The French wizard, who has just recovered from a hernia problem, went down in agony on 64 minutes as Thomas Muller scored the equalizer for the Bavarians.

Bayern manager Louis van Gaal voiced his concern before Ribery's scan, but the Dutchman seems to be relieved by the news on his star player.

"I had feared worse," said Bayern coach Louis van Gaal after the news.

"Our misfortune is a blessing in disguise. Now we can look to getting Franck cured properly."

Bayern already miss talismanic winger Arjen Robben due to a long-term knee problem.
