Celtic could also be in the same boat, with Kyogo Furuhashi, Daizen Maeda, Reo Hatate, Yosuke Ideguchi, Tom Rogic and Cameron Carter-Vickers also facing potential call-ups.
However, as far as Van Bronckhorst is concerned, it’s business as usual.
"There's still a long way to go until the Old Firm,” said Van Bronckhorst. "Right now we're preparing for Aberdeen.
"The [Old Firm] game is in two weeks, a lot can happen in that period of time.
"But as far as I'm concerned, we're not thinking about postponing the fixture.
"We know it's going to be an international week and we might lose some players as well but that's the way it is.
"We have to take it as it comes. It's not only one [international] game, it's three games that have to be played in the window.
"I think it's impossible, especially with bringing the break forward. [The SPFL] have already said it's difficult and there's no space for postponing games."
