Video of the brawl shows a group of at least six men, one wearing a Tigers guernsey, throwing punches as dozens of shocked patrons watch.
Mr Ashton said while violent incidents at footy matches hadn’t increased, the severity of the violence had.
“On Friday night, for example, we had a couple of fights at the MCG that we’re dealing with and a police member was assaulted outside the ground,” he said.
“The level of violence is getting worse – but that’s not just a footy issue, it’s a whole of society issue.”
Last week, AFL boss Gillon McLachlan labelled the brawl “incredibly disappointing” and “completely unacceptable”, while flagging the league’s intention to take action.
AAP has contacted the AFL to confirm whether any bans were imposed to those involved.
