Result: Ireland 47 Samoa 5.
Ireland booked their place in the World Cup quarter-finals with a seven-try win over Samoa in Fukuoka.
Ireland had to play over half the match with 14 men after Bundee Aki's 29th-minute dismissal, though tries by Rory Best, Tadhg Furlong and Johnny Sexton had already put them in control.
Ireland's opponents in the last eight will be determined by the outcome of the final Pool A fixture between Japan and Scotland on Sunday, which could still be cancelled with Typhoon Hagibis wreaking havoc in Yokohama.
If that game does not go ahead, both sides would be awarded two points and Japan would top the group ahead of Ireland, leaving Joe Schmidt's side to face three-time champions New Zealand.
If it does go ahead, a Scotland victory without Japan claiming two losing bonus points would see Ireland finish top, with South Africa their quarter-final opponents.
