Adelaide United's A-League Women head coach Adrian Stenta and the assistant mentor of the club's A-League Men team, Ross Aloisi, have both contracted COVID-19.
The pair, who are both fully vaccinated, will be absent from this Saturday's double header at Hindmarsh Stadium against the Melbourne Victory.
Adelaide said on Thursday no players from either the men's or women's teams had tested positive with both fixtures expected to go ahead as scheduled.
Aloisi had been standing in for head coach Carl Veart, who has now recovered from COVID-19 and will return to the dugout on Saturday.
Joe Mullen will take charge of the women's team.
Infections over the last month have forced a raft of postponements across both competitions, with just three of six A-League Men games given the go-ahead to proceed this weekend.
Under the competition's rules five positive cases among players is the threshold for a postponement.
Perth Glory's women's team, who are currently based in NSW, recorded three cases on Wednesday while two members of the football staff also received positive results.
Perth expect Sunday's fixture with the Newcastle Jets to still go ahead as planned.
