"The Board of the SSA OMFNL is holding a Special meeting on Wednesday night to discuss its response to the Coronavirus situation," chairman David Sinclair said in a statement.
"Like all organisations we are in unchartered territory.

Further announcements will be made post our meeting Wednesday night."

It's a bitter blow for the league, albeit not unexpected given recent events.
The VFL season was suspended on Monday for the foreseeable future. It follows Richmond VFL's decision to suspend its VFL program.
The O and M was scheduled to start with a stand-alone match between Albury and Wodonga Raiders on March 28.
Although more will be known after Wednesday night's meeting, the league had a stack of blockbusters in the first month, including three over the Easter weekend with the rejuvenated Yarrawonga hosting Wodonga Raiders in its annual game at Mulwala.
The prospect of losing Easter games would have a massive impact, particularly on Yarrawonga, Myrtleford and Corowa-Rutherglen.
The Anzac Day round was scheduled for round four.
