A half-time incident involving players, officials and supporters from Allansford and Nirranda football clubs is being investigated.
Warrnambool and District Football Netball League president Michael Harrison said the investigation had been launched after Saturday's match at Allansford Recreation Reserve.
This, Harrison said, could result in anything from a "please explain" to a formal investigation and would be completed "within a reasonable time".
Harrison said the WDFNL board had requested AFL Western District seek information from the two clubs before the next step was decided.
Nirranda coach Shane Threlfall said umpires spoke to him at half-time and indicated the game could be called off if emotions did not settle down.
"I think they did a great job and things calmed down in the second half - everything was played in great spirit after that," he said.
"We told the boys the best way to react was to hit the scoreboard and win the game.
"I was really proud of the way our players responded. Their focus was on the ball and playing our brand of footy."
Threllfall said he and Cats coach Ben Price shook hands after the game but did not discuss the half-time incident.
Price said the umpires spoke to Allansford captain Justin Fedley at half-time, but couldn't contact him.
He said he was "rattled" at half-time and didn't address his players for more than 10 minutes, but agreed the spirit of the game improved after the main break.
"Compared to how the first half was played, the second one was much better, even though there were two send-offs," Price said.
Nirranda won the match by 82 points.
Meanwhile, East Warrnambool's Josh Stennett has been charged with "intentionally making contact with an umpire" and will face an AFL Western District tribunal at a date to be confirmed.
Stennett, who has played five reserves games and two senior games for the Bombers this season, allegedly made contact with field umpire Michael Lowther during the fourth quarter of East Warrnambool's loss to Kolora-Noorat on Saturday.
