Pocock injury raises concussion specter in Super Rugby

WELLINGTON, New Zealand (AP) The danger of concussions and rugby's often muddled efforts to counter their threats were evident in the first round of the Super Rugby season and at the start of a World Cup year.

Wallabies star David Pocock lasted only five minutes of the ACT Brumbies' opening match against the Melbourne Rebels before being forced to leave the field with a concussion - his third in just over 12 months.

The Brumbies say they will take a cautious approach to bringing Pocock back, that he will miss Saturday's match against the Hamilton-based Chiefs and possibly the following match against the Wellington-based Hurricanes.
