Oh glorious!
Samoa run from deep. Maurie Fa'asavalu slips an off-load out of the side-door. Superb smuggling. It finds the hands of Reynold Lee-Lo. He motors upfield, but his own pass is a dud as he attempts to put his winger away and instead pops the ball straight to the pursuing Tommy Seymour.

Quote MessageI would love to have been a fly on the wall in the Scotland dressing room at half-time. The Scotland crowd are absolutely desperate to see their team go in front for the first time."

They go for the corner again. Cheers in St James' Park for the positive approach.
Groans though as Scotland get in front of each other off the line-out and Samoa get their own penalty.
Obstruction in midfield from Samoa centre George Pisi.
The penalty might have just been inside Greig Laidlaw's range, but instead Finn Russell punts down into the Samoa 22m.
One push-over try already today from the Scots, can they get another?
Dov Tate: As a Wales fan watching #SAMvSCO, external this has all the hallmarks of Nantes in 2007. Need to stop playing Samoa at their own game
Scotland 23-26 Samoa
Scotland are straight onto the front foot, Matt Scott doing well to retain possession on the Samoa 22m line through a shuddering hit from Jack Lam.
But they come off their feet at the breakdown and allow the Pacific Islanders to relieve the pressure with a nudge back up to halfway.
Image source, RexIt is worth flagging up that if Scotland score four tries and lose by seven points or less then Japan would have to secure a bonus-point win over the United States on Sunday to overtake them and seize a last-eight spot.
Let's see. Second half is locked, loaded and ready to go.

Paul Baldwin: My attempt at supporting Scotland has failed. Samoa are just too exciting so it has to be #ComeOnSamoa, external
Stephen Murray: If I wasn't a Scottish fan, best half of rugby so far this World Cup, two teams just wanting to play and score tries!
Adam Shaw: The Samoans are bossing the breakdown. Scotland won't have a platform to let the backs attack unless they sort it out.

"Not sure of it's the Welsh or Aussie fans, but somebody wants the Pacific Islanders to win today.
"Perhaps they prefer the prospect of today's winners here facing Japan in the quarter final, rather than the Scots."

Quote MessageScotland are a wee bit shell-shocked not quite expecting this sort of onslaught. Vern Cotter, I have absolutely no doubt, will have some strong words for his charges at half-time. It has all been Samoa, they are fully deserving of their lead."
Scotland 23-26 Samoa
Image source, BBC SportWhat a half of rugby.
Scotland need to get hold of this and snuff out Samoa's end-of-term high jinks.
Vern Cotter's side have been better in the second half of all their World Cup matches so far. They will need to be again.
Scotland 23-26 Samoa
Trusting a forward to look after the ball is like trusting a City trader to look after your pension. High risk.
Samoa spill forward and Jaco Peyper sends us all for a sit-down and a chance to breathe.
Image source, Rex FeaturesSamoa are finishing the half the stronger.
Final play of the half and they choose to run a penalty from within 15 metres of the Scotland line.
"Keep on your feet and look after the ball," barks scrum-half Kahn Fotuali'i as he sets the forwards rumbling.

Scotland need to start playing properly. Just cos Samoa are running everything from behind their 22, doesn't mean you have to

Tusi Pisi clumps the kick through the sticks to kick a penalty from roughly where he would have taken the conversion had the try stood.

Scotland 23-23 Samoa
No try, but we are going back to the first offence in the passage of play which was a Scotland offside...
Scrum-down? Or kick for sticks?

Sakaria Taulafo ploughs over from around the fringes. But there has been some skulduggery.
Tim Nanai-Williams dragged Greig Laidlaw away from his guard position at the base of the ruck to clear the way for his team-mate.
Surely that is not going to stand...
