Kane missed his team's final training session before the match at the Allianz Arena and has suggested he could be out for his team's next game.
"We'll have a scan tonight and then we'll see. I'm not sure if I can play against Frankfurt on Sunday. Now we'll just have to keep our fingers crossed," Kane told reporters.
"Harry played with problems," sports director Max Eberl said. "Hopefully it will be enough until Sunday."
