Rising heavyweight boxing star Joseph Parker has called for supporters to be kept further away from sports fields and courts to limit the danger of violence and abuse.
Parker, 21, signed up as a Herald on Sunday Sideline Champs ambassador this weekend, alongside the likes of All Black Richard Kahui, Silver Ferns captain Casey Kopua, Warrior Manu Vatuvei, World Cup football star Ivan Vicelich, and Breakers basketball skipper Mika Vukona.
Boxing has a reputation as a macho, testosterone-fuelled sport - but Parker said the worst behaviour he had seen was on the sideline of rugby and league matches at school or club level.
He recalled playing in a rugby game between Mangere East and Otahuhu, a few years ago, in which the whole team got into a fight with the opposition.
"Then there were family members jumping in and fighting, trying to protect their loved ones," he said.
