NORTH Melbourne hopes the investigation into its handling of concussed player Lachlan Hansen will end soon after it provided the AFL with an explanation for its actions.
Interim Kangaroos chief executive Cameron Vale emailed AFL operations manager Adrian Anderson on Monday after the Roos were told to respond to a ''please explain'' issued by the league last week.
The Kangaroos have been under investigation over the manner in which they handled Hansen after he received a heavy knock against Essendon in round 20, and also for the way they have responded to AFL investigators Brett Clothier and Abraham Haddad in recent weeks.
The AFL has been unimpressed with the club's handling of the issue, although the Kangaroos have bristled at suggestions football manager Donald McDonald had influenced the testimony of key figures involved.
The Kangaroos are confident club doctor Andy McMahon will be cleared.
The investigation could be wrapped up within the week.
