Central Highlands Football League is encouraging everyone attending junior games on Saturday to wear masks.
CHFL president Doug Hobson said this was an opportunity for the football community to take the initiative.
He said although a state government ruling making the wearing of face masks in public compulsory would not be introduced until Monday, everyone needed to do everything within their power to fight the spread of COVID-19.
"This virus is waiting for no one.
"If we want to keep football going we need to do all we can.
"It makes good sense."
Hobson said some clubs had already acted, getting on the front foot and advised members and supporters to wear masks on Saturday.
The CHFL has already had some scares, with players from two clubs having to be tested for COVID-19 after potentially being in contact with persons who have tested positive.
While these players - two Newlyn under-18s and one Ballan under-15 - returned negative tests, several clubs have withdrawn from the competition.
Newlyn and Daylesford pulled out their under-12, under-15 and under-18 teams late last week, while Bungaree and Springbank followed suit early this week. Rokewood-Corindhap has also withdrawn its under-18 side, but will continue to play in the under-15s and under-12s.
Even though the CHFL has clubs in the Golden Plains and Moorabool shires with junior teams, the competition has not been impacted by new state government-enforced restrictions in these municipalities, which bans households from having visitors.
Round four matches will be played Rokewood (Golden Plains), Ballan (Moorabool), Snake Valley and Hepburn on Saturday.
