The Kiwis defeated Tonga in front of 38,000 passionate fans at Eden Park, but there's one detail that caused some alarm.

Tongan second rower Eli Katoa took a shoulder to the head during warm-ups, and then took two additional head knocks  before being replaced in the 51st minute.

He displayed seizure activity on the bench before being rushed to Auckland hospital where he underwent brain surgery.

Former Warriors captain and former Kiwi Tohu Harris joined D'Arcy to voice his concerns.
