New Zealand rugby union international Aaron Cruden has been suspended for two matches after missing his team's flight to Argentina because of a late-night drinking session.

The All Blacks fly-half has apologised saying he is "embarrassed" by his lack of judgement, and says he has "never been more disappointed" in himself.

Cruden will miss the Rugby Championship games against Argentina and South Africa.

The 25-year-old scored the conversion which helped the All Blacks pip Ireland to victory during last November's International match.
