Concern is growing that Patrick Tuipulotu's groin injury could rule him out of the World Cup.
The Blues lock has been sidelined for several weeks by an injury that refuses to respond to treatment. It is understood that more information will be available early next week following scans.
Those investigations will determine what happens next. Options will include immediate surgery, which will involve a rehabilitation period of three months, a timeframe that will make things tight in terms of the World Cup, or an operation after the tournament.
Tuipulotu is understood to be extremely concerned about where the injury leaves him in the All Blacks selectors' plans.
The 22-year-old, who played seven tests during his breakthrough year in 2014, has risen to the top of New Zealand's second tier of locks behind Sam Whitelock and Brodie Retallick.
