FC Bayern München will be without Arjen Robben for up to six weeks after the Dutchman suffered a groin injury in Saturday's pre-season friendly win over SV Lippstadt 08.
The 32-year-old winger, who was making his first appearance following four months on the sidelines, scored Bayern's second goal in an eventual 4-3 success, but was forced off after just 35 minutes.
"It's a real blow," lamented Bayern captain Philipp Lahm. "Anyone who knows Arjen knows how much he loves to be on the football pitch - and that goes for friendlies like these, too."
Robben's latest setback comes after a 2015/16 campaign beset by groin problems, which restricted him to just 22 appearances in all competitions.
