it.

The officials have said the "degree of danger was relatively low" so that's spared Horie.
And almost straight away Samoa are back to 15 as Jonathan Taumateine returns after his time in the bin.

We go again!
And I can tell you Shota Horie's tackle will remain a yellow-card offence. It was a clumsy challenge and nothing more.

The guys on BBC Radio 5 Sports Extra are discussing our ongoing bunker review.
Will Shota Horie be shown a red?

A victory for Japan would not only boost their own quarter-final hopes, it would also see England qualify for the knockouts.
Remember, anything but a Samoa win sees Steve Borthwick's side advance tonight.

Japanese yellow card. Should not be upgraded to a red as he just stood his ground and the Samoan player ran into him, so no need for mitigation.

Over on the Rugby Union Daily podcast Matt Dawson is joined by World Cup winning captain Martin Johnson, talking about England's 2003 route to winning the title.
"It is like falling off a cliff when you get knocked out, ultimately if you don’t win it ends in tears." Johnson, says.
"To get knocked out in the quarter-final, it is like the minimum expected of an England team."

A fascinating first half comes to an end.
Now then, what will happen to Shota Horie?

Excellent try, Samoa secured the ball and started to move forward.
Japan did look like they stopped the maul, but then Samoa came with another gear.
Really exciting game, finely poised.
Seilala Lam
A line-out to a driving maul, and Samoa get a try back as Seilala Lam goes over!
It's a well-worked try that sees Seilala Lam sneak over and Samoa wrestle their way back into this match.
Christian Leali'ifano misses the conversion attempt to keep it a two-score game.

How significant is the yellow card going to be, this gives Samoa a great chance.

Samoa kick to the corner. It's 14 v 14 now.

More drama! Japan forward Shota Horie is upright while making a tackle and there's head-to-head contact.
He's shown a yellow and goes to the bunker for a review.

Samoa have got to survive these next 10 minutes and they start off well, getting into a good position before Ben Lam is, possibly, obstructed off the ball.
The referee waves play on. A few boos ring out.

It gets worse for Samoa as Jonathan Taumateine is shown a yellow for a cynical shoulder barge off the ball in the build-up to that try.

Image source, Getty ImagesThat is the best piece of play we have seen in the whole match, Japan suddenly had an overlap. Rather than panic they just went through the phases and it was a brilliant try.
A big blow struck by the Brave Blossoms.
Michael Leitch (con Rikiya Matsuda)
Samoa can't keep up. They scramble to stop Lomano Lemeki down the right, so Japan shift the ball quickly out to the left, where Michael Leitch is handed the ball on the touchline and finishes in the corner.
Rikiya Matsuda then makes a tricky conversion.

Finally, some free-flowing rugby!
Japan are playing some proper lovely stuff now as Lomano Lemeki drives them forward.
