Haaland has been missing from the Dortmund squad since scoring in BVB's win over Hoffenheim on Matchday 20 due to a groin injury.
Despite returning to training this week, the 21-year-old was not on the plane to Scotland with his teammates for their UEFA Europa League playoff second-leg meeting with Rangers.
Rose explained before the game that Haaland was left behind because he is still feeling pain.
"He's still a bit away from 100 percent," said Rose. "We're in exchange, he tries and does all he can.
"He and we don't want him to get hurt again. He still needs some time. He needs to be pain-free. And we're not there yet."
After they return from Glasgow, Dortmund face Augsburg in the German top-flight on Sunday but it looks like they will again do so without the services of their top-scorer.
