All Blacks and Blues prop Ofa Tuungafasi faces a spell on the sidelines and will miss the July tests against Tonga and Fiji.
Tuungafasi missed out on the Blues squad to face the Highlanders in Saturday's Super Rugby Transtasman final, with coach Leon MacDonald revealing the 29-year-old will have to undergo minor surgery to repair a knee issue.
"His knee is causing more trouble than what we had hoped and his finger is a bit of a mess as well so he's a bit battered at the moment," MacDonald said. "He's having a little tidy up to clear his knee up so that's going to keep him on the sidelines for a few more weeks."
An All Blacks update later confirmed that Tuungafasi will be ruled out of the two upcoming tests next month, but he is hoped to be available for selection for the Bledisloe Cup series against Australia in August.
The All Blacks squad for the July series will be named on Monday night.
