The All Blacks flanker Steven Luatua is in doubt for the Rugby Championship with a shoulder injury.
Luatua suffered the injury during the Blues' 34-13 loss to the Cheetahs in Bloemfontein that ended their playoff hopes.
The Blues coach Sir John Kirwan says Luatua could be out for up to six weeks, but it's hoped he'll be able to play within three or four.
The All Blacks' Rugby Championship campaign begins against Australia on August 17.
