Chiefs halfback Tawera Kerr-Barlow's All Blacks ambitions have been hit by a broken hand which will rule him out of the game until after the June test window.
Kerr-Barlow suffered the injury during his team's 28-27 victory over the Hurricanes in Wellington last weekend when his fist made contact with Aaron Cruden's head during a tackle.
Cruden suffered a cut head during the incident but carried on, as did Kerr-Barlow, only for the fracture to be diagnosed recently.
Chiefs coach Dave Rennie confirmed the injury to media today.
It is the latest in a series of injuries for Kerr-Barlow, who has already missed several matches this season due to concussion.
Adding to Rennie's injury issues, wing James Lowe and midfielder Charlie Ngatai are again unavailable due to shoulder injuries.
