The task force examining reconstruction of the Scottish leagues lost a high-profile member just before its first meeting as Hibernian chief executive Leeann Dempster pulled out.
Hibs announced Dempster would concentrate on helping Scottish football get into a position to welcome back crowds.
The decision came after First Minister Nicola Sturgeon admitted there would be no chance of mass gatherings soon and stated some form of social distancing would possibly be required until a Covid-19 vaccine is available, while expressing concerns about closed-doors matches.
A brief Hibs statement on Twitter read: "@LeeannDempster will work with other Scottish clubs on the biggest issue facing our game - to identify how and when football supporters can safely return to Scottish grounds. Leeann will take no part in the SPFL's working party on reconstruction."
Dempster's withdrawal left co-chairs, Hearts owner Ann Budge and Hamilton director Les Gray, as the only top-flight representatives.
The group was set up by the SPFL in the wake of the decision to terminate the three lower divisions as they stood with a view to doing the same with the Premiership.
