Kenny Jackett wants the Blues’ next home match against Gillingham to go ahead as planned.
Pompey can request for the game – scheduled to take place on Saturday, October 12 – to be called off after having three players selected for international duty.
Craig MacGillivray has been chosen by Scotland, with Ross McCrorie expected to skipper their under-21s and Ronan Curtis in the Republic of Ireland squad.
And Jackett will wait to see if any injuries are collected at Doncaster before deciding whether to postpone the fixture.
The Blues boss said: “I’m going to play the game if at all possible because we don’t want to go 14 days between league matches.
“We congratulate Craig, Ronan and Ross on their call-ups and we’ll have to see whether Ryan Williams is also away, with the Australia squad announced tomorrow.
"I’m going to play the game if at all possible because we don’t want to go 14 days between league matches."
“That might have an impact and we’ll also assess the injury situation, so we’ll make a decision on Saturday night or first thing on Sunday.”
Pompey have no fresh injury concerns for their clash with Rovers at the Keepmoat Stadium this weekend.
Jackett said: “We’re okay and looking at the same players as last week. There aren’t any new problems, which is good news.
“Tom Naylor was probably the last to train this week after suffering a couple of heavy knocks in successive weeks.
“The worst was at Wycombe, but having no midweek game has helped us. He’s shrugged that off and is ready to go again.”
