Bayern breathe sigh of relief over Ribery
The club had initially feared the injury could rule the winger out for much longer.
"I am happy and very relieved," said Ribery after leaving the medical centre on crutches.
The 27-year-old France international, who missed almost two months because of a torn right ankle ligament earlier this season, was brought down by Josue on the edge of the box in the 17th minute.
He was briefly treated but limped off, supported by two Bayern doctors, to be replaced by Arjen Robben, who was making his first appearance this season after recovering from a muscle injury.
Injury-hit Bayern are 16 points adrift of league leaders Borussia Dortmund after 18 games.
