AUCKLAND, New Zealand — The Rugby World Cup is down to eight teams, with no surprises among the quarterfinalists and the stage set for a Northern Hemisphere vs. Southern Hemisphere final.

Defending champion South Africa will face Australia at Wellington on Sunday night. The meeting, between the only two-time World Cup winners, hadn't been expected until Ireland beat the Wallabies on Sept. 17.

Ireland plays Wales in Wellington on Saturday. England and France meet later that night in Auckland, on the eve of the Southern Hemisphere double-header involving top-ranked New Zealand against 2007 semifinalist Argentina and No. 2-ranked Australia against No. 3 South Africa.
