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

North announced on Wednesday that Daw would train with VFL affiliate Werribee until further notice but would continue his rehabilitation from minor knee surgery under the supervision of club director of medical services Steve Saunders.

At a press conference at the Kensingston Boxing Gym, North chief executive Eugene Arocca and chief of football Donald McDonald refused to divulge specific details of Daw's indiscretions.

"He's breached rehabilitation protocols and internal codes and as a result of those breaches - which we're not going to go into for a very good reason, I would have thought - he's accepted the penalty and as a result of that he has to work his way back in (to the club)," Arocca said.

"We've got to respect Majak. He's a young man under a lot of pressure. Therefore, from that point of view to go into the specific reasons behind this would be unfair to him."

Arocca and McDonald did not detail what conditions North's new leadership group (new skipper Andrew Swallow, vice-captains Jack Ziebell and Drew Petrie, Brent Harvey and Daniel Wells) had put on Daw returning to Aegis Park.

"He just has to satisfy the leadership group that he's on the right track and he understands where they're coming from," McDonald said.

As the first Sudanese player to be listed by an AFL club, Daw, who turns 21 next month, has received an extraordinary amount of media attention for a rookie yet to play an AFL game.

However, McDonald said inexperience rather than over-exposure was to blame for Daw's suspension.

Arocca said Daw had accepted his suspension and understood the reasons behind it.

McDonald said North was disappointed in Daw's behaviour but reiterated the club would do all it could to help him return from his suspension.

"He's a North Melbourne boy and we'll support him 100 per cent", McDonald said.

McDonald said Daw's lack of commitment to his rehabilitation was not expected to delay his return to the playing field with Werribee.

Daw has spent the past two seasons on North's rookie list and was expected to push for senior selection early in 2012 until he suffered a recent knee injury. He re-signed with the Kangaroos for the next two seasons last October.

Daw's suspension not only dented his hopes of elevation to North's senior list it also overshadowed the club's announcement it had passed $500,000 in its Box On campaign to eradicate its $5 million debt.

Launched last December, Arocca said the Box On campaign had reached this milestone without holding any fundraising functions involving wealthy supporters.

Minutes earlier, North legend Glenn Archer had put his body on the line to support the campaign, sparring two rounds with Australia's International Boxing Federation middleweight champion Daniel Geale.

Despite pre-bout nerves - on climbing into ring, Archer said: "Where's the white towel?" - Archer held his own against Geale, even if both admitted afterwards the champ had taken it easy on the challenger.
