Bayern Munich and France winger Kingsley Coman is set to miss "several weeks", including Wednesday's Champions League quarter-final against Arsenal after injuring a leg in a 2-0 win over Cologne, the club announced on Saturday.
Coman was helped off the pitch early in the second half on Saturday, needing the assistance of two Bayern staff members as he could not put weight on his leg.
"Kingsley Coman will be out of action for several weeks after the forward suffered an injury in his right adductor muscle," Bayern said in a statement, explaining "this was confirmed by an examination from the club's medical department."
Bayern coach Thomas Tuchel said Coman would definitely miss Wednesday's second leg at home to Arsenal. The forward's participation at Euro 2024 is also at risk.
The first leg of Bayern's European tie in London ended 2-2 on Tuesday.
"It's a big downer which overshadows the victory a little," Tuchel said at the post-match press conference.
Bayern sporting director Christoph Freund said Coman "still needs to do some tests but it doesn't look good."
"We hope it won't be counted in months. We'll see what the test says but we'll expect him not to be available for several weeks."
Tuchel said his side needed to "throw everything into it" against Arsenal on Wednesday, telling reporters "let's hope the home advantage is the decisive advantage."
Coman had only recently returned from a torn knee ligament that kept him out from January to March.
Euro 2024, to be hosted in Germany, starts on June 14.
