North Melb won't punish Archer for assault

North Melbourne won't punish former star and board member Glenn Archer for assaulting a runner at his son's junior footy match, and the AFL won't intervene.

The former Kangaroos star was on Friday fined $2000 for punching the volunteer official and was also ordered to cover the $955 replacement cost of the victim's glasses, broken during the June 25 clash.

Archer, 44, is revered as one of the toughest players to have donned an AFL jumper but the assault was slammed by a magistrate as "abhorrent" and a bad example for kids.

"It is an abhorrent thing to do," Heidelberg magistrate Cathy Lamble said as she convicted Archer.

"It sets such a bad example for children playing sport and a bad example to other parents."

Archer was watching his son Jackson play in the under-15s for Park Orchards at Heidelberg when he ran onto the ground to break up a scuffle between two players.

As players left the ground at half time, Archer clashed with opposition runner Jamie Chilcot, punching him to the side of the face.

North Melbourne acknowledged that Archer was apologetic and said they would take no further action.

"Glenn is able to continue in his role as a director," it said in a statement.

AFL chief executive Gillon McLachlan said the league will allow North Melbourne to deal with the matter internally.
