Blues and All Blacks lock Patrick Tuipulotu is set to miss the June test series against France due to a shoulder injury he suffered in last Friday's defeat to the Hurricanes.
Tuipulotu left the field in the 36-15 loss and is unlikely to return for the Blues until after the international break.
The 25-year-old played four tests for the All Blacks last season but is likely to be unavailable for the three-test series against France which begins on June 9 as well as the Blues next two games before the break.
Fellow Blues lock Josh Goodhue is also set to miss Saturday's clash against the Crusaders due to concussion, meaning the Blues are set to start a relatively inexperienced lock combination of Gerard Cowley-Tuioti, and Ben Nee-Nee.
Tuipulotu's injury is especially unfortunate due to his recent run of issues with his body and the fact he was beginning to come into the sort of form which saw him selected for the All Blacks last year.
