This will impact the Greater Western Victoria Rebels girls' round three encounter with Western Jets at Mars Stadium on Saturday and the boys' practice matches against Geelong Falcons at Mars Stadium on Sunday.

Sunday's programming included two under-18 games and one under-16 match.

NAB League country manager Lee Fraser, in a circular to clubs, said the health and safety of staff, players and fans was paramount.

"Therefore we want to reassure our football community that we are regularly consulting with the Australian Government, the World Health Organisation and the AFL's chief medical officers.

"Further, the health and safety of players, male and female, underpin our ability to conduct matches and provide the content that is so loved by our many fans, families, friends and supporters.

"As a result, we as an industry must do all we can to protect our players from contracting Covid-19 by mitigating any potential impact on being able to play matches.

"Therefore, we are keen to put protocols in place for the weekend of NAB girls' games and NAB League boys' practice games."
