Dan Carter to miss two tests against Wallabies

New Zealand fly-half Dan Carter will miss at least the first two matches of the Rugby Championship against Australia after injuring his leg in last weekend's Super Rugby final.

Carter, the all-time leading points scorer in test rugby, was recalled to the All Blacks squad last week after sitting out the June internationals against England as part of a six-month sabbatical.

Playing for the Canterbury Crusaders in Saturday's loss to the New South Wales Waratahs at Sydney's Olympic Stadium, however, the 32-year-old left the pitch after half an hour.

"Dan Carter took a knock to his lower leg and a scan has revealed a small crack in his upper fibula," the Crusaders said in a statement.

"The size of the crack meant it was not originally picked up by an X-ray and required a scan to locate it. The injury will require just rest to heal and it is hoped that his recovery will take approximately four weeks."

Aaron Cruden, who started all three tests in the series sweep of England in June, is almost certain to deputise for Carter again when New Zealand take on Australia in Sydney on August 16 looking for a record 18th successive win.
