Carter must undergo ankle op
All Blacks fly-half Dan Carter must undergo surgery to remove bone spurs from his right ankle.
Carter limped out of last month's Test victory over England at Twickenham and All Black medical staff have decided that he will need an operation to cure the problem.
Team doctor Tony Page has revealed the 31-year-old has also been suffering from "wear and tear" in his right Achilles tendon.
"Separately from that, Dan has some bone spurs in the same ankle which need to be removed so he will have an operation for that. This is similar to what he had done a few years ago," said Page.
Carter has begun a six-month break from rugby and will not rejoin his Crusaders Super Rugby side until July.
He will be rested for England's three-Test tour to New Zealand in June in an attempt to prevent further injury problems ahead of the 2015 World Cup.
