All Blacks: Damian McKenzie ruled out of Rugby World Cup with ACL injury

All Blacks utility back Damian McKenzie has been ruled out of the Rugby World Cup with an ACL injury.

The 23-year-old picked up the injury during the Chiefs' 33-19 Super Rugby win against the Blues on Saturday night.

The injury occurred early in the second half when attempting a tackle on first-five Otere Black.

Coach Steve Hansen confirmed the news at the All Blacks' foundation day in Wellington on Monday.

"He's done an ACL and looks to be out for eight to nine months which is a real shame for him," Hansen said.

"His World Cup opportunity's gone but he's still young enough to make probably the next two. It's just important he gets his knee right and takes the time to be able to come back and achieve the dreams that he wants to achieve."

"It's sad for him obviously. It creates another opportunity for someone else. We've got to expect injuries and there will be more than just him I'd say."

McKenzie was expected be one of the three first-fives selected for the World Cup, along with Beauden Barrett and Richie Mo'unga.
