The All Black and Waikato midfielder Richard Kahui has had surgery on his injured right shoulder ruling him out of rugby for the remainder of the year.
Kahui re-injured his shoulder playing for Waikato against North Harbour earlier this month.
He had been out of rugby since suffering a small fracture of his right shoulder socket in the All Blacks' opening Tri Nations Test against South Africa in July.
All Blacks Doctor Deb Robinson said Kahui underwent an arthroscopy in Auckland late Wednesday which confirmed surgery was required.
She says the arthroscopic procedure had confirmed that the fracture was healing well, but Kahui had suffered a partial tear to his rotator cuff as well as minor cartilage damage, so had further surgery to repair those injuries.
Kahui will not be available for the All Blacks' end of year tour.
