A Kelston Boys' High School parent who punched softball great Eddie Kohlhase on the sidelines of a rugby match will miss seeing his son play this season.
The parent, whom Kelston principal Brian Evans did not want to identify, hit Kohlhase from behind during an under-15 game at a Kelstonground.
Kohlhase's son plays for St Peter's College.
The Herald on Sunday reported the incident last week, when a linesman couldn't tell whether the ball had gone dead.
Kohlhase stepped in and told the referee it had gone out.
Evans said the ban was for at least the next year but would be reviewed.
He said Kohlhase had made it clear that he did not want the police involved, and the school accepted that. "We would have supported [a police complaint] if that was what he wanted."
St Peter's principal Kieran Fouhy said he trusted that Kelston had dealt with the incident appropriately. "They are a good school, they will do the right thing."
