Jerome Kaino has a minor hamstring injury that has ruled him out of the All Blacks World Cup pool match against Namibia.
Kaino, who was replaced after 65 minutes in the All Blacks 26-16 win over Argentina at Wembley Stadium, is likely to have been on the reserves bench at London's Olympic Stadium on Friday morning NZT, and could have played if it was an important match, coach Steve Hansen said.
Hansen's priority for the game - an almost guaranteed five points for the defending champion All Blacks given the gulf between the No1 side in the world and the 20th-ranked Namibians, most of whom are amateur players - is for all 23 men to come through the exercise unaffected by injury.

Only three players who started against the Pumas have retained their places - lock Sam Whitelock and wings Julian Savea and Nehe Milner-Skudder. Given the All Blacks have only three locks here, an injury to Whitelock or second-row partner Luke Romano would be a serious problem, as would any issue regarding Savea, the bullocking left wing who is poised to play an important role for his team in the knockout stages.
