The Wellington Hurricanes have confirmed that All Blacks scrumhalf Cameron Roigard suffered a rupture to the patella tendon in his left knee last weekend and will be sidelined for at least six months.

The 23-year-old had a breakout season for the Hurricanes in Super Rugby Pacific last year and earned a spot in the New Zealand squad for the World Cup, where he impressed despite being used sparingly as the All Blacks reached the final.
