All Whites midfielder Ryan Thomas is set spend a lengthy spell on the sidelines, after suffering an injury during training with Dutch club PSV Eindhoven.
The 23-year-old signed with the club earlier this month, after five years with PEC Zwolle.
Thomas injured his knee while trying to block a ball during training.
He will miss PSV Eindhoven's Champions League qualifier second leg against BATE Borisov next Thursday. His team won the first leg 3-2.
"During the inspection that you have to undergo for a transfer, I have been completely screened, everything looked good, when I blocked a ball on the training, I suffered this injury," Thomas told PSV's website.
"At first it did not seem serious, but we have had a scan made for safety and that did not look good. It seemed an innocent thing, but I'm out of it for a long time.
"It is not fun, but this also belongs to the life of a top athlete. In the coming days, we will look at what the best plan is and then I will get to work. "
Thomas has played 10 games for the New Zealand and has scored three goals since making his debut in 2014.
