Concussions are back in the spotlight and this time it is focused on Sonny Bill Williams.
After taking a heavy knock to the head last Saturday, Williams became disorientated and was seen stumbling about during his team’s opening match of the Rugby Championship against Australia.
SANZAAR is however looking into the matter, questioning whether medical officials should have conducted concussion tests on Williams.
According to sport24, the All Blacks centre was not checked out by the team's medical staff or the independent doctor employed to assess head injuries.
If anything detrimental comes of this incident, it could have repercussions for the All Black medical staff.
As cited by Rugby365, All Blacks coach Steve Hansen played down the incident, telling reporters: "I think everyone missed it to be fair, otherwise the HIA (Head Injury Assessment) doc would have taken him off.
"Our doc certainly would have taken him off."
All Black assistant coach Ian Foster added: "Sonny took a knock in the weekend, but he was symptom-free.
"The doc has done what he always does when there is a suspicion of something. He was held back a little bit [at training] so we could make sure he was absolutely clear, but the signs are really positive."
