Franck Ribery could miss Bayern Munich's Bundesliga opener against Borussia Monchengladbach on August 7.
The France international sustained an ankle injury on Sunday and was forced to leave the training pitch due to the knock. Bayern released a statement shortly afterwards that the ankle problem was not serious and that Ribery would be out of action for only three or four days.
However, Bild now report that the 28-year-old has damaged the ligaments in his left ankle, and that he could consequently miss Bayern's Bundesliga opener, with the player required to wear a cast for the next five days and could resume running exercises in 10 days.
"The injury is a bit worse than we expected. I don't know why this is always happening to me, but I have to be strong now. I don't know whether I'll be match fit in time for the game against Gladbach," Ribery said to Bild.
Ribery will definitely miss the upcoming DFB Pokal match against Eintracht Braunschweig on August 1 due to the problem.
