Ireland 47-5 Samoa
Ireland are through to the World Cup quarter-finals after sealing a 47-5 win over Samoa.
The bonus-point victory secures a safe passage to the last eight no matter what happens in Japan and Scotland’s typhoon-threatened encounter on Sunday.
Two tries from Johnny Sexton and scores for Rory Best, Tadhg Furlong, Jordan Larmour, CJ Stander and Andrew Conway helped ease the Irish to victory in Fukuoka.
It leaves Joe Schmidt’s side top of Group A and on course for a clash with either New Zealand or South Africa.
Bundee Aki's red card for a high tackle on UJ Seuteni marred the victory, however, and now the centre born in New Zealand to Samoan parents will face a suspension.
The Connacht star had badly wanted to impress against his fatherland, but could now be banned for the remainder of the World Cup.
Speaking after the match, Ireland captain Rory Best said he has been delighted with his side's reaction to their shock loss against Japan.
"I think after the Japan game (the 19-12 defeat in their second group match)we knew 10 points would get us through and we've got that in the last two games," he said.
"The boys rolled up their sleeves.
"We know how good Samoa are and we knew they would come with no pressure on their shoulders and would come at us both in attack and defence.
"We stood up and at times we had to roll our sleeves up and it maybe wasn't that pretty, but I think we were very effective."
Ireland will not know their quarter-final opponents until the resolution of Sunday's match between the Brave Blossoms and the Scots.
World Rugby will rule on Sunday morning whether that match can beat Typhoon Hagibis and be staged as planned.
A cancellation would see the game ruled a scoreless draw and both teams awarded two points, with Scotland eliminated and Japan topping the pool.
Ireland would then face New Zealand on Saturday, 19 October with Japan taking on the Springboks the following day.
