The prospect of Hurricanes lock and one test All Black James Broadhurst returning to the playing field next year remains in doubt as he continues his battle to recover from concussion.
Broadhurst hasn't played since suffering two knocks to his head during a match for Taranaki in August 2015.
He didn't play for the Hurricanes during this year's successful Super rugby season this year as he continues to recover from concussion.
Broadhurst says he's still experiencing headaches during physical exercise.
"It has been difficult being unable to play the game I love for the past 15 months, but dealing with concussion is not something you can rush and in the end my long term health is the primary focus," he said in statement.
"I will be continuing a graduated return to exercise away from the team environment because, although I have made progress over the past year I do still experience headaches when my heart rate is elevated.
"On the advice of my medical advisers I won't consider a return to full training until I'm completely symptom free for the required period of time."
Broadhurst's sole test for the All Blacks was against South Africa in July 2015.
