Sitiveni Sivivatu's French club shuffle is off to a disastrous start with the former All Blacks wing facing up to four months on the sidelines with injury.
After three years with Clermont Auvergne, Sivivatu moved to Castres in the off-season, but he injured a shoulder in Castres' final pre-season game with Brive.
Specialist advice has confirmed he now needs surgery, meaning a lengthy spell of inactivity.
Castres, finalists for the last two seasons, open their Top 14 campaign against Stade Francais this weekend.
In other European rugby developments involving New Zealanders, former Auckland coach Wayne Pivac has been officially appointed as Llanelli coach.
Pivac moved to the Welsh club in July to be assistant to Simon Easterby. But Easterby's subsequent elevation to the Irish national team's set-up as Joe Schmidt's forwards coach, saw the Scarlets left in limbo ahead of the new season.
Suddenly Pivac, who has also handled Northland, North Harbour and Fiji but never been able to nail a Super Rugby appointment, has landed a glamour European head coaching role.
"Joining the Scarlets was an exciting challenge for me," Pivac said in a statement as Llanelli confirmed his appointment.
"I am honoured that the Scarlets have the faith and belief in me to take the squad forward and build on the good work and solid foundations that Simon and his team have put in place.
"The supporters here are probably no different to back in New Zealand. They're very passionate and love their rugby and really want the team to do well. I'm looking forward to hopefully giving them something to cheer about this season."
