The All Blacks are sailing on through the Rugby Championship but rivals Australia and South Africa continue to run into injury troubles. Matt Toomua's worrying head knock history could ground him for the rest of Championship as the Wallabies wisely protect him from long-term after-effects. The experienced centre will now miss the Tests against South Africa and Argentina next month and could be spelled from the two return Tests in October. Toomua's recent concussion against the All Blacks in Sydney was his fourth in The Rugby Championship in three seasons. South Africa face the struggling Wallabies on September 10 and world champions New Zealand a week later in Christchurch.
