Bayern Munich will be without Arjen Robben for Saturday's Bundesliga match with Freiburg and he is also in danger of missing his side's Champions League opener against Villarreal next Wednesday.
The Dutch winger is recovering from back and groin injuries and resumed training with the Bayern squad on Monday, but still needs more time, according to the club.
After four league games, Bayern are top of the league and host Freiburg at Munich's Allianz Arena, before travelling to Spain to take on Villarreal in Group A.
"He is still feeling pain," admitted Bayern coach Jupp Heynckes on Friday, as he confirmed that Robben is still unfit for this weekend, rather than simply being rested with the Champions League game in mind.
"We have not fixed a date for his return."
Yesterday, Bayern sporting director Christian Nerlinger appeared more optimistic as to the player's prospects, saying: "Arjen Robben is on the mend, although I don't know if he will be fit to face Freiburg.
"The main thing in his case is that it won't be a long-term problem. This groin inflammation has caused trouble in the past, but it's looking good for him now."
Having missed out on Germany's recent win over Austria and draw with Poland with a thigh strain, striker Mario Gomez will be back in action after returning to training on Tuesday.
"The leg is giving me no more problems," said Gomez.
