Akira Ioane has been ruled out of the Blues' pre-season match against the Chiefs at Pukekohe on Friday due to a hamstring strain.
Ioane's brother, Rieko, and Ben Lam will play after their return from New Zealand sevens duties, but strike weapon Ioane will have the weekend off, although assistant coach Paul Feeney expects the big loose forward to be available for the team's first competition match against the Highlanders at Eden Park.
The trio have arrived back at the Blues after two triumphant sevens tournaments in Wellington and Sydney, with all three playing big parts.
Rieko, 18, has yet to play a Super Rugby match, and will spend time at centre and wing against the Chiefs, with Lam due to play on the wing.
Skipper Jerome Kaino said the trio had returned "seamlessly".
