North Melbourne ruck prospect Majak Daw has been suspended indefinitely by the club for "missing rehabilitation sessions and acting contrary to the club's culture and professional expectations."

Daw, 20, will be restricted to training with North's VFL affiliate Werribee. The athletic rookie is the first Sudanese-born player to make it on to an AFL list. He is yet to play a game for North Melbourne, but excited fans with several displays of skill and dash last season. He was re-signed for two years in October 2011.

A recent knee injury had set back his chances of pushing for a senior match early this season.

North Melbourne chief executive Eugene Arocca and chief of football Donald McDonald addressed the matter at a press conference at the Kensington boxing gym, but lived up to a statement released by the club stating that the club "will be limited in what they can say about the matter."
