# Rugby: Ireland will replace South Africa in top spot in the world rankings if the Springboks should lose to Australia in their Rugby Championship Test in Perth today. A draw will also see the Irish leap-frogging the world champions. The Wallabies will improve from ninth to eighth place if they win. If the All Blacks should lose to Argentina again, they will slip to fourth in the rankings. New Zealand and Argentina kick off in Auckland just after nine, followed by the Boks and the Wallabies at 11.45.
