“Now that the fixtures are out, we’ll be working with Rangers and will no doubt be talking with teams they are scheduled to play at home against and let’s see what emerges,” he said.
“We will certainly do what we can to be as helpful as we can whilst trying to be as fair as we can to all parties.”
Rangers visit Heart of Midlothian in the season’s opening Premiership fixture on Saturday, 3 August, with their first home game scheduled for a week later against Motherwell.
Philippe Clement’s side are also due to host Ross County on 24 August, while they are involved in the Champions League third qualifying round on 6/7 and 13 August, with a potential play-off round tie later in the month.
The SPFL remains in discussions with Rangers about their August fixtures and Doncaster stated: “I fully understand how these projects don’t always go to plans.
“We’ll be liaising as closely as we can with Rangers and trying to do our best to assist in what clearly is a difficult situation they find themselves in.”
The Ibrox club has yet to tell the SPFL how they wish to progress, although it would appear that a request for match postponements is the least likely scenario.
“Rangers will have a better handle on what sort of delay they are looking at and we’ll certainly do our best to respond positively to what they request,” Doncaster added.
“Ultimately these are works at Ibrox. They will be in the best position to judge what flexibility they need and no doubt will be asking us and other clubs as well for flexibility.”
