"The SPFL directors have a key role to play in navigating those challenges and I'm pleased to welcome them on board for what promises to be a unique season ahead.
"Thanks to the dedication of thousands of people involved in our game, we are within touching distance of matches being resumed.
"It's vital that we maintain that vigilance and discipline as we move towards a greater semblance of normality for our teams and for the supporters up and down the country who form the backbone of our sport.''
