Bayern Munich have confirmed that goalkeeper Pepe Reina will be sidelined "for the next few weeks" with a calf complaint.
The Spaniard picked up the injury during a Paulaner Cup encounter last night.
It is expected that Reina will now undergo a scan, but Bayern do not expect the stopper to return to action until December at the earliest.
The 32-year-old joined Bayern from Liverpool on a three-year deal during the summer.
