The Northern Tasmanian Social Soccer Association on Monday adopted a zero-tolerance approach to violence in light of the incident.

The association held a special meeting with representatives from its teams, including those involved on Saturday.

NTSSA secretary Tom Duff said the incident was a "completely unprecedented" event in their league.

"We got names of the players directly involved and have given them a three-week ban," Mr Duff said.

"It is a social league and people should feel safe during games."

He said allegations that the match umpire had been drinking were unable to be substantiated.

"The guy reffing at the time is well-known to everyone, we are confident it was a baseless allegation," Mr Duff said.

"The ref has played a game beforehand, he was not stumbling ... there is no way he would have been drinking, let alone drunk at all."

The social league does not offer any kind of insurance for its players, due to funding restrictions.

Mr Duff said that meant a zero-tolerance policy to drugs, alcohol and violence was imperative.

"We are stunned that this kind of incident occurred," he said.

"We have had very minimal problems before. People can get annoyed and frustrated but there has been no history of aggravation."
