Beauden Barrett

Both Barrett and Fifita suffered their concussions in last night's 26-13 win over France in Wellington.

Barrett's incident occurred in the 12th minute of the match when he collided in mid air with France fullback Ben Fall.

Fall was red carded for the incident because Barrett landed on his neck and head.

Coach Steve Hansen says both Barrett and Fifita will stay in Wellington tonight and will be monitored throughout the week.

Hansen said a decision will be made later in the week on whether they'll join the group in Dunedin ahead of Saturday's test.

The skilful fly-half joins All Blacks great Richie McCaw as the only player to have retained the award, while Barrett, McCaw and the great Dan Carter are the only three to have won the prize more than once.

Barrett enjoyed another stellar year in international rugby, helping New Zealand retain the Rugby Championship, while he was also a part of the side that drew a thrilling series with the British and Irish Lions 1-1.

Hurricanes coach Chris Boyd confirmed Barrett missed the Hurricanes' 34-20 win over the Bulls in Pretoria, because of headaches.

It means one of the All Blacks' key men for next month's Lions series will need to pass concussion protocols to be cleared to face the Force on Saturday night.

Flanker Ardie Savea is another, along with lock Mark Abbott, after both suffered concussion symptoms on Sunday and would appear unlikely to play against the Force.

The defending champions overcame a red card to the All Blacks first-five to beat the Waratahs 38-28 in their Super Rugby clash in Wellington.

The World Rugby player of the year scored a try, but was also judged to have deliberately knocked the ball down twice in the match.

He was sent off in the 60th minute after receiving his second yellow card for the same offence.

The Hurricanes coach Chris Boyd hopes the red card is all that Barrett will cop.
