McCaw out of action against Hurricanes

Wellington - All Blacks captain Richie McCaw has been ruled out of the Crusaders' crunch Super Rugby match against Hurricanes after suffering a head-knock.

The 34-year-old flank was briefly knocked unconscious after being hit by a knee to the temple during last week's match against the Auckland Blues.

After McCaw came to training still suffering a mild headache on Monday, the team decided not to risk him, coach Todd Blackadder said.
