Portugal Colonial - All Blacks captain Barrett out of South Africa tour, faces back surgery

Canterbury Crusaders coach Rob Penney told reporters in Christchurch that Barrett would have to go under the knife this week.

"He has tried every non-invasive trick you could do to get right and it just hasn't come off, so he'll be in the operating theatre by the end of the week," Penney said Wednesday.

Barrett had taken a sabbatical and had planned to return to rugby in April but has been frustrated by the injury.

"He's got his head around it now. It's a pretty special trip to South Africa that he's going to miss and some other bits and pieces," Penney said.

"Ultimately, he's just got to get himself right."

Barrett will miss home Nations Championship Tests against France, Italy and Ireland in July.

New Zealand will then depart without him for an eight-match tour of South Africa in August and September, including four Tests against the world champions Springboks -- dubbed "Rugby's Greatest Rivalry".

Crusaders are also without All Blacks wing Will Jordan, who has been ruled out of the remainder of the Super Rugby season with a calf injury.

Jordan should be fit to return for the July Tests.
