The Real Madrid loanee had to leave the field after coming on as a second-half substitute
James Rodriguez will need tests on a calf injury after Bayern Munich's 1-1 draw at Nurnberg, says head coach Niko Kovac.
Colombia midfielder James came off the bench early in the second half during Sunday's Bundesliga clash, but he lasted only 15 minutes before having to be replaced himself, with Alphonso Davies coming on.
Despite the blow of losing James, Serge Gnabry equalised to cancel out Matheus Pereira's opening goal and the Bundesliga leaders had a lucky escape in added time when Tim Leibold's penalty came back off the post.
